Jazz is a music tradition that took shape in African American communities in New Orleans in the early twentieth century. It drew on blues, ragtime, brass band music and African-derived rhythmic practices, and it is characterized by swing, syncopation, blue notes and improvisation over a shared harmonic framework. Like other music traditions, it combines composed structure with spontaneous performance, but it places unusual weight on the individual player's real-time invention and on the interaction of musicians within a group.
Jazz matters for several reasons. Its stylistic lineage, from New Orleans ensembles to bebop, modal and free styles, and later fusion and global scenes, is one of the most documented in twentieth-century music. Its concepts, including swing feel, extended harmony and the soloist's role, shaped rock, rhythm and blues, funk and hip hop, and it influenced classical composers, writers and visual artists. Its history is also bound up with segregation, migration, the commercial music industry, and debates over authorship and cultural ownership, all of which bear on how it is understood today. Its practices have been recognized as part of the cultural heritage of the United States and are studied and taught internationally, as the intangible cultural heritage framework and the work of UNESCO suggest in the broader context of living traditions.
The entry first defines jazz and examines its musical elements. It then traces its development chronologically, from its African American roots and early New Orleans ensembles through the recording era, the swing and big band years, bebop, cool, hard bop, modal and free jazz, and fusion. It then covers the Latin, Brazilian and European exchanges, forms and instrumentation, the economics and media of jazz, education and transmission, the late-twentieth-century and contemporary periods, influence on other arts, institutions and recognition, and the scholarly debates that remain unsettled.
Definition and defining features
Jazz is better understood as a set of performance practices than as a single fixed style. Its repertoire runs from early New Orleans ensemble music to electronic fusion, and what links these forms is a way of making music in which composed material and spontaneous invention exist side by side. A performance may follow a written melody, a chord chart or a modal framework, but soloists are expected to create new lines within it, so the same tune can sound very different from one performance to the next.
Several traits recur across most of these practices. The first is swing and syncopated rhythm. The beat is divided unevenly, so pairs of notes are often played long-short rather than equally, and accents fall off the main beats. The second is improvisation over chord progressions, in which players build new melodies on the harmonic framework of a tune or a twelve-bar blues. The third is the use of blue notes and bent pitches. Thirds, fifths and sevenths are typically lowered or inflected, then slid into, bent or growled, which gives the melody a vocal quality. The fourth is call-and-response between players. A phrase from a soloist may be answered by a horn section, or one instrument may echo a lead line in another voice.
The contrast with classical music lies largely in who shapes the performance in the moment. In the classical tradition, a score usually fixes pitch, rhythm and most dynamics, and the performer's role is interpretation within those limits. In jazz, the written material is often a starting point. A theme, called the head, is stated, after which soloists take turns improvising, and the arrangement may change from one performance to the next. Popular song is a closer neighbour. Many jazz performances draw on songs from the popular repertoire, and early jazz was itself dance and popular music. The boundary has moved over time. Jazz absorbed popular songs as standards, while pop and rock later borrowed jazz harmony and improvisational methods. The categories are therefore better seen as overlapping than as fixed.
The rhythm section, usually piano, double bass, drums and often guitar, supports the front line of soloists, which is typically made up of trumpet, saxophone, trombone or clarinet. The pianist or guitarist comps, playing chords in rhythmic patterns that outline the harmony and leave space for the soloist. The double bass supplies the harmonic foundation, often through walking bass lines, while the drummer keeps time and shapes the energy of the performance. Because the rhythm section responds to the soloist by adjusting density, accents and dynamics, the group operates as a continuous exchange rather than as a backing track.
Musical elements: rhythm, harmony and melody
Swing feel and the rhythm section
Swing is the most recognisable rhythmic property of jazz. It works by changing where subdivisions fall inside the beat while the tempo itself stays constant. Notes written as straight eighths are performed as a long-short pair, and the second note arrives later than a straight grid would place it. The beat should not slow down or speed up. Only the placement of the subdivision changes. A common teaching device divides each beat into three, then sounds only the first and last parts, which leaves the middle one silent. Players do not apply this ratio mechanically. Real swing is often more flexible than an exact triplet grid. At faster tempos, swing eighths often become less uneven, while at slower tempos the long-short shape may be more obvious.
The drummer's ride cymbal usually carries this feel. Its pattern is built on the triplet grid and skips the third triplet part consistently. The ride also sets the emphasis: when the bass is walking in four, the ride should be accented on beats 2 and 4, which creates the tension the music needs to move forward. The bassist's walking line supplies the quarter-note pulse that the ride and the other players measure against. A quarter-note pulse on the ride is aligned with the quarter notes of the walking bass line. Snare and bass drum act differently. Rather than locking into a repeating figure, they interject around the other musicians while the ride and hi-hat keep a steady, swung, triplet-based pulse.
Harmony
Much of jazz harmony rests on dominant seventh chords and their resolutions. The characteristic tension of a dominant seventh comes from the pairing of its third and seventh, which together form a tritone. The ii–V–I cadence, in which chord roots descend by fifths from the supertonic through the dominant to the tonic, is the most common progression in the repertoire. Tritone substitution works very well on standards, because their chord progressions typically use the ii–V–I progression and the circle of fifths.
The tritone substitution replaces the dominant with a dominant seventh whose root lies a tritone away. In the progression Dm7–G7–Cmaj7, the G7 can become D♭7. The third and seventh of the two chords are the same pitches with their roles exchanged, so the harmonic function is preserved. The bass moves by half steps instead of a fifth. The root of the ii chord moves down a half step to become the root of the ♭II7, which moves down another half step to become the root of the I chord. Chord extensions such as ninths, elevenths and thirteenths, together with altered tones, add colour on top of these skeletal progressions. Later in the twentieth century, some players moved away from chord-by-chord changes and based improvisation on modal scales, a development covered in the modal jazz section.
Melody and timbre
Jazz melody is shaped as much by pitch inflection as by the notes themselves. A blue note is a pitch that is flattened or varied for expressive effect, often the 3rd, 5th or 7th degree of the scale. A piano can only approximate these pitches with fixed keys, whereas singers, brass players, guitarists and saxophonists can shade them between standard semitones. Instrumentalists also bend, smear and growl notes, which gives them the quality of a voice rather than clean, fixed pitches.
Vibrato is treated as a variable rather than a constant. Jazz vibrato varies between players and periods. Saxophonists are often advised that it is slower and more deliberate than classical vibrato. The growl is a related timbral device. It changes the timbre of a note, giving it a raspy quality that adds intensity and expression. One common method is for the player to hum while sounding the note. The rough, forceful timbre associated with brass and reed players in early jazz, often described as "hot," draws on these same techniques. A trumpet note may sound bright and clean, brassy and forceful, muted and intimate, or rough and vocal, depending on the player, register, articulation and equipment.
Polyrhythm, cross-rhythm and ensemble texture
Jazz rhythm is typically built from several layers that move at once: a steady pulse, a swung subdivision, accented figures from the horns and the drum kit, and bass lines that sometimes conflict with the melody's accents. Polyrhythm, in which two or more incompatible metric groupings sound together, and cross-rhythm, in which accents are placed against the prevailing meter, are often traced to West and Central African drumming and vocal practices carried into the Americas. These features became central to jazz through the rhythm section's ability to keep several rhythmic strands going independently, so that the ensemble sounds like a dense, interlocking texture rather than a single line over a block of chords.
African American roots and precursors
The Black musical practices that fed into jazz were mostly transmitted by ear, so their early history has to be pieced together from later testimony, notated arrangements and scattered descriptions. Most early African-American music is based on an oral tradition and was not written down. The phonograph arrived after many of these developments had already taken place, so no aural record exists for much of the earliest material.
Vocal traditions of the nineteenth-century South
Work songs formed one of the first strands. Enslaved workers sang while they labored, and the solitary field holler, a cry that often incorporated call and response chants tinged with falsetto whoops called "arwhoolies." These songs did more than set a rhythm: they allowed emotional expression, helped pass the time, and coordinated labor movements. Their musical logic also carried forward, since the call-and-response structure, repetitive phrasing and improvisation found in these songs became foundational elements of jazz. Field hollers were also marked by bent tones, a feature that later became a defining trait of blues-based melody. Spirituals drew on the same practices, adding Christian texts to call-and-response singing and to great emphasis on rhythm with hand clapping and foot stomping. Some spirituals carried coded messages about escape and freedom. The ring shout, a circular ritual in which worshippers moved while shuffling, stomping and clapping, offered another model of communal rhythm. Underlying these forms, West African musical concepts were brought to the New World by slaves and were assimilated with European music.
Brass band, marching band and dance traditions
In New Orleans, the instrumental side of the roots came from brass and dance bands. New Orleans jazz evolved from African and Caribbean call-and-response chants and drumming practiced by African Americans in the city during the post–Civil War era, and from the dance music played by brass bands that became popular there. Many early musicians started out performing in ragtime-style syncopated brass bands that played for funeral ceremonies. The Excelsior Brass Band, for example, was a brass band from New Orleans active between 1879 and 1931. The resulting instrumentation, derived from funeral, brass, and dance bands, centred on cornet, clarinet, trombone, tuba, banjo, and drums.
A distinct role was played by Creole musicians. Those of the downtown district were generally regarded as being in better financial standing, and better educated—musically and otherwise. They could usually read sheet music, while uptown Black musicians often played by ear. Historians generally agree that jazz took shape where these two groups met. Some musicians of this period could read sheet music and improvise, and that combination would prove central to jazz's identity. The conservatory and amateur traditions blended in the process, and new technology such as the trap drum set helped shape the resulting ensembles. William Manuel Johnson's Original Creole Band, a group of Creole and African American musicians from New Orleans, toured the Pantages theater circuit from 1914 to 1918.
Ragtime and sheet music
Ragtime supplied the syncopated keyboard idiom. It originated in African American communities in the late nineteenth century and was propelled to popularity in the 1890s to 1910s by composers such as James Scott, Joseph Lamb, and particularly Scott Joplin. Its rhythm combined the syncopated rhythms of African music and African-American banjo music with the harmonies and formal patterns of European march and dance music. The piano rag became a specific type of composition, with the formal structure of a march, and a complex, syncopated right hand part over a steady beat in the left hand. The left hand's steady pulse supported the right hand's syncopated counter-rhythms, which produced the characteristic bounce.
Publication was the means by which ragtime spread. The label first appeared in the mid-1890s on popular songs with syncopated melodies and piano music with distinctly syncopated right hand rhythms. The first published piano rag was "Mississippi Rag" by William Krell in 1897. Joplin's "Maple Leaf Rag" from 1899 was the first to sell over a million copies. Copies of the sheet music for rags and ragtime songs, written by scores of composers, both black and white, were sold by the thousands. Dance also drove this spread: the cakewalk, a couples' dance, is cited by some scholars as an antecedent of the style, and it took elements of ring shouts into a secularized format that satirized the stiff, formal waltz dancing of white people.
The blues as a song form
The blues emerged as a distinct form in the decades after emancipation. It is a music genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. Its lineage ran directly through earlier vocal practice: the blues developed from slave music such as the work song and field holler, and from the sacred spiritual. Its vocabulary also absorbed spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. Blues musicians, a generation of traveling musicians, carried these songs across the South, and the form was eventually standardized into a 12-bar form. The twelve-bar pattern, with its repeated lines and characteristic harmonic cycle, became the frame on which early jazz players improvised, while blue notes and bent pitches derived from field hollers colored the melodic line.
New Orleans and early jazz (c. 1900–1920)
Early jazz grew out of the social life of New Orleans, where music marked everyday occasions as well as nightlife. The funeral procession was one of the most important of these settings. The New Orleans tradition of the funeral procession grew in the 19th century. Mourners would walk from the house of the deceased to the cemetery behind a band. On the return, the band would switch to upbeat, celebratory music, and the crowd would dance behind it. That second part of the procession came to be called the second line. Street parades, dance halls and saloons offered other outlets, and the performance style of the period was looser there. Early jazz became a fixture of the clubs of the red-light district, where musicians could play in a rowdier and more improvisational manner.
The Storyville district, named for the councilman whose boundaries defined it, was a major venue. The district was named after councilman Sidney Story, who drafted its boundaries so that authorities could regulate and monitor illicit activity. Although New Orleans jazz did not originate in Storyville, the music flourished there. Many visitors to the city first heard jazz performances in Storyville and in the all-Black streets of uptown New Orleans.
The cornetist Buddy Bolden is the most frequently cited figure of this generation, though no recordings of him survive. By 1895 he had organized a hot-jazz ensemble that became a model for New Orleans bands, made up of six or seven men playing cornets, clarinet, trombone, double bass, guitar and drums. Rather than imitating other cornetists, he played what he heard by ear and adapted it to his horn, fusing ragtime, sacred music, marching-band music and rural blues. He also reshaped the dance band: string instruments became the rhythm section, while clarinets, trombones and his cornet formed the front line. Later cornetists took up his role. The title of "King" held by Bolden passed to Freddie Keppard and then to Joe Oliver. Oliver won a "cutting contest" against Keppard, a contest format that remained central to the way players learned and proved themselves. Keppard's recorded legacy is slight: he left New Orleans as a professional in 1910, turned down a recording opportunity in 1915, and did not record until 1926.
Jelly Roll Morton, who was of Creole background, became the most prominent composer of the period. He was described at the time as New Orleans' greatest jazz composer. The collective style of these ensembles was built on several melodic lines played together over a shared rhythmic pulse, with each instrument taking a role in the texture; the front line and rhythm section were distinct but interdependent.
The first commercial jazz recordings came from a white band. The Original Dixieland Jass Band consisted of five musicians who had played in the Papa Jack Laine bands, which performed for parades, dances and advertising in New Orleans. On February 26, 1917, the group recorded for the Victor Talking Machine Company in New York. The sides "Livery Stable Blues" and "Dixie Jass Band One-Step" were issued as Victor 18255 in May 1917, the first issued jazz record. "Livery Stable Blues" sold hundreds of thousands of copies. The band later changed the spelling of its name to "Jazz" in late 1917. Its status as the first recording is still debated, and the band's advertising drew on Black caricatures in the minstrel tradition, a point historians have examined closely. Black musicians such as Joe Jordan also had claims tied to the repertoire: Joe Jordan sued, since the "One Step" incorporated portions of his 1909 ragtime composition "That Teasin' Rag".
The music spread northward as musicians moved. The Original Dixieland Jass Band got its first big gig in Chicago, and in 1917 it moved to a residency in New York. Other New Orleans musicians soon followed the band's path and arrived in New York to play jazz. Chicago drew many more players during the 1920s. The Chicago music scene attracted Louisiana-born clarinetists such as Jimmie Noone, Johnny Dodds and Leon Roppolo, along with pianists such as Earl Hines from Pittsburgh. Westward movement also happened: Jelly Roll Morton and Bill Johnson briefly lured the trumpeter Buddie Petit to Los Angeles in 1917, but he returned to New Orleans after objecting to the expectations placed on him. These moves carried New Orleans ensemble habits into the northern cities, where they would be reworked in the recording studios and dance halls of the 1920s.
The recording era and the rise of the soloist (1920s)
The spread of phonograph records in the 1920s changed both how jazz was heard and how it was played. Early discs were cut acoustically: players stood around a recording horn, and the balance of a group depended on which instruments could project into it. Around mid-1925 the industry began to switch to microphones, and electrical recording, which the electrical process made possible, was introduced that year. Some labels moved slowly. Harmony Records, for example, avoided electrical recording for financial reasons, because it would have had to pay royalties to Western Electric, and the acoustic process was largely abandoned only by 1928. Microphones made quieter instruments such as banjo, piano and string bass easier to capture, and they allowed a single voice to stand out from a dense ensemble texture, which encouraged a more soloist-centred sound.
The clearest example of this shift is Louis Armstrong's Hot Five and Hot Seven series. The first session, on 12 November 1925 at the OKeh studios in Chicago, was Armstrong's first set of records under his own name. The band drew mostly on King Oliver's Creole Jazz Band, with Johnny Dodds on clarinet, Kid Ory on trombone, Johnny St. Cyr on banjo and Lil Hardin Armstrong on piano. The group was essentially a studio ensemble and recorded for OKeh through 1928. In 1927 it was expanded with tuba and drums under the name Hot Seven. Armstrong's 1927 "Potato Head Blues" is often singled out for its two improvised solos, which are regarded as a breakthrough in jazz phrasing and swing. Within these records, the collective front line of New Orleans style gave way to arrangements in which the leader's improvised lines were the focal point.
Armstrong is also associated with scat singing, the use of nonsense syllables to imitate instrumental improvisation. His recording of "Heebie Jeebies" on 26 February 1926, released by OKeh that spring, became his first hit and contains a famous scat chorus. A popular story says that he dropped his lyric sheet during the take and improvised out of necessity, but this account is disputed. Vocal improvisation with syllables predates the record: Gene Greene recorded scat choruses between 1911 and 1917, and Don Redman and Fletcher Henderson featured scat vocals on a 1925 recording. The 1926 performance is nonetheless treated as the turning point that established the techniques later used in modern scat.
Other soloists of the decade extended the same emphasis on individual voice. Sidney Bechet, a clarinettist who first recorded in July 1923, was one of the first important jazz soloists. During a stay in London he took up the straight soprano saxophone and became the first influential player on that instrument, using a broad vibrato and an intense, emotional tone. The cornetist Bix Beiderbecke, who made his recording debut in February 1924 with the Wolverines, developed a more relaxed, lyrical approach to the solo, which made him a model for later white jazz players. The critic Terry Teachout has described Armstrong and Beiderbecke as the two most influential figures in early jazz.
Jazz was also central to the mood of the decade. The novelist F. Scott Fitzgerald named the 1920s "The Jazz Age" in The Great Gatsby (1925), and the music's popularity rested on dance halls, nightclubs and a growing market for records. Commercial success did not always match artistic ambition, but the records of this period established the soloist as the centre of jazz performance, a model that shaped the swing and bebop styles of later decades.
Regional centers and migration (1920s–1930s)
The Great Migration and the northern cities
Jazz spread in the 1920s largely because of population movement. Black Southerners relocated in large numbers to northern industrial cities, and urban life there gave the music new audiences and employers. Musicians travelled the same routes. Between about 1916 and the end of the 1920s, at least 75,000 Southern immigrants arrived on Chicago's South Side. Many of them had left farm work and took jobs in the city's stockyards, steel mills and factories, which gave them spending money for entertainment. Jazz musicians found the South Side's entertainment district, known as "The Stroll," a busy market for their services. In Chicago, the hot jazz style emerged, characterised by faster tempos, more complex improvisation, and a focus on solo performance. The New Orleans musicians who arrived in 1918, including Freddie Keppard, Sidney Bechet and King Oliver, found that local players had already adapted the New Orleans style to Chicago tastes.
Other cities developed their own scenes. Harlem, Chicago's South Side, Kansas City, Detroit's Paradise Valley and Los Angeles's Central Avenue each became a dense Black cultural district with its own clubs and bands. New York's Harlem, Chicago's South Side, the wide-open streets of Kansas City Missouri, the Paradise Valley neighborhood in Detroit, Central Avenue in Los Angeles, and many other new jazz-rich big-city enclaves all across the country became proving grounds for America's music.
Chicago and the Grand Terrace
Louis Armstrong's move to Chicago in 1922, at the invitation of his mentor Joe "King" Oliver, is the best-known example of this migration. Earl Hines moved to Chicago in 1925 after working in Pittsburgh and touring with bandleader Lois Deppe. He met Armstrong in 1926, and the two worked together on the sessions that produced the Hot Five and Hot Seven records. Hines's piano style became the defining Chicago approach. He played melodies in octaves with his right hand, with single-note lines and rhythmic chords in the left, a method often described as "trumpet style." Pianists in Chicago widely imitated it.
In December 1928 Hines opened his own big band at the Grand Terrace, a South Side nightclub. The club's success made it a tempting target for underworld takeover, and it was under mob ownership within two years of opening. Al Capone was among its patrons. The club also became a key broadcasting venue. For many years, the Hines big band broadcast live from the Grand Terrace, garnering a huge nationwide audience. Many later pianists, including Nat Cole, Teddy Wilson and Art Tatum, said that they learned from these broadcasts. Hines's residency there lasted about twelve years, and his career ran in parallel with Duke Ellington's engagements at the Cotton Club in New York.
Kansas City and the territory bands
In the 1920s the rapid spread of jazz led to the rise of "territory bands," bands located throughout the Midwest and Southwest, which designated a specific city, often a small one, as home base and played dance dates throughout the surrounding territory. Kansas City became the most important hub of this network. Its nightlife, which operated under the political machine of Tom Pendergast, kept clubs open around the clock, and visiting bands competed in Kansas City jam sessions that went on well beyond sunrise, fostering a highly competitive atmosphere.
The first major Kansas City bandleader was Bennie Moten, who had formed his own band in 1918 and made the first recordings of the Kansas City style in 1923. Moten's band became a model for the Kansas City sound, which was based on ragtime and blues. Kansas City jazz typically featured a full, big-band sound, with simple arrangements that were based on riffs, or two-to four-bar musical phrases, rather than on fully developed melodies. This structure left room for individual soloists, and some of the most important soloists in jazz developed within the Kansas City bands, including Coleman Hawkins (who left Kansas City early, in 1922), Ben Webster, Herschel Evans, and most importantly, Lester Young and Charlie Parker.
Rival groups, most notably Walter Page's Blue Devils, had come from Oklahoma City. Page, a bassist, pioneered the "walking" bass style that became the rhythmic underpinning of swing and bebop. Count Basie joined the Blue Devils and then became the pianist with the Bennie Moten band based in Kansas City in 1929. Moten's death in 1935, after a routine tonsillectomy, ended the first great era of Kansas City jazz. Basie then formed his own orchestra, drawing on members of both groups, and his band developed a looser big-band arrangement that allowed freer soloing. This became the basis of the Kansas City swing style of the later 1930s.
Harlem and stride piano
In New York, Harlem developed its own pianistic tradition, known as stride piano. The style combined a steady bass figure that alternated low notes and chords with melodic and syncopated playing in the right hand. James P. Johnson, the leading figure of the approach, influenced younger players, including Fats Waller, who brought stride into the entertainment and recording world of the 1920s and 1930s. Harlem's clubs, including the Cotton Club, served a largely white audience, and the district's cultural life was closely connected to the Harlem Renaissance. The stride tradition therefore became part of the wider Black literary and artistic movement of the period, while remaining a practical dance-hall and nightclub art.
Swing and the big bands (1930s–early 1940s)
The big band was the dominant form of jazz performance in the 1930s and early 1940s. A typical ensemble had roughly ten to seventeen players, arranged in sections: four or five saxophones (often doubling on clarinet and flute), three or four trumpets and three or four trombones. A rhythm section of piano, guitar, double bass and drums held the band together. The sections usually played written parts, and soloists improvised within them. The format therefore combined arrangement and improvisation at a scale that small combos could not reach, and it was built for dance halls, hotel ballrooms and radio.
Arrangers defined the sound of the era. Fletcher Henderson, whose orchestra played in New York in the 1920s, wrote for sections as units, setting saxophones against brass in call-and-response patterns and leaving room for individual solos. Don Redman, who was music director of McKinney's Cotton Pickers from 1927, pursued a similar approach and helped establish the riff-based section writing that later swing bands adopted. Henderson's arrangements were sold to Benny Goodman in the mid-1930s and became core repertoire for his orchestra, which shows how closely the style of the period depended on written charts. The ensemble's riffs, shout choruses and background figures gave dancers a predictable pulse while allowing the soloists to take risks.
Duke Ellington's orchestra took the format further. Its residency at the Cotton Club in Harlem, which began in 1927 and was broadcast on radio, gave Ellington a platform for writing around the distinctive timbres of his players, such as the growl trumpet of Bubber Miley and the plunger-muted trombone of Joe Nanton. Timbre thus became compositional material rather than a by-product of section playing. Ellington also pushed toward longer forms: "Creole Rhapsody" (1931) filled both sides of a 78 rpm record, and "Reminiscing in Tempo" (1935) occupied four sides. His "Black, Brown and Beige," premiered at Carnegie Hall in 1943, extended the orchestra into concert-length suites, a move that was admired by some critics and questioned by others.
Benny Goodman became the most visible bandleader of the swing era. His engagement at the Palomar Ballroom in Los Angeles in August 1935 is widely cited as the start of the swing era, and his radio programme drew large audiences. His concert at Carnegie Hall on 16 January 1938 is often described as the first jazz concert in that hall, and it included small-group performances with Teddy Wilson and Lionel Hampton, whose integrated groups within a white bandleader's organization were unusual at the time. The concert helped legitimize swing as art music, while the broader swing craze spread through ballrooms, records and films. Dancers in Harlem, particularly at the Savoy Ballroom, developed the Lindy Hop and its acrobatic variants, and the dance spread across the country as a social craze.
Segregation shaped the business at every level. The Cotton Club featured Black performers for white patrons but did not admit Black audiences, while the Savoy was a rare Harlem venue that drew integrated crowds. Many local musicians' union branches were segregated, which limited Black players' access to work in some cities. Touring Black bands were often confined to Black venues or to a narrower set of engagements. These conditions created ongoing tension between the demands of commercial dance music, which required danceable tempos, familiar tunes and vocal numbers, and the ambitions of players and arrangers who wanted to develop extended composition and personal expression.
By the early 1940s, the big band economy was under strain. Touring large ensembles was expensive, the draft and wartime conditions reduced the number of available players, and the American Federation of Musicians recording ban of 1942–1944 interrupted the documentation of the music. These pressures, together with changing tastes, shifted attention toward singers and smaller groups and set the stage for the changes of the mid-1940s.
Bebop (1940s)
Minton's Playhouse and the after-hours laboratory
Bebop grew out of late-night jam sessions in Harlem, most visibly at Minton's Playhouse in New York City. Henry Minton hired former bandleader Teddy Hill as house manager in 1940, and the club became the central laboratory for the new music. Hill assembled a house band led by drummer Kenny Clarke, with Thelonious Monk as the house pianist. The owner's union connections also mattered: because of these ties, musicians could take part in jam sessions without being fined, an activity the union otherwise prohibited.
The sessions also worked as a filter. Players used very fast tempos and chords that were considered strange at the time, which eliminated those who were not sufficiently advanced. Guitarist Charlie Christian was among the early contributors; he played nightly at the club before dying of tuberculosis in March 1942, at a sanatorium, having been in his mid-twenties in 1941.
Key figures and the new harmonic language
The partnership at the core of the style was between alto saxophonist Charlie Parker and trumpeter Dizzy Gillespie. The two met in Earl Hines' big band in 1943, and both later played in Billy Eckstine's big band before striking out on their own. Gillespie was one of several regulars who shaped the sound, along with Parker, Christian, Monk and Max Roach. Monk's harmonies were a counterpart to the angular, asymmetrical lines of Parker and Gillespie.
Musically, bebop pushed harmony and tempo further than swing had. Its players built melodies on dense chord changes, often with altered chords and extended harmony, and played them at speeds that demanded exceptional technique. Their vocabulary also drew on unconventional chromaticism, discordant sounds, and displacements of accents in melodies. Recordings such as Gillespie and Parker's "Koko" (1945), Parker's "Ornithology" (1946) and Monk's "'Round Midnight" (1947) show these features clearly.
From dance floor to listening room
Bebop marked a break with the commercial dance music of the big bands. Britannica notes that the style moved jazz away from dance music toward a more intricate, listening-focused art form. The fast tempos and complex harmony made the music hard to dance to, and the form became more suited to concert halls and attentive audiences. Gillespie's compositions, such as "Woody 'n' You," became bebop standards and were later recorded widely. The Billy Eckstine Orchestra, which formed in 1944 and is considered the first bop big band, showed that the new idiom could also work in a larger ensemble.
The 1942–1944 recording ban
The development of bebop coincided with a labor dispute that kept most of it off record. Beginning at midnight on July 31, 1942, no union musician could make commercial recordings for any commercial record company. The ban, called by the American Federation of Musicians under president James C. Petrillo, was a dispute over royalty payments. Live performances were not covered: the strike did not affect musicians performing on live radio shows or in concerts.
The effect on documentation was significant. Decca settled first, in September 1943. RCA Victor and Columbia held out until November 11, 1944, more than two years after the ban began. As a result, the period when bebop was taking shape is poorly represented in studio recordings. Surviving material from the early 1940s comes largely from live broadcasts and private recordings, such as the 1941 tapes made by a Columbia University student. When studio recording resumed, the first bebop session to be documented was in 1944 and included Gillespie's "Woody 'n' You" with Coleman Hawkins. The settlement also coincided with the rise of independent labels, which helped preserve and disseminate the new style.
World War II also shaped the period's economics and labor relations, since the strike began only months after the United States entered the war. The strike's effect on the bebop repertoire, and the question of how much of the early style went unrecorded, remain subjects of historical study.
Cool, West Coast and hard bop (late 1940s–1950s)
Cool jazz
In September 1948, a nine-piece group led by trumpeter Miles Davis held a two-week booking at New York's Royal Roost, sharing the bill with Count Basie's orchestra. Davis was able to secure a two-week engagement in September 1948 for the nonet opening for Count Basie at the Royal Roost in New York. The group's repertoire came out of a circle of arrangers. A regular gathering of like-minded musicians at arranger Gil Evans' Manhattan apartment provided the workshop where the ensemble's ideas took shape. Sources disagree on the division of labour. One account credits Mulligan contributed six arrangements, Lewis three, Evans two to the book, while another says Mulligan wrote nine of the twelve recorded arrangements.
Capitol Records took an interest after Pete Rugolo, who signed the group to record for Capitol, attended one of the Royal Roost shows. The recordings were made over three sessions over nearly a year and a half. The first session took place on January 21, 1949, and the last on March 9, 1950. The sound was distinctive for the period. The ensemble placed a French horn among its horns, and the instrumental lineup was constant excepting the omission of piano and the addition of Kenny Hagood on March 9. The arrangements drew on techniques such as polyphony from classical music. Critics later described a hip, detached elegance, never getting too hot, even as the rhythms skip and jump. Capitol issued the material as the LP Birth of the Cool in 1957. Its early reception was lukewarm, and despite the chilly reception by audiences of 1949, the Davis nine-piece was later reappraised as one of the most influential groups in jazz history.
West Coast jazz
The style that came to be called West Coast jazz developed in California in the early 1950s, although its roots lay with the New York nonet. The sound, despite its East Coast origins, became known as West Coast Jazz. The scene centred on Los Angeles and San Diego, where clubs, recording studios and small labels supported a lighter, arranged approach. Chet Baker's partnership with Gerry Mulligan's piano-less quartet, which recorded for Pacific Jazz in the early 1950s, and Dave Brubeck's quartet, based in California, are among the best-known examples of the style. The Los Angeles jazz community also included Shorty Rogers and Shelly Manne, whose work reflected the cool aesthetic.
Hard bop
Hard bop emerged as a more emotionally direct reaction to cool jazz. Journalists and record companies began using the term in the mid-1950s to describe a new current within jazz that incorporated influences from rhythm and blues, gospel music, and blues, especially in saxophone and piano playing. The pivotal group was built around drummer Art Blakey and pianist Horace Silver. With Horace Silver, Blakey founded the Jazz Messengers (1954), toured Europe, and recorded (1955–61) a brilliant string of records for the Blue Note label. Accounts differ on the starting date, with some placing the partnership in 1953. The 1954 Birdland recording established the blueprint for that particular new sound and style, according to one account. Silver's composition "The Preacher," recorded in 1955, was one of the first definitive hard bop compositions. Silver departed in 1956, leaving Blakey at the helm. Under Blakey, the group continued to record for Blue Note, and the album Moanin', recorded in 1958, is often cited as the peak of that output. The trumpeters and saxophonists of the era, including Clifford Brown and Lee Morgan, brought more blues inflection and a darker, warmer tone to the horn sound.
Soul jazz and the Hammond organ
Soul jazz developed alongside hard bop, and the Hammond B-3 organ was central to its sound. Gospel and blues shaped the style. Smith was influenced by both gospel and blues. Organists had played jazz before him. Fats Waller, Count Basie, and Wild Bill Davis all preceded him, but he was the first notable practitioner of the Hammond B3 and gave the instrument credibility within a jazz setting. The instrument had been originally marketed towards churches as a cheap alternative to pipe organs, and musicians such as Smith adopted it for its jazz potential. In 1951, Smith stumbled upon the B-3 Hammond organ, which had been introduced a few years prior.
Blue Note Records was decisive in documenting the style. In early 1956, Smith got his big break when Blue Note co-founder Alfred Lion heard him play in a club. With Blue Note issuing five LPs under Smith's name in quick succession during 1956 alone, his popularity grew rapidly. His 1959 album The Sermon! is among the most cited records of the period. Its personnel linked the organ style to the hard bop circle, since he's joined by Burrell and now by drummer Art Blakey. Blue Note's catalogue of the period had other key artists, including Art Blakey, Horace Silver, Lee Morgan, Hank Mobley, Clifford Brown, Freddie Hubbard, Kenny Burrell, Grant Green, and Jimmy Smith.
Modal jazz and free jazz (late 1950s–1960s)
Modal jazz
Modal jazz took the scale or mode, rather than a run of chord changes, as the basis for improvisation. The theory behind it came mainly from George Russell. Russell's Lydian Chromatic Concept of Tonal Organization offered an alternative to chord-based improvisation. It set out a principle of chord/scale unity and was the first theory to examine the vertical relationship between chords and scales. The book first appeared in 1953 and is often described as the first theoretical contribution to come out of jazz.
Davis was the first to test these ideas on record. Inspired by Russell, he wrote his first modal piece, the title track of the 1958 album Milestones, and after hearing the results he planned an entire album built on modality. The sessions for that album, Kind of Blue, began in March 1959. The practical difference lies in the harmony. When the rhythm section holds one harmony for a long stretch, a soloist can draw on the whole scale rather than being confined to the chord tones that a changing progression would demand. Pianist Bill Evans worked with the same theory on the same record, and Evans and Davis used the theory to record modal jazz, such as the album Kind of Blue.
John Coltrane was among the other principal exponents of modal playing in these years, extending the approach in his own quartet work and in his later music.
Free jazz
Free jazz went further by dispensing with fixed harmony and, in many performances, with a steady meter. Its most important early statement was Ornette Coleman's The Shape of Jazz to Come. Released on Atlantic Records in November 1959, it was Coleman's debut on the label and his first album with a quartet of himself, trumpeter Don Cherry, bassist Charlie Haden, and drummer Billy Higgins. Like the quartet of Gerry Mulligan, Coleman's group had no chordal instrument such as piano or guitar, which removed a conventional source of harmonic support. The typical structure was a brief statement of the theme, several minutes of free improvisation, and then a return to the main theme. Critics treated it as the most prominent early free jazz record, even though the term had not yet come into use when it appeared. Coleman's "Lonely Woman" later became a standard and was cited as an important early work in free jazz.
Other musicians pursued different routes. Cecil Taylor built a percussive, densely clustered piano style that treated the instrument almost as an orchestra, while Albert Ayler favoured simple, hymn-like or folk-like melodies played with a rough, vibrating saxophone tone. Both worked outside conventional harmony, but their music was far from uniform.
Coltrane's late work
Coltrane's A Love Supreme was recorded in one session on December 9, 1964, at Van Gelder Studio in Englewood Cliffs, New Jersey, with a quartet featuring pianist McCoy Tyner, bassist Jimmy Garrison, and drummer Elvin Jones. The album was released in January 1965 on Impulse! and is usually classed as spiritual and modal jazz. Coltrane described the four-part suite in its liner notes as a thank-you to God. Its four sections are titled "Acknowledgement," "Resolution," "Pursuance," and "Psalm," and it can be said that they form or follow the path to enlightenment. Commentators disagree about how far the spiritual content shaped the music itself. How spiritual Coltrane was, and how much this fed into his music, is still debated today. Archie Shepp, who played tenor on alternate takes of "Acknowledgement," described the album as a work that confirmed Coltrane's connection to the Afro-American church. The album has been seen as proof that jazz could serve as a fitting medium for spiritual exploration.
The avant-garde in Chicago and the Black Arts Movement
In Chicago, the Association for the Advancement of Creative Musicians (AACM) was founded in 1965 by pianist and composer Muhal Richard Abrams and others. Its members, including Roscoe Mitchell, Anthony Braxton, and Lester Bowie, promoted original composition, self-directed presentation, and the collective ownership of musical projects, and their work led to groups such as the Art Ensemble of Chicago. The AACM's aims overlapped with the Black Conscious movement of the 1960s, the period that also saw the assassination of Malcolm X. Writers and artists associated with the Black Arts Movement argued that Black art should speak to Black communities and serve their political goals, and many avant-garde jazz musicians shared that outlook. The links between free jazz and the wider modernist avant-garde, as well as its position within African American cultural politics, remain a central topic in the scholarship on this period.
Jazz-rock and fusion (late 1960s–1970s)
Fusion, also called jazz-rock, grew out of Miles Davis's move toward electric instruments in the late 1960s. His album In a Silent Way (1969) introduced the electric sound, and Bitches Brew, recorded in August 1969 and released in March 1970, carried it further. Davis used electric piano and electric guitar, and he set aside the swing-based rhythms of acoustic jazz in favour of looser, rock-influenced grooves built around improvisation. Few sources describe the session as a conventional studio date. Davis gave the musicians sketches and a chord centre rather than written parts, and several players, including two bassists and multiple drummers, performed together. Producer Teo Macero then edited the long takes into the final double album. The record drew mixed reviews at first, but it later became Davis's highest-charting album in the United States, reaching No. 35 on the Billboard 200, and it won a Grammy in 1971. Although it was not the first jazz record to mix rock and jazz, it is usually treated as the work that defined the fusion idiom.
Several groups formed around the musicians who had worked with Davis. Weather Report, co-led by the Austrian keyboardist Joe Zawinul and the saxophonist Wayne Shorter, was founded around 1970, though accounts of its origins differ. Its early recordings stressed collective improvisation and blurred the line between soloist and accompanist, and its style later moved toward more structured, groove-based pieces such as "Birdland" (1977). The Mahavishnu Orchestra, formed in 1971 by the guitarist John McLaughlin with the drummer Billy Cobham and the keyboardist Jan Hammer, combined rock volume and energy with asymmetric time signatures, Indian classical rhythmic ideas and, in McLaughlin's case, a twin-neck guitar. Return to Forever, led by Chick Corea from 1972, moved from a Latin-influenced acoustic sound to a harder electric style that also drew on progressive rock. These three groups, together with Herbie Hancock's Headhunters, are generally regarded as the leading fusion bands of the early 1970s.
Rock, funk and rhythm and blues shaped the fusion sound in different ways. Hancock's album Head Hunters, released by Columbia in October 1973, is the clearest example of the funk turn. Hancock had worked in the avant-garde with Davis and on his own records, but on this album he built deeply funky rhythms, drawing on Sly Stone, Curtis Mayfield and James Brown, and played soloists on the Fender Rhodes electric piano and synthesizers. The record's grooves were rooted in funk, soul and rhythm and blues, while its long improvised passages kept it within jazz. Hancock's reliance on synthesizers and the Rhodes made the instrument central to the sound of the period. Several sources report that Head Hunters became a major commercial success and the first jazz album to reach platinum status, although the exact claim is reported by only some sources.
Fusion's commercial reach was matched by a sharp division of opinion. Its audiences were larger than those for many acoustic jazz records, and it reached rock listeners and young funk audiences. Many jazz purists regarded the use of amplified instruments, rock beats and funk grooves as a betrayal of the tradition, and critics were often divided over whether the music advanced jazz or diluted it. Some established players, including Davis, were nonetheless associated with the movement, and the division between fusion's popularity and its reception among specialists remained a continuing point of debate through the 1970s.

Latin, Brazilian and European exchanges
Afro-Cuban jazz
The sustained fusion of jazz with Cuban music is usually dated to New York in the 1940s. Trumpeter Mario Bauzá, born in Cuba, had played in swing orchestras in the 1930s, where he and Dizzy Gillespie grew close, shared a trumpet section, and toured together. In 1939 Bauzá helped found Machito and his Afro-Cubans, and in 1941 he became the group's musical director. Bauzá's composition "Tanga," recorded in 1943, is often cited as the first piece to combine jazz harmony and arranging, improvised soloists and Afro-Cuban rhythm, with the clave rhythm as an organizing principle. Bauzá had also shown Gillespie how Afro-Cuban polyrhythms, in which bass, percussion and clave interrupt the steady flow of swing.
Gillespie's later partnership with the Cuban percussionist Chano Pozo made the hybrid widely known. In 1947 the two brought Afro-Cuban rhythms and instruments such as the tumbadora and the bongo into the East Coast jazz scene. Their music was labelled "Cubop," short for Cuban bebop, and their "Manteca" became a standard of the jazz repertoire. The style's early centre of gravity was in the United States: during its first decades, the Afro-Cuban jazz movement was stronger in the United States than in Cuba. Machito's sound also influenced white bandleaders; Stan Kenton began experimenting with big-band jazz and Afro-Cuban percussion, leading to recordings of "The Peanut Vendor" and "Cuban Carnival" in 1947. The partnership continued into the 1970s, when Gillespie and Machito recorded the album Afro-Cuban Jazz Moods, with arrangements by Chico O'Farrill, in 1975.
The mambo, which grew out of Cuban dance orchestras and became a popular dance craze in the United States during the 1950s, drew on the same interlocking brass riffs over a clave-based rhythm section. Its percussion pattern of congas, timbales, bongos and bass became a standard component of the Latin rhythm section that jazz groups adopted.
Brazilian bossa nova
Bossa nova, which developed in Rio de Janeiro in the late 1950s, reached North American listeners largely through jazz musicians. Saxophonist Stan Getz had already sparked a bossa nova craze in 1962 with Jazz Samba, his album with American guitarist Charlie Byrd.
The decisive meeting came with Getz/Gilberto. The album was recorded on March 18–19, 1963 and released by Verve in March 1964, pairing Getz with the Brazilian singer and guitarist João Gilberto. Antônio Carlos Jobim wrote most of the songs on Getz/Gilberto and played piano on the sessions. The recording's most famous track, "The Girl from Ipanema," featured Gilberto's wife Astrud, who had no professional experience as a singer, and the song won a Grammy for Record of the Year in 1965. The album also made "Corcovado" and "Desafinado" standards. Bossa nova's understated aesthetic had itself been influenced in part by cool jazz, so the exchange ran in both directions. The collaboration continued in concert: as a result of the album's success, the Brazilian Gilbertos and the American Getz played a number of shows in the U.S., including a Carnegie Hall performance in October 1964.
European jazz
European jazz developed its own identity earliest in France. Django Reinhardt, a Romani guitarist born in Belgium in 1910, and the violinist Stéphane Grappelli founded the Quintette du Hot Club de France in Paris in 1934. The group grew out of a series of backstage jams at the Hôtel Claridge on the Champs-Élysées, where the two were working in a band led by the bassist Louis Vola.
The Quintette's instrumentation set it apart from American ensembles. Its lineup was all strings, with the lead parts played by acoustic guitar and violin, a double bass in place of the tuba or sousaphone, and no drummer. The two rhythm guitarists supplied both harmony and a percussive pulse, which allowed the band to produce its rhythmic drive without drums. The group's style, often called gypsy jazz, draws on Romani music and has its origins in France and among the Manouche clan of Romanis, where it has remained popular. The group was active in one form or another until 1948, and Grappelli and Reinhardt also worked with French popular singers, which kept the Quintette connected to song-based repertoire. Reinhardt died in 1953, and Grappelli spent much of the war in London. Elsewhere in Europe, jazz developed distinct regional idioms, shaped by local dance traditions, languages and the availability of recordings.
Forms, repertoire and instrumentation
Repertoire and the standard
Most of the material jazz musicians improvised on came from outside the genre. Fueled by Tin Pan Alley, Broadway shows, and Hollywood movies, composers and lyricists, among them Cole Porter, the Gershwins, Rodgers and Hart, Jerome Kern and Harold Arlen, wrote songs that became standards. The repertoire known as the Great American Songbook has no fixed list, but its core is usually taken to include Irving Berlin, the Gershwins, Porter, Kern, Harold Arlen and Rodgers, along with a broadly agreed core of at least several hundred songs. The phrase itself was popularized by singer Carmen McRae, whose 1972 album, The Great American Songbook helped fix the name. Critic Ben Yagoda has put the output of the 1920s to the early '50s at roughly 300 to 400 standards.
A standard works as a shared language because it can be played and interpreted again and again, by different performers in creative ways. Since most players knew these tunes, they could join a session without rehearsal. Jazz musicians often treated the melody as a starting point and reshaped harmony, rhythm and tempo around it.
Lead sheets, fake books and the Real Book
Working players rarely read full arrangements. A lead sheet gives the melody, chord symbols and sometimes lyrics, and the performers supply the rest. Given just the basic melody and chords, a musician or band can create a complete, polished-sounding performance that includes intros, solos, backgrounds and codas. Collections of such charts were called fake books, a name that refers to trained jazz performers being able to improvise accompaniments and solos from chord charts. An early precursor was the Tune-Dex card system, first issued in May 1942 on index cards.
Most fake books were unlicensed. Fake books originally infringed copyrights, and their circulation was primarily underground. The best-known example, the Real Book, was compiled in the mid-1970s by students at Berklee College of Music, and it quickly became the standard among jazz musicians. Its unlicensed origin also explains why later editions were licensed; the first Real Book was illegal as it infringed copyrights. More recent commercial editions are legal.
Common forms
Jazz drew on a small number of forms. The twelve-bar blues and the thirty-two-bar AABA song form, with its two eight-bar A sections, a contrasting B section and a return to A, were the standard frames for both Tin Pan Alley songs and jazz performances.
A contrafact is a musical composition consisting of a new melody overlaid on a familiar harmonic structure. The most important example is "rhythm changes," built on the chord progression of George Gershwin's "I Got Rhythm," first heard in 1930. The chord changes began to be used in the 1930s, became common in the '40s and '50s, and are now ubiquitous. The earliest known use is Sidney Bechet's September 15, 1932 recording of "Shag". Charlie Parker's bebop tunes, such as "Anthropology" and "Moose the Mooche," made the progression central to modern jazz. Contrafacts also had a practical side: while melodies can be copyrighted, the underlying harmonic structure cannot be, so musicians could write new melodies over familiar changes without paying publishers. Because the progression was stable and widely known, almost all jazz contrafacts leave off the tag, making 'rhythm changes' a basic, 32-bar form.
Instrumentation
Instrumentation changed with the forms. Early New Orleans ensembles typically combined cornet or trumpet, clarinet and trombone in front, with a rhythm section of banjo or guitar, tuba or string bass and drums. The swing big bands expanded this into sections of saxophones, trumpets and trombones. Later small combos settled on a front line of one or two horns, often saxophone or trumpet, supported by piano, double bass, drums and sometimes guitar.
Vocal jazz developed alongside these groups. Singers reinterpreted the standards with improvised phrasing, and after the big band era jazz singers, like Ella Fitzgerald and Carmen McRae, were among those who kept the songs alive.
Recording, media and the business of jazz
Independent labels and the documentation of new styles
Much of what survives of early and mid-century jazz depends on a small number of record labels. Founded in 1939 by Alfred Lion, who had only arrived in America a few years earlier had fled the oppressive Nazi regime in his native Germany, Blue Note became one of the best-known examples. Lion's first session for the label was set up in New York in January 1939 with pianists Albert Ammons and Meade Lux Lewis, after he had assured the two pianists that they would be paid.
Blue Note's reputation rested on working practices as much as on repertoire. Lion and Wolff quickly established a reputation for being reputable businessmen who encouraged creativity in the studio and paid their musicians well (they even paid for rehearsal time, which was not a standard practice at most record companies at the time). Francis Wolff, the co-owner, also photographed sessions and clubs, and over the next three decades he documented jazz history as it happened. Engineer Rudy Van Gelder and designer Reid Miles completed the label's visual and sonic identity, which made its records easy to recognise.
Independent companies were often willing to back artists that larger firms avoided. Blue Note recorded Thelonious Monk in 1947 when other labels had declined to, and it kept him under contract for several years although his records sold poorly. John Coltrane, Art Blakey, Miles Davis, Dexter Gordon, Herbie Hancock, Bud Powell, Sonny Rollins, Horace Silver, for starters, and they all laid down some of their most timeless tracks for the label. The label is now part of the global music industry: Blue Note Records is an American jazz record label now owned by Universal Music Group.
Major companies also shaped the record for jazz. Columbia Records issued Duke Ellington's film score discussed below, and later labels such as Verve, Impulse! and ECM built distinct catalogues of their own. Each label's choices about studios, producers and sleeve design influenced which versions of a style reached listeners.
Festivals, clubs and broadcast
Live performance remained central to how jazz reached audiences, and festivals became a major outlet from the 1950s. The Newport Jazz Festival began in Rhode Island in 1954. Elaine Lorillard established the festival in 1954, and she and husband Louis Lorillard financed it for many years. They hired George Wein to organize the first festival and bring jazz to Rhode Island. The debut took place on July 17 and 18, 1954, at Newport Casino, and an estimated 13,000 people came to the two-day festival. Critic Leonard Feather later argued that the event opened what he called the "festival era" in American music. The festival remained in Newport until 1971, when it was moved to New York City.
Nightclubs, dance halls and touring circuits remained the working base for most musicians, while radio and jukebox play carried recordings to listeners who never saw a band. Festivals, by contrast, concentrated audiences and critics in one place, and their programming often set reputations.
Film and screen music
Jazz also entered film, where composers had to fit music to a dramatic structure. Duke Ellington's score for Anatomy of a Murder (1959) is a notable case. By 1959, Duke Ellington had appeared in several films with his orchestra, but had never been commissioned to write a film score. Director Otto Preminger's offer led him to compose for the picture, and recorded in May and June 1959, Ellington's score was the first time he had to write to the structural requirements of another's film. Duke recorded the score twice, once for Columbia Records and then again for Columbia Pictures. The recorded score featured his full big band (and a small group culled from the band), and it was a jazz score throughout, even though jazz only played a tangential role in the film's storyline. The soundtrack album later won three Grammy Awards in 1959. One album note also describes the score as the first non-diegetic music made by African Americans for a major film, a claim that reflects that source's own framing.
Money, unions and working conditions
For most players, income came from live engagements, dances and touring, with recording fees and royalties forming a smaller and less predictable share. Questions of contract terms, publishing rights and ownership of masters recurred throughout the history of the music, and they tied jazz to wider debates over intellectual property and copyright. Club owners and promoters controlled much of the work available, which left musicians dependent on a small number of venues and employers.
Education and transmission
For most of its history, jazz was learned outside formal institutions. Young players typically apprenticed with older musicians on the bandstand, on the road and in after-hours clubs, absorbing repertoire, phrasing and stage conduct by listening and playing. The jam session was the main proving ground. A newcomer could sit in over the changes, and the informal "cutting contest," in which soloists tried to outplay one another, tested technique and reputation at once. Recordings of major soloists served as a second teacher: players transcribed solos by ear and copied them note for note, a practice that remained central to learning the idiom. In this sense the music was transmitted through oral tradition as much as through notation.
The move into institutions began with private schools. MIT graduate Lawrence Berk founded Schillinger House, the precursor to the Berklee School of Music, after quitting his job at Raytheon. At a time when almost all music schools focused on classical music, Schillinger House offered training in jazz. The school later grew into the largest independent school of music in the world. Its teaching methods were also innovative. In 1957 Berk introduced a series called Jazz in the Classroom, featuring recordings of big band arrangements and performances by the school's best students, packaged with copies of the arrangements. This combined recording, score and performance into a single package for teachers and students.
University programs spread more slowly, but steadily. The first college degree in jazz was offered in 1947 at the University of North Texas. In the 1950s, over 30 colleges and universities added jazz courses to their curricula, and by 1982 the number of institutions offering a degree in jazz studies had reached 72. Key figures shaped this growth. David Baker, who founded the Jazz Studies program at Indiana University in 1966, was among the first to codify the largely aural tradition of jazz in print. Starting around the 1960s, the music's advocates increasingly turned to institutions of higher education. Within a few decades, college campuses became an unavoidable part of the modern jazz world. The New England Conservatory's Afro-American Music department, which opened in 1969, began to provide training that focused more on small group improvisation. Later programs followed, such as the first Bachelor of Music degree in Jazz Studies in North Carolina, at North Carolina Central University in 1979, and the Louis Armstrong Jazz Performance Program at Columbia University, founded in 2001.
Academic study has also changed what is taught. Berklee, in particular, became a hub for teaching jazz and popular music theory, arranging and performance. Degree programs now divide the field into areas such as instrument study, ensemble playing, history and theory. A typical jazz major must master history, theory, and performance, all at equally high levels of competence. Graduate programs add jazz composition, jazz pedagogy, jazz ensemble development, which shows how teaching itself has become a subject of study. Improvisation is treated as a skill that can be analysed, practised systematically and assessed. Method books, play-along recordings and transcription anthologies support this approach, and their use raises a recurring question: how to preserve the stylistic foundations of an aurally learned music while treating it as an evolving art form that extends beyond its African-American origins.
Secondary education and community programs form the base of this system. Student big bands and stage bands train many players before they reach college. In 1969, Lee Eliot Berk founded the first New England High School Stage Band Festival, later known as the Berklee High School Jazz Festival. By 2010 it had grown to become the largest event of its kind in the United States. Cultural institutions such as Jazz at Lincoln Center also run educational programs for students and teachers, linking performance practice with classroom instruction.
Neo-traditionalism, smooth jazz and the late twentieth century
Neo-traditionalism took shape in the early 1980s around the trumpeter Wynton Marsalis. Marsalis settled in New York in 1979, and within a year Art Blakey's hard bop ensemble, the Jazz Messengers, had invited him to join. His self-titled 1982 Columbia debut was produced by Herbie Hancock, and the Los Angeles Times described the record as "the birth point of the Re-bop Renaissance." The movement's core claim was that acoustic, swing-based playing in the lineage of bebop and hard bop was the authentic form of the music. In Marsalis's view, "true" jazz rested on swing, acoustic sound, tonality, craftsmanship and knowledge of the tradition. Its proponents set themselves against electric fusion and the avant-garde, and they rejected the rebellious counterculture linked to the bebop generation. Marsalis argued that jazz could attain "fine-art" status and be compared with classical music rather than with rock. Institutional weight followed in 1987, when Murray, Crouch and Marsalis founded Jazz at Lincoln Center in New York, which became one of the main promoters of the neotraditionalist movement. Supporters credited the movement with renewing interest in acoustic repertoire and expanding education, while critics argued that it stifled innovation by prioritizing tradition over experimentation.
The smooth jazz format grew from commercial radio rather than from the bandstand. It began in the 1980s as "adult alternative" or NAC, a well-defined radio format that combined jazz, new-age music and adult contemporary music. A major shift came in 1987, when the album-oriented rock station KMET in Los Angeles switched to KTWV "The Wave," which made the format more popular. The label itself is usually traced to market research: at a focus group in Chicago run by Broadcast Architecture, the firm that first sold radio stations on the new format in the early 1990s, a participant blurted out "smooth jazz." Musically, the style described a jazzlike sound without the improvisation that is essential to jazz, with melody-driven songs played mostly on instruments used in jazz. Its audience was built around office workers and commuters, and programmers assembled a mix of fusion ingredients, light R&B, pop balladeers and a few straight-jazz artists. Saxophonist Kenny G became the format's best-selling figure, selling unprecedented numbers of albums for a jazz artist while receiving airplay on practically every smooth jazz station. The format's success was commercial and critical in a divided way. Critics dismissed it as the elevator music of the '90s, but stations generally did well, and around 2007 the format lost popularity, and several high-profile stations abandoned it.
The M-Base collective emerged in the mid-1980s as a counterpart to neo-traditionalism. The term "M-Base" was coined in the 1980s by the alto saxophonist Steve Coleman to describe a theory of creative expression. Coleman's group Five Elements released On the Edge of Tomorrow in January 1986, a manifesto of non-Western musical thinking that showed little regard for conventional time signatures. The collective was associated with a loose group of young African American musicians and other performers active in and around Brooklyn, New York, and its members included Graham Haynes, Cassandra Wilson, Geri Allen, Robin Eubanks and Greg Osby. Their music re-imagined the grooves of funk and soul within traditional and avant-garde jazz, drawing on the lineage of the AACM and Black Artists Group. Rhythmically, Coleman's work used multi-layered rhythmic cycles, more or less inspired by West African music, with different instrumentalists playing in different meters. Coleman resisted the label, insisting that "M-Base" denoted a way of thinking about creating music rather than a musical style. The collective's recordings culminated in the 1991 CD Anatomy of a Groove, recorded by a significant number of participants under the name "M-Base Collective."
Hip hop's relationship with jazz was shaped largely by sampling. Producers drew drum breaks, basslines and horn phrases from earlier jazz and soul records, which gave hip hop a direct link to the recorded past. Some jazz musicians responded by engaging with the new scene; the trumpeter Graham Haynes, for example, returned to New York City in 1993 to take advantage of the flourishing hip-hop scene, and the resulting album, Transition, was heavily sample-based. Sampling also raised questions about copyright and royalties, which were resolved through licensing and legal clearance, and these questions remain part of the exchange between jazz and hip hop producers.
Global and contemporary jazz (2000s–present)
Since the 2010s, London has become one of the most visible centres of new jazz. Commentators often treat Shabaka Hutchings as the central figure of the UK revival. Sons of Kemet was formed in London in 2011 by saxophonist and composer Shabaka Hutchings, and the group replaced the bass with a tuba and used two drummers. Its 2018 album Your Queen Is a Reptile, issued on Impulse!, was shortlisted for the Mercury Prize and placed first on The Wire's annual album list that year. The band was dissolved in 2022. Hutchings also served as music director of the compilation We Out Here on Gilles Peterson's Brownswood label, which brought many London players to wider attention. Among them, the Ezra Collective, whose members include Dylan Jones on trumpet, James Mollison on tenor sax, Joe Armon-Jones on keys and TJ Koleoso on bass, draw on grime production and house beats as well as conventional jazz models. Koleoso has argued that jazz rests on improvisation, engagement with its history, and the telling of a new story each time, a definition that lets the group's work count as jazz. The scene's commercial reach also grew: one of the London-based new jazz groups, Ezra Collective, sold out the 2,400-capacity Koko in Camden, and a Spotify report noted a 108% rise in listeners aged 30 and under to its Jazz UK playlist over a single year.
The wider fusion of jazz with hip hop and R&B has been driven in large part by Robert Glasper. A classically trained pianist, he moved from an acoustic trio toward the more electric, hip-hop-oriented Robert Glasper Experiment. He met neo-soul singer Bilal, who became a frequent collaborator and led him into the Soulquarians, a collective of hip-hop and neo-soul musicians. The group's Black Radio (2012) on Blue Note featured neo-soul and hip-hop guests such as Erykah Badu, Bilal, We Are King and Yasiin Bey. The album later made it to both the jazz and R&B charts and won the Grammy for Best R&B album, a rare honour for a jazz record. The sequel Black Radio 2 (2013) repeated the pattern, and Black Radio III (2022), released on Loma Vista, followed after Glasper had dissolved the RGE band.
Kamasi Washington's The Epic (2015) became the most widely discussed large-scale jazz release of its period. It was the third studio album by the American saxophonist and his first on a record label, released on May 5, 2015 by Brainfeeder. Its running time and forces were unusual: a 32-piece orchestra, a 20-strong choir and a 10-piece band producing a 172-minute, three-volume, 17-track suite. Critical reception was largely positive, with a Metascore of 83 based on seven critic reviews. Reviewers disagreed on its significance. The Guardian found that its lack of thematic surprises, given its length, kept it from being the seismically jazz-changing departure some admirers claimed, while Rolling Stone described it as a jazz album, as much about tradition as expanding it. Critics writing in the Brooklyn Rail read its warm reception as a sign of nostalgia culture more than of a new direction.
Beyond London and the United States, jazz has developed distinct regional scenes. Abdullah Ibrahim, born in Cape Town as Adolph Johannes Brand, left South Africa in 1962 under apartheid and became one of the most important South African pianists of the twentieth century; he returned home after the end of apartheid and continued to draw on South African musical traditions. Cuba, Japan and the Nordic countries have each produced musicians and audiences whose work reflects local idioms as well as the international language of the standard repertoire.
Digital distribution has changed how new jazz reaches listeners. In an age when music is dismissed within the first 15 seconds of a stream, a three-hour album feels like a relic from a time of patience and focus, one reviewer observed, pointing to the attention pressures of streaming services. Playlists, algorithmic recommendation and social media now shape which artists gain audiences, while reissues of older records, such as Blue Note's 2022 reissue of Black Radio as a tenth-anniversary edition, present earlier work to new listeners. Independent labels and small venues, from Brainfeeder to Brownswood, remain central to how this music is recorded and promoted.
Influence on other music and the arts
Popular music
Jazz's reach into popular music is broad. Swing-era horn riffs and rhythm-section grooves passed into rhythm and blues and early rock and roll, where saxophone-led jump bands carried jazz phrasing into mass-market records. In funk, the interlocking horn and guitar parts of James Brown's bands drew on the layered call-and-response textures of big-band and small-group jazz. A swing revival in the 1990s returned the jump and big-band sound to mainstream audiences. Hip hop producers later built beats from drum breaks and horn samples taken from jazz and soul records, and the sampling of jazz catalogues became routine. Projects that deliberately fused the two, such as Guru's Jazzmatazz (1993), made the connection explicit.
Classical music
Concert composers began absorbing jazz in the early 1920s. A 1922 visit to Harlem gave Darius Milhaud the material for La création du monde, a 1923 ballet that drew on African folk mythology and jazz idioms. French composer Milhaud heard jazz in Harlem during a 1922 visit and brought the sound back to Paris, and the ballet is often compared with the work that followed it. Milhaud's work predates the Gershwin classic by a year.
George Gershwin's Rhapsody in Blue became the most widely known example. Its first performance took place on 12 February 1924 at Aeolian Hall in New York, where Paul Whiteman's band performed the piece, with Gershwin playing the piano. The scoring includes saxophones and banjo, and ragtime rhythms are abundant, as well as Cuban "clave" rhythms. Later critics have not all celebrated the synthesis. Some scholars now see the work as a whitewashed version of Harlem's vibrant Black music scene. Igor Stravinsky, after his own time in America, regarded the idiom as something no serious composer could ignore.
Literature of the Harlem Renaissance and the Beat generation
The Harlem Renaissance of the 1920s and 1930s, a flowering of African American writing, gave jazz a literary setting. Langston Hughes is credited as the father of jazz poetry, a literary genre influenced by or sounding like jazz, with rhythms and phrases inspired by the music. His poem "The Weary Blues", written in 1925, describes a pianist playing blues in a Harlem bar. The collection that followed was published by Knopf in 1926, and it aimed to depict Harlem nightlife by blending "traditional poetic forms with vernacular speech and jazz rhythms".
Later writers extended this relationship. Jack Kerouac's theories of spontaneous prose borrowed the logic of bebop improvisation, and poets of the Beat generation often performed their work with jazz accompaniment in San Francisco and New York clubs. The poetry-and-jazz format allowed spoken text to take on the pacing and phrasing of a soloist.
Visual arts
The painter and collagist Romare Bearden is often described as the consummate jazz painter. He moved his studio to the Apollo Theater building in 1941, placing him in the middle of Harlem's music scene. Bearden described his method in musical terms. He often spoke of his work in musical terms, describing collage as akin to jazz improvisation. In one remark he put it directly: "You do something, and then you improvise."
His 1981 series of nineteen collages, often called Paris Blues or Jazz, is the fullest statement of this approach. The series moves through Paris, New Orleans, and Harlem, mapping jazz onto city spaces. The project began as a response to the 1961 film Paris Blues, as a planned oversized book, and while the book was never completed, the collages stand as a testament to this expansive vision. The collage medium itself traces back to modernist experiment, since collage had been part of cubism, which proved to be a reverberating influence throughout the 20th century.
Institutions, honors and cultural recognition
Institutions
Institutional support for jazz in New York came late and reluctantly. In a 1986 report, Lincoln Center said that no compelling case could be made for adding a constituent in an area like jazz. The breakthrough came when Alina Bloomgarden, a visitor-services director, proposed a summer concert series, and Wynton Marsalis helped plan it. Marsalis was involved in starting the Classical Jazz concert series in 1987, the first series of jazz concerts at Lincoln Center, which began in August of that year. The organization that grew from it, Jazz at Lincoln Center (JALC), was inducted as a constituent of Lincoln Center in July 1996, the first new constituent since the School of American Ballet joined in 1987. Its resident big band, the Jazz at Lincoln Center Orchestra, was formed the following year, in 1988.
Its physical home followed a decade later. Under Marsalis's direction, JALC commissioned the architect Rafael Viñoly and a team of acoustic engineers to create Frederick P. Rose Hall, described as the world's first performance, education and broadcast facility devoted to jazz. The building opened in 2004 as part of Lincoln Center. JALC's programmes are organised around four functions, educational, curatorial, archival and ceremonial, which together cover concerts, school instruction, recording and the annual award events that honour performers.
Congressional recognition
The clearest official acknowledgment of jazz in the United States came in 1987 through a concurrent resolution, H.Con.Res.57. It was introduced on March 3, 1987, sponsored by Representative John Conyers of Michigan. The House passed it unanimously on September 23, and both chambers had agreed to it by December 4, 1987. Because a concurrent resolution is not signed by the president and does not carry the force of law, the measure expressed the sense of Congress rather than creating any legal status or funding. Its operative language called jazz a rare and valuable national American treasure to which we should devote our attention, support. The bill's wider findings described jazz as an indigenous American music and art form rooted in the African-American experience, and as a force that bridged cultural, religious, ethnic and age differences. Conyers himself framed the vote as the first time the government had formally recognised the art form. Supporters' hopes for practical effects were uncertain at the time, but the resolution became a reference point for later congressional jazz resolutions and for the advocacy of the Congressional Black Caucus.
Other honours are institutional rather than legislative. Wynton Marsalis received the Pulitzer Prize for Music in 1997, a prize that brought a jazz composition into the category previously reserved for concert works. The National Endowment for the Arts' Jazz Masters programme, established in 1982, names living artists as lifetime fellows and funds related educational and archival activity. The Smithsonian Institution maintains jazz materials in its national museums and archives, which serve as public reference collections for researchers and listeners.
Cultural diplomacy during the Cold War
The United States also used jazz abroad. Congressman Adam Clayton Powell Jr., who had close ties to the jazz community, first proposed sending jazz musicians on state-sponsored tours in 1955. In March 1956, the State Department enlisted Dizzy Gillespie as America's first jazz ambassador, and his band played in southern Europe, the Middle East and South Asia. Although the tours were meant to promote American democracy and culture, they were also a response to Soviet claims about racism in the United States. By sending bands made up of black and white musicians to play together, the State Department could project an image of racial harmony to counter criticism of segregation at home.
The programme grew over the following decade. Sources differ on the total number of tours, but they agree that the programme was large and long-lasting. From 1956 through the late 1970s, America sent its leading jazz musicians to countries from Iraq to India, from the Congo to the Soviet Union. A notable milestone came in 1962, when Benny Goodman and his mixed-race band toured the Soviet Union, the first time the Russians permitted a foreign jazz band to tour the region. Not every tour proceeded as planned. In 1957, Louis Armstrong cancelled a planned State Department tour of the Soviet Union in protest against the Little Rock crisis. Duke Ellington's tour of the Middle East and India was cut short by the assassination of President Kennedy, and the programme was scaled back afterwards.
Historians have read these tours as a paradox. The musicians often used their platforms to speak about racial injustice, and audiences did not always equate enjoying jazz with supporting American foreign policy. Although it was intended as a colour-blind promotion of democracy, the strategy unintentionally showed how central African Americans were to American national culture.
Scholarship, debates and open questions
Scholars and critics have never agreed on where jazz begins and ends. One camp treats jazz as a coherent tradition held together by shared traits, while another sees the word as a loose label for many musics. Joachim-Ernst Berendt proposed a broad definition that stressed a distinctive relationship to time, which he called swing, and the meeting of African American and European musical practice. Travis Jackson offered a looser set of qualities, including swing, improvisation, group interaction and the cultivation of an individual voice, rather than a fixed list of rules. Krin Gabbard argued that "jazz" names a set of related musics that share enough to be read as one lineage. Dictionaries reflect the same tension: they define the term as a New Orleans-born music with improvised solos, and they also keep a separate sense for the large-band dance music of the 1920s. The boundaries with blues and rock are contested mainly in the case of jazz-rock, funk-inflected groups and, more recently, electronic music and world music. Duke Ellington's remark that all music is one category is often cited against strict borders, while purist critics have used the idea of swing to exclude later styles.
Questions of authorship and evidence form a second area of dispute. Early jazz was transmitted orally and only partly notated, so the first commercial discs have acquired an outsized role in arguments about priority. The Original Dixieland Jazz Band, a group of white musicians from New Orleans, issued the first jazz recordings in 1917, yet many historians argue that Black New Orleans musicians had developed the style for years before, and that the recording industry's choices shaped the story. Buddy Bolden, often named as an originator, left no recordings, so his reputation rests on the recollections of other musicians. Jelly Roll Morton's 1938 interviews with folklorist Alan Lomax, in which he claimed to have invented jazz around 1902, are now read as self-promotion as much as testimony. Scholars also weigh the technical limits of acoustic recording, which captured a narrow frequency range and a small ensemble arrangement, against the lived sound of bands in dance halls and parades. The origin of key styles, such as the blues, stride piano and Kansas City riffing, remains a matter of interpretation rather than settled chronology.
Gender and representation have become a significant part of recent research. Women instrumentalists were long treated as exceptions or as imitators of men. Lil Hardin Armstrong, a pianist, composer, arranger and bandleader who worked in Chicago in the 1920s and was known as "Hot Miss Lil", is now recognized as one of the most prominent women of early jazz, although biographers differ on how much of her husband Louis Armstrong's career she shaped. Mary Lou Williams wrote arrangements for Duke Ellington and Benny Goodman and mentored bebop musicians, and her late lecture-recitals questioned the canon of accepted masterworks and the racial account of jazz's background. Alice Coltrane, a pianist, organist and harpist who led her own groups after John Coltrane's death in 1967, received less critical attention than her husband, partly because of her turn to spiritual and devotional music. Sherrie Tucker has argued that feminized forms, such as vocal performance, flute playing and sweet bands, were often excluded from the category of "jazz" for that reason, and that gender analysis widens what the field studies.
The final debates concern commercialization, cultural ownership and the status of jazz as art. The music began in dance halls, parades and nightclubs, and many of its most successful performers earned their living from entertainment; the big bands, Ellington's concert ambitions and the 1938 Carnegie Hall concert of Goodman's band show how the two roles overlapped. Institutional recognition, including concert series, prizes and national resolutions, has encouraged the view of jazz as a serious art form, but critics such as Wynton Marsalis have treated some commercial offshoots, including fusion and smooth jazz, as departures from the tradition, while recent scholarship has taken fusion more seriously. Questions of ownership are also central: white bandleaders and recording artists reached large audiences in the early decades, Black musicians often received less credit and income, and debates continue over who may claim the music's heritage and who controls its interpretation and marketing.
