      "text": "A symphony is an extended work for orchestra, usually in three or four movements, that is among the most ambitious forms in Western art music. The term comes from the Greek symphonia, meaning \"agreement\" or \"sounding together,\" and in the eighteenth century it came to denote a multi-movement instrumental piece that alternates contrasting tempos and moods. Although the form grew out of the Italian opera overture and the Baroque concerto, it became the defining genre of the classical period and, after Beethoven, a vehicle for expressing philosophical, national and personal ideas on a grand scale.\n\nThis entry traces how the symphony developed from its Italian and Mannheim origins through the Viennese Classical masters, the Romantic and late-Romantic expansion of scale, twentieth-century experiments, and its global spread. It also explains the musical structures that define the genre, including sonata form, the four-movement plan and the orchestral resources on which it depends. Finally, it considers the acoustic basis of orchestral sound, the institutions that sustained symphonic life, and the political and critical debates that have shaped the repertoire, such as its use in national identity projects and disputes over the canon."

      "heading": "Definition and etymology",
      "text": "The English word \"symphony\" comes from the Greek symphōnía, a compound of syn- (\"together\") and phōnē (\"sound\"). In ancient usage it denoted concord, the agreement of sounds, and Greek theorists applied it to consonance in contrast to dissonance. The term reached Western Europe through Latin symphonia. In the Middle Ages the Latin form was attached to several instruments, especially those able to sound more than one pitch at once, and by the late sixteenth century composers were using it in the titles of vocal and instrumental collections. Giovanni Gabrieli's Sacrae symphoniae of 1597 is a well-known early instance. The word's application to an orchestral genre came much later. English dictionaries record the sense of an elaborate orchestral work in several movements only from 1789, and the meaning crystallised in the decades around the Classical style of Haydn.\n\nBefore that point, \"symphony\" was a loose label. A prelude, a postlude, an interlude or any short instrumental piece could be called a symphony, and for much of the eighteenth century the terms overture, symphony and sinfonia were treated as interchangeable. The Italian word sinfonia is the direct counterpart of the English term and, in English usage, most often denotes a seventeenth- or eighteenth-century orchestral piece placed before or between the acts of an opera, oratorio, cantata or suite. The most immediate forerunner of the genre is the opera sinfonia, which by the eighteenth century had settled into three contrasting movements in a fast–slow–fast pattern. Its gradual detachment from the stage and its growth into an independent concert work are discussed in the antecedents section.\n\nThe symphony is distinguished from related forms by its scoring, its length and its architecture. An overture is usually an introductory piece, written for a stage work or later performed on its own as a concert overture. A concerto is built around one or more soloists set against an orchestra, and its drama depends on the contest between soloist and ensemble; the symphony has no soloist and gives its attention to the orchestra as a whole. A symphonic poem, a nineteenth-century development associated with Franz Liszt, is generally a single continuous movement organised around an extra-musical idea, whereas the symphony normally divides into several movements. These distinctions are not absolute, since some composers blurred the lines, but they serve to separate the genre from its neighbours.\n\nThree features are usually taken as defining the mature symphony. The first is orchestral scoring: the work is written for a full orchestra, with a string section at its core and, in the course of the period, woodwind, brass and percussion added to it. The second is multi-movement form, most often three or four movements that contrast in tempo and character. The third is extended duration: a symphony runs considerably longer than a sonata, a string quartet or most other instrumental pieces of its time. Exceptions exist. Some symphonies, such as Beethoven's Ninth and Mahler's Second, include voices, and some multi-movement orchestral works avoided the name altogether. Calling a work a symphony also carried an implication of weight, so very short or deliberately light pieces were rarely given the title."

      "heading": "Antecedents before the Classical symphony",
      "text": "The Italian opera sinfonia\n\nThe most direct ancestor of the symphony was the instrumental introduction to opera. In late seventeenth-century Naples, composers such as Alessandro Scarlatti standardized an overture in three linked sections arranged fast–slow–fast, a layout often called the Neapolitan overture. The opening allegro was usually bright and rhythmically crisp, the middle section was lyrical or song-like, and the closing movement was brisk, often in a dance rhythm. Its function was practical: it signalled the start of the performance, settled the audience and set the mood before the curtain rose. Because it stood apart from the drama, the sinfonia could also be played as an independent concert item, and the form travelled with the operas that used it to Italy, Vienna and northern Europe.\n\nThe concerto grosso, the sonata da chiesa and the ritornello\n\nBaroque instrumental music supplied the structural models that the symphony later absorbed. In the concerto grosso, exemplified by Arcangelo Corelli's Op. 6, published in 1714 after his death, a small solo group, the concertino, alternated with a larger string body, the ripieno or tutti. Many movements in this genre relied on the ritornello principle, in which a recurring tutti theme returns in the home key between contrasting episodes. Antonio Vivaldi did much to systematize this procedure, and its alternation of block-like orchestral statements with contrasting material anticipates the textures of later orchestral forms. The sonata da chiesa, a four-movement church sonata in slow–fast–slow–fast order, offered a parallel model of contrasting tempos within a single cycle, which shows that multi-movement instrumental works were already familiar well before the symphony was named as a genre.\n\nMilan, Venice and Mannheim\n\nGiovanni Battista Sammartini, active in Milan, wrote dozens of sinfonias that were increasingly independent of opera. His works, typically in three movements in his early output, emphasised clear phrasing, lyrical melody and a homophonic texture that contrasted with the contrapuntal style of earlier generations. His music gained wide circulation and influenced younger composers who came to Milan and absorbed his idiom. In Venice, opera sinfonias were likewise common, and the Venetian stage kept the three-movement overture in circulation.\n\nThe court orchestra of the Elector Palatine at Mannheim in Germany, directed from 1745 by Johann Stamitz, became the most influential ensemble of its era. Its players were noted for disciplined ensemble and for their handling of dynamics: they used graded swells from soft to loud, which became known as the Mannheim crescendo, and sudden contrasts between piano and forte. Other effects, such as the rising arpeggio sometimes called the Mannheim rocket, were used to create spectacular climaxes. The Mannheim composers wrote symphonies that increasingly included a minuet, helping to make a fuller four-movement cycle a regular pattern.\n\nBerlin, Vienna and the four-movement plan\n\nAround the middle of the eighteenth century, two other centres shaped the emerging symphonic cycle. At the court of Frederick the Great in Berlin, composers including Carl Philipp Emanuel Bach, Johann Gottlieb Graun and Franz Benda cultivated an expressive style that stressed sudden changes of mood and fine gradations of feeling. In Vienna, composers such as Georg Christoph Wagenseil and Georg Matthias Monn wrote symphonies in the 1740s and 1750s that gradually adopted a fixed sequence of movements: a fast sonata-style opening, a slow movement, a minuet and a fast finale. This pattern was not established overnight. Earlier works varied in their number of movements, and the minuet and the slow movement were added and reordered over time. By the 1760s, however, the four-movement plan had become the norm that Joseph Haydn would soon develop in his early symphonies."

      "heading": "Classical symphonic form",
      "text": "The four-movement plan\n\nBy the late eighteenth century, the Classical symphony had settled into a layout of four contrasting movements. With rare exceptions, the four movements of a symphony conform to a standardized pattern. The first movement is brisk and lively; the second is slower and more lyrical; the third is an energetic minuet or a boisterous scherzo; and the fourth is a rollicking finale. The opening movement was usually the largest. It is generally the longest and most substantial of the four, and it is typically written in sonata form. Some first movements began with a short, slow introduction, as in Haydn's Symphony No. 92, whose introduction starts in the tonic and moves through the parallel minor before the main theme appears.\n\nThe third movement took its shape from the dance. Joseph Haydn first made the minuet standard equipment in a symphony. Its usual design was ternary: first the minuet or scherzo itself, then a contrasting section often scored for a smaller group of instruments, called a trio, and finally the minuet returns. The finale was faster and lighter in character. Its form varied; Haydn's Symphony No. 100, for example, ends in sonata-rondo form.\n\nSonata form\n\nSonata form was the organizing principle of the Classical opening movement, and it developed during this period as a flexible way of arranging musical material. Its first section, the exposition, presents two contrasting themes. The first is anchored in the home key; the second, following a transition, appears in a related key, usually the dominant in a major-key movement or the relative major in a minor-key one. The development section then fragments and reworks this material and moves through distant keys. In Haydn's Symphony No. 100, a development-like section in the center of the movement contains a surprise timpani strike followed by a traversal of many distant keys. The recapitulation restates both themes in the home key, which resolves the tonal tensions the exposition set up. Haydn often used sharp contrasts between stability and instability in these sections; in Symphony No. 92, he opens the first theme on a dominant seventh chord over the tonic, which was unusual for the time.\n\nThematic contrast and motivic logic\n\nClassical composers gave the symphony its sense of progression through contrast and the recycling of small units. Themes were set against one another in mood, rhythm and key, and transitions carried the music from one area to the next. Motivic economy was equally important. The first movement of Haydn's Symphony No. 44 is built on a four-note motif played in unison which occurs throughout the movement. Symphony No. 92 goes further in its concentration: because the rest of the movement reflects many of the ideas presented in its first theme, the symphony has been termed monothematic. In such works, logic comes from the way a few ideas are varied and redistributed rather than from a large number of distinct themes.\n\nOrchestral forces and balance\n\nThe Classical orchestra was built around the strings. By the end of the 18th century, the instrumental line-up of the orchestra had become standardised, with pairs of flutes, oboes, clarinets and bassoons, two or four horns, two trumpets, timpani and strings, while the continuo favoured by Baroque orchestras was abandoned. The earlier works were smaller. Haydn's Symphony No. 6 \"Le Matin\" (1761) used one flute, two oboes, one bassoon and two horns, and woodwinds still served largely coloristic functions, and brass remained limited. Clarinets arrived later, and toward the end of his career, in the London Symphonies, Haydn introduced clarinets as part of the woodwind section.\n\nBalance depended on the way these groups were used. Violins usually carried the principal melody while the lower strings supplied accompaniment. The woodwinds provided diverse tone colors and were often assigned melodic solo passages, and to add volume and to emphasize louder dynamics, horns and trumpets were used. Timpani, which were the only percussion instrument of the period, reinforced tonal centers and marked climactic points. Natural horns and trumpets could play only certain pitches, a limit that composers accommodated in their writing; valves were added to horns and trumpets, allowing for fully chromatic playing, and Heinrich Stölzel was among the first to do this. Those developments belong to the next generation of orchestras, but the Classical arrangement, with strings at the centre and winds, brass and timpani placed with increasing symmetry, is the basis of the seating plan still in use. These textures set the stage for the expansion of the symphony in the works of Beethoven."

      "text": "Joseph Haydn's symphonies form the basis of the Classical repertoire. Much of his output was written for the Esterházy court, where he was employed from 1761. Early works such as No. 6, Le matin, is an early symphony written in 1761 by Joseph Haydn and the first written after Haydn had joined the Esterházy court. Its scoring also drew on the concerto grosso tradition, with unusual virtuoso writing across the orchestral ensemble, which reflected the skill of the court's players. Because the band was small in these years, with only 10-15 players at the time, Haydn could write for individual instruments in ways that a larger ensemble would not easily allow.\n\nHaydn's largest and most influential groups came later, in two commissions from abroad. The six Paris symphonies were completed in 1786. The twelve London symphonies followed in the early 1790s: Symphonies Nos. 93–98, which were composed during Haydn's first visit to London, and Symphonies Nos. 99–104, composed in Vienna and London for Haydn's second visit. The impresario Johann Peter Salomon arranged these visits, which is why the set is also called the Salomon symphonies. The concerts were commercially successful, and the concerts garnered profits nearly double what he had been guaranteed. Public subscription concerts of this kind gave the symphony a market beyond the aristocratic household, a development that also shaped Mozart's later career.\n\nHaydn's music is marked by wit and formal play. The Symphony No. 94 earned its nickname from a sudden, loud chord in the second movement, which Haydn added for the London premiere. The Farewell Symphony (No. 45, 1772) is a more theatrical joke: in its finale the players leave the stage one by one until only two violinists remain. In the finale of No. 35, Haydn plays games with three hammerstrokes (tonic–dominant–tonic) which begin the exposition and are worked extensively in the development. Haydn also helped fix the four-movement pattern, with a sonata-form first movement, a slow movement, a minuet with trio, and a fast finale. Haydn had composed symphonies for decades and perfected the genres to such an extent that other composers followed suit.\n\nWolfgang Amadeus Mozart's last three symphonies, Nos. 39, 40 and 41, were written in the summer of 1788. 26 June, no. 39 in E flat major K 543; 25 July, no. 40 in G minor K 550; 10 August, no. 41 in C major K 551 ('Jupiter'). Mozart was under financial pressure at the time. He was experiencing severe financial difficulties that year and it was also the first year of a significant downturn in his professional success. The works were probably intended for publication, and they are not known to have been commissioned for a specific performance. Mozart's use of key is more dramatic than Haydn's. No. 39 is the only one of the three with a slow introduction, and No. 40 is set in G minor, a darker tonal world. Mozart's dialogue between contrasting musical ideas also owes something to opera. In No. 41, you can hear the influence of opera in the musical dialogues which run throughout the symphony.\n\nThe finale of the \"Jupiter\" Symphony shows Mozart's control of contrapuntal writing. It is not, as is sometimes mistakenly indicated, an actual \"fugue,\" but a standard \"sonata-allegro\" form with heavy use of fugue-like contrapuntal techniques. In its coda, Mozart layers five themes so that they sound together. The nickname is most often attributed to Johann Peter Salomon, although it is thought to have been given to the symphony by either German impresario Johann Peter Salomon, or English music publisher Johann Baptist Cramer. Haydn's wit and Mozart's dramatic control of key and texture are two distinct answers to the same Classical form, and together they set the expectations that later composers, including Beethoven, would inherit."

      "heading": "Beethoven and the expansion of the genre",
      "text": "Ludwig van Beethoven wrote nine symphonies between about 1800 and 1824, and in doing so he widened nearly every dimension of the form that Haydn and Mozart had stabilized. The First and Second Symphonies still rely on Classical procedures and show clear debts to Haydn-style wit and orchestral clarity. From the Third onward, the works grow in length, emotional weight and harmonic risk, and they are usually grouped into a middle or \"heroic\" phase, followed by a late period that includes the Ninth.\n\nThe heroic middle period\n\nThe Third Symphony in E-flat major, op. 55, was completed in 1804 and is usually called the \"Eroica\". Its first movement is roughly twice the length of a typical Classical symphonic movement, and its development section is far longer and more dramatically charged than anything in the earlier repertoire. Beethoven's dedication to Napoleon, later withdrawn, is often cited as a sign of the work's political ambition, but the musical consequences matter more: the symphony treats the orchestra as a vehicle for large-scale conflict and resolution. The first public performance took place in Vienna in 1805.\n\nThe Fifth Symphony in C minor, op. 67, which received its premiere in Vienna in December 1808, rests on a compressed motivic idea. The opening short-short-short-long rhythm (the \"fate\" motif) recurs in all four movements, and the scherzo passes without a break into a finale in which its material returns in triumphant C major. The work shows how a single figure can supply the thematic material for an entire symphony, creating an unusually tight sense of unity within a conventional four-movement plan.\n\nThe Sixth Symphony in F major, op. 68, was premiered on the same December 1808 concert as the Fifth. It has five movements rather than four and carries descriptive titles for its movements, including scenes by a stream, a peasant gathering and a storm. Beethoven reportedly described it as an expression of feeling rather than a piece of pictorial painting. The \"Pastoral\" thus introduced explicit programme into a symphony without abandoning absolute musical structure, a combination that later Romantic composers pursued more openly.\n\nThe Ninth Symphony and the choral finale\n\nThe Ninth Symphony in D minor, op. 125, was composed between 1822 and 1824 and premiered in Vienna at the Kärntnertor Theater on 7 May 1824. Beethoven had been profoundly deaf for many years, so the performance was directed by Michael Umlauf, while Beethoven took part in setting tempos and followed the score. The work is in four movements, but its finale departs from the instrumental tradition: a full chorus and vocal soloists sing Friedrich Schiller's 1785 poem \"An die Freude\" (\"Ode to Joy\"). Beethoven had considered setting the poem for decades, and the vocal finale is the decisive solution to the question of how a symphony might carry a text and a message of universal brotherhood.\n\nThe Ninth's scale is also unprecedented. Its orchestra was the largest Beethoven ever used, and its performance length makes it one of the longest symphonies of its time. Its dramatic opening, built on bare open fifths, and its scherzo, which is the second movement, were equally innovative in sound and rhythm. The work bridges Classical and Romantic practice: its formal control derives from Classical sonata procedures, while its expressive aims and its use of voices point forward.\n\nRedefining the symphony\n\nBeethoven's symphonies altered what composers and audiences expected from the genre. Development sections became large expressive arenas rather than brief transitional passages, and harmonic movement could be dramatic and surprising while still feeling logically motivated. Works were conceived as statements about struggle, heroism and human ideals, not only as entertainment in the court or concert setting. Composers who came after him, including Romantic symphonists, were measured against this model. The Ninth's chorus also encouraged later experiments with voices in orchestral works, such as the choral and vocal symphonies by Berlioz and Liszt and the large vocal symphonies of Mahler. For later generations, the symphony was therefore no longer only an instrumental form, but a vehicle for ambitious artistic and philosophical claims, rooted in the ideals of the Enlightenment and the French revolutionary era that Beethoven admired."

      "heading": "The Romantic symphony and programme music",
      "text": "Hector Berlioz's Symphonie fantastique, Op. 14, was completed in 1830 and first performed at the Paris Conservatoire on 5 December that year, conducted by François-Antoine Habeneck. It is a five-movement work with the subtitle \"Episode in the Life of an Artist,\" and its narrative is semi-autobiographical, drawing on Berlioz's infatuation with the Irish actress Harriet Smithson. Berlioz handed printed programme notes to the audience, a practice new to Parisian concerts, so listeners could follow the story. The structural innovation lies in the idée fixe: a single melody representing the beloved that returns in every movement. It appears as a lyrical theme in the opening Allegro, reappears within a country scene, becomes a waltz at the ball, is heard in the march to the scaffold, and is finally distorted into a grotesque parody in the Witches' Sabbath. Because the same theme travels through the whole work and changes character with each episode, the movements are bound into a dramatic chain, which was a departure from the separate, self-contained movements of the Classical symphony. Beethoven's \"Pastoral\" Symphony had supplied programmatic titles but no comparable recurring idea.\n\nFranz Liszt approached the problem from the other direction. His symphonic poems are single-movement orchestral works that illustrate a poem, a legend, a painting or a landscape. Liszt used the term Symphonische Dichtung for his thirteen works, the first twelve composed between 1848 and 1858 and the last, From the Cradle to the Grave, appearing in 1882. He aimed to give programmatic music the thematic complexity normally reserved for the first movement of a symphony. Two procedures made this possible: cyclic form, which Beethoven had used to link movements, and thematic transformation, in which a theme is reshaped into something new to suit changing images and emotions. Les Préludes is one of the best-known examples. Liszt's model later influenced composers such as Smetana, Dvořák and Richard Strauss.\n\nRobert Schumann and Johannes Brahms wrote symphonies that remained within the Classical four-movement design while adopting Romantic lyricism and harmony. Schumann's First Symphony, the Spring, dates from 1841, and his later symphonies show a lyrical, song-like idiom and occasional links between movements. Brahms, who completed his four symphonies between 1876 and 1885, engaged most directly with Beethoven. His First Symphony moves from darkness to light in a way that echoes Beethoven's Fifth, and its finale contains a broad theme that recalls the \"Ode to Joy\" of Beethoven's Ninth. Brahms also reworked sonata form. In the first movement of his Fourth Symphony, he omits the exposition repeat, arguing through the music that the continuous unfolding should not be interrupted. Its finale is a chaconne of thirty variations on a bass theme, a Baroque technique that gives the symphony a formal logic built on continuity rather than contrast alone.\n\nPyotr Tchaikovsky's symphonies combine personal emotional expression with cyclic thematic design. His Fourth Symphony (1878) and Fifth Symphony (1888) both use a recurring \"fate\" motto that returns across movements and is transformed. In the Fifth, the motto appears in the slow introduction, returns in the development, and is recast in the major key in the finale. The Sixth Symphony, the Pathétique (1893), departs further from convention. Its second movement is a waltz in 5/4 time, its third is a march that builds to a climax, and it ends with a slow, mournful finale rather than a fast one. Tchaikovsky conducted its premiere in St Petersburg in October 1893 and died a few days after the performance. Across these three symphonies, the emotional arc and the cyclic motto work together to give the Romantic symphony a narrative and psychological coherence that is closer to programme music than to the abstract Classical model."

      "heading": "Bruckner and Mahler",
      "text": "Anton Bruckner\n\nAnton Bruckner built his symphonies on the sonorities of the church organ. He layered brass choirs over sustained, pedal-like bass lines and built his climaxes through long, repeated stages of accumulation, so his movements often run far longer than those of his Viennese predecessors. The early works, including the Study Symphony in F minor and the so-called \"Nullte\" (No. 0), sit outside the numbered cycle of nine.\n\nThe more pressing problem for Bruckner's symphonies is textual. He revised most of them repeatedly, and the revisions often changed the music substantially rather than only the orchestration. The First Symphony exists in an 1866 original, an 1877 \"Linz\" revision and an 1891 \"Vienna\" version. The Eighth survives in versions of 1887, 1890 and a severely cut 1892 text that Bruckner was persuaded to publish. Robert Haas, who edited the symphonies for the Bruckner Gesamtausgabe in the 1930s and 1940s, combined passages from different versions into single scores, and his editions were later criticised for this. His dismissal after the Second World War, due to his Nazi connections, led to the appointment of Leopold Nowak, who produced separate editions of each version and documented the differences in detail. Nowak's post-war editions have since become more commonly performed and recorded, although some conductors continue to prefer Haas's texts. Performers thus face a choice among versions that has no single authoritative answer.\n\nGustav Mahler\n\nMahler's symphonies extend the genre by bringing in voices, expanding the forces and drawing on song. The Eighth Symphony, composed in 1906, is scored for eight vocal soloists, a double chorus and a boys' chorus, and it is organised into two parts. The first sets the medieval hymn Veni, creator spiritus, and the second sets the closing scene of Goethe's Faust. It was first performed in Munich in September 1910 under the composer, and its nickname, \"Symphony of a Thousand\", refers to the scale of its performing forces.\n\nDas Lied von der Erde (1908–09) is not numbered, although it was written between the Eighth and Ninth symphonies. It consists of six songs for tenor and alto or baritone with orchestra, based on Hans Bethge's German versions of Chinese poetry, and it is often described as a \"song-symphony\" that blends two forms. Its pentatonic writing and its polar contrasts of night and day, youth and death, reflect Mahler's engagement with East Asian material. Mahler's reluctance to number the work is often linked to his superstitious fear of the \"Curse of the Ninth\", the fact that Beethoven and Bruckner both died after completing a ninth symphony.\n\nMahler's conception of the symphony\n\nMahler wrote that a symphony should embrace the whole world, and his works put this idea into practice by admitting almost any kind of material. Folk song, marches, Ländler and popular tunes appear beside elaborate counterpoint, and the music often turns them into irony or grotesquerie through abrupt shifts of character. Movements may be grouped in unusual ways or contrasted so sharply that the work seems to hold several worlds at once, and the relation between the movements is therefore as important as the structure of each one.\n\nPressure on size and duration\n\nThe scale of the late-Romantic symphony pushed performance times towards and beyond eighty minutes and placed heavy demands on orchestras, audiences and conductors. Later composers reacted in different ways. Some, such as Schoenberg, moved towards chamber-scale ensembles and compressed forms, while Sibelius pursued concision within a symphonic framework. Others accepted the expanded scale but sought new ways to organise it. These divergent responses shaped the symphony's development after 1900."

      "heading": "Nationalism and national schools",
      "text": "From the mid-nineteenth century the symphony became one of the main vehicles through which composers on the European periphery and in the Americas asserted a distinct national voice. Rather than treating the Austro-German symphony as a neutral standard, these composers typically drew on vernacular song, dance rhythms, regional legend and modal or pentatonic colouring, and set these materials against the sonata-based architecture inherited from Vienna. Their fidelity to folk sources varied widely, but they shared the conviction that a symphony could carry local identity without abandoning large-scale formal logic. The genre's connection to Romantic ideas of the nation, and to nationalism more broadly, is what gave these works their political weight.\n\nDvořák and the \"New World\"\n\nAntonín Dvořák's Symphony No. 9 in E minor, Op. 95, subtitled \"From the New World\", is the best-known case of a national idiom travelling across borders. He wrote it in the United States between 1892 and 1895, while directing the National Conservatory in New York, and its premiere at Carnegie Hall on 16 December 1893 was a major success. Dvořák was attracted to African American spirituals and Native American music, but he treated them as a source of character rather than as material to be quoted. The symphony contains no verbatim folk tunes; its pentatonic shapes, dance rhythms and lyrical contours reflect those idioms instead. The Largo's theme later became the spiritual-like song \"Goin' Home\", with lyrics written in 1922 by Dvořák's pupil William Arms Fisher, which shows how readily the melody was absorbed into the American song repertoire. Bohemian rhythmic habits and Germanic structural habits remain audible throughout, so the work is heard both as an American statement and as a Czech composer's reading of the New World. Whether the symphony is truly \"American\" has been debated ever since its premiere, and the debate itself illustrates the difficulty of defining a national school from an immigrant musical culture.\n\nFinland and Sibelius\n\nIn Finland the symphony became bound up with a struggle for cultural and political autonomy. Jean Sibelius's early works drew on the Kalevala, the epic assembled from Finnish oral poetry: Kullervo (1892) was greeted as a foundation of Finnish music, and Karelia Suite (1893) used rugged, folk-inspired material. During the Russification campaigns of the late nineteenth century, Finlandia (1899) functioned as a veiled protest against censorship and later became an informal national anthem. Sibelius's symphonies, however, work differently from this surface nationalism. Modal inflections and folk-derived motives, including a modal-minor pentachord that has been identified as a central Finnish element, are not presented as self-contained tunes. Instead they are compressed, transformed and regrouped across whole movements. This is the sense in which his method is organic and motivic. The First Symphony (1899) and Second (1902) established his reputation, and the Fifth (1915) was commissioned by the Finnish government for his fiftieth birthday, a date declared a national holiday. The Seventh, which compresses the entire symphonic plan into a single continuous movement, shows how far he moved from folk-based surface toward abstract formal control. Sibelius himself emphasised the symphony as \"pure music\", a position that complicates any reading of his symphonies as political documents.\n\nRussia: Glinka, the Mighty Handful and national schools\n\nRussian musical nationalism is traced back to Mikhail Glinka, whose operas A Life for the Tsar and Ruslan and Lyudmila became benchmarks against which later Russian music was measured. In the late 1850s Mily Balakirev gathered a circle of amateur and self-taught composers in St Petersburg with the aim of continuing Glinka's work. The critic Vladimir Stasov championed a Russian music separate from Western traditions, and in 1867 his newspaper praise of a \"small, but already mighty handful\" of Russian musicians gave the group its name, which its members eventually adopted. Its core figures were Balakirev, César Cui, Modest Mussorgsky, Alexander Borodin and Nikolai Rimsky-Korsakov. They drew on Russian themes, literature and folklore, and Balakirev's collection of folk songs gathered along the Volga became a model for later arrangement and thematic borrowing. Rimsky-Korsakov's symphonic output, including Antar, is the clearest symphonic expression of this programme, and it included oriental colouring alongside Russian folk material. His later study of Western fugue and sonata form was regarded by his fellow nationalists as a betrayal of their aims, which shows how strictly the group defined national identity. Contemporaries also contrasted the self-trained nationalists with more cosmopolitan figures such as Tchaikovsky, whose symphonies are discussed elsewhere in this entry.\n\nScandinavia, Central Europe and Iberia\n\nNationalism in the symphony was not limited to these three cases. In Denmark, Niels Gade's symphonies of the mid-nineteenth century show a Northern colouring within a Mendelssohnian framework. In Sweden, Franz Berwald's Sinfonie singulière (1845) experimented with unconventional form, and in Norway, Johan Svendsen's symphonic writing combined a Romantic orchestral idiom with Scandinavian melodic inflections. In Central Europe, Bedřich Smetana's cycle of symphonic poems Má vlast (1874–79) gave Bohemian landscape and history a symphonic-scale expression that became a national emblem for Czech audiences. Iberian symphonic activity in the nineteenth century was less prominent in the wider canon, and national feeling tended to find outlets in orchestral suites, dances and stage music; Joaquín Turina's Sinfonía sevillana (1920) is a later example that uses Andalusian colour in a symphonic frame. These examples show that the national symphony took many forms, from folk-based suites to symphonic cycles built on regional history, and that the common thread was a use of local idiom within an inherited Romantic language."

      "text": "Several composers responded to the late-Romantic expansion of the genre by looking backward. Prokofiev's Symphony No. 1 in D major, Op. 25, known as the \"Classical\" (1917), imitates the transparent textures and balanced phrasing of Haydn, while its harmonic language and rhythmic wit are unmistakably Prokofiev's own. Stravinsky's later symphonic works, such as the Symphony in C (1940) and the Symphony in Three Movements (1945), similarly adopt the outlines, proportions and clarity of earlier music. This neoclassical revival treated the symphony as a set of forms to be reconsidered rather than as a vehicle for ever-larger statements, and it became one of the major alternatives to the late-Romantic model. Neoclassicism\n\nThe pressure on tonality came from a different direction. Arnold Schoenberg completed his Kammersymphonie, Op. 9, in July 1906, singling it out as a \"true turning point\" in his compositional style. The work is scored for a small group of soloists rather than a full orchestra, and it is cast in a single movement divided into five sections. Originally scored for an intimate ensemble of 15 players, it ventures into a new pared down musical landscape. Its five sections follow the pattern of exposition, scherzo, development, adagio and recapitulation, which preserves a sense of sonata form while the home key of E major is repeatedly undermined. Schoenberg seems to delight in finding ways to subvert the tonal world that operates at the heart of post-Romantic symphonic music. The premiere in Vienna in 1907 provoked a sharp reaction in the press. Schoenberg's exploration of atonality and then his formalization of the twelve-tone method, pursued in Vienna by him together with Alban Berg and Anton Webern, produced a body of symphonic thinking that largely stayed within a small circle of modernist composers and performers, and it set the terms for much of the avant-garde debate about the genre after the Second World War. Serialism\n\nDmitri Shostakovich occupies a distinct place in this period. His fifteen symphonies, written between 1925 and 1971, span a student work to a final symphony completed shortly before his death. The Fifth Symphony, premiered in 1937, was completed quickly in spring 1937 and destined for both official acceptance and long-lasting public success, and it is often read in two ways: as an official affirmation of Soviet values and as a coded criticism of the regime. It has served ever since its dramatic 1937 premiere as a blank but evocative canvas upon which countless commentators have projected sharply divergent political ideologies. The Seventh, subtitled \"Leningrad\", was described by the composer as a requiem for the city, and the Tenth's scherzo is traditionally heard as a portrait of Stalin. Shostakovich's Fifteenth opens with a glockenspiel solo, and its extensive quotation from other works has invited much speculation, although the composer later cautioned listeners against taking his own remarks about the first movement too literally. Its reception was positive in the Soviet Union, but mixed in the West.\n\nOlivier Messiaen's Turangalîla-Symphonie is the only symphony by the French composer Olivier Messiaen (1908–1992). Serge Koussevitzky commissioned it for the Boston Symphony Orchestra, and the composer wrote it between 1946 and 1948 with complete freedom to decide the duration, instrumentation and style. The result is a work of about 80 minutes in ten movements, scored for large orchestra with solo piano and the ondes Martenot, the electronic instrument invented in 1928. Messiaen gave the keyboard percussion a role similar to that of an East Indian gamelan, and the percussion section perform a true rhythmic counterpoint. Its premiere on 2 December 1949 was conducted by Leonard Bernstein, who took over from the ailing Koussevitzky. In this work the symphony's rhythmic, timbral and sonic vocabulary is expanded well beyond the conventions of the orchestral genre as it had stood in the nineteenth century."

      "text": "In the United States, Charles Ives wrote four symphonies between 1898 and the mid-1920s. The first is conventional, while the Fourth pushes much further. The Fourth was composed between 1910 and the mid-1920s, and its second movement was the last to be finished. Its scoring is so layered that performances typically require two conductors. Ives's techniques include using two or more keys at once, new kinds of chords, multiple simultaneous musical strands, quartertones. The Fourth also draws on hymn tunes. Its third movement is a fugue built on the hymn \"From Greenland's Icy Mountains,\" and one episode quotes Bach's \"Dorian\" Fugue. The work was only partly heard in Ives's lifetime. The first and second movements were performed in New York in 1927 by fifty members of the New York Philharmonic, and the full symphony was premiered at Carnegie Hall in 1965 under Leopold Stokowski.\n\nOther American symphonists turned to a more populist sound. Aaron Copland's Third Symphony (1946) ends with a finale that grows out of his earlier Fanfare for the Common Man. Samuel Barber's First Symphony (1936) reflects the lyrical, Romantic-leaning idiom that Barber preferred over the modernist mainstream.\n\nIn Mexico, Carlos Chávez built his symphonies on indigenous material. His Symphony No. 2, Sinfonía india, was composed in 1935–36 and is written in a single movement, yet its sections follow the traditional pattern of a three-movement symphony. Its themes come from the Yaqui, Seri and Huichol peoples. The work was premiered by a Columbia Broadcasting orchestra on 23 January 1936, and the Boston Symphony Orchestra gave its first concert performance under the composer in April 1936. Chávez also founded and directed the Orquesta Sinfónica de México, which allowed him to bring Mexican symphonic music to wide audiences.\n\nIn Brazil, Heitor Villa-Lobos drew on Brazilian folk music, and after 1890 composers placed greater emphasis on the folkloric aspect of their national heritage. His symphonies are programmatic. Symphony No. 4 is subtitled A Vitória (The Victory), and its neighbours are subtitled A Guerra (War) and A Paz (Peace), and it was based on literary arguments by Luís Gastão d'Escragnolle Dória. Villa-Lobos wrote twelve symphonies, each alluding to a historic event or place.\n\nIn Japan, the symphony came with Western musical training in the early twentieth century. The composer Kōsaku Yamada was central to this development, and the orchestra he helped establish in Tokyo later became the NHK Symphony Orchestra. In China, composers trained in Europe and Japan adopted symphonic form and combined it with pentatonic scales and folk tunes. Symphonic music spread through the region's conservatories and orchestras in the same period.\n\nAcross the world, the symphony became a standard part of concert life. Touring orchestras and recordings made the repertoire portable. The recordings of Ives and Chávez, for example, have been reissued and recorded by orchestras far from the places where the works were first performed."

      "text": "The symphony's sound depends on an ensemble whose makeup changed substantially between the early eighteenth century and the early twentieth. The string section remained its nucleus throughout. Violins, violas, cellos and basses formed the body of the ensemble, and wind and brass parts were layered onto that core as courts, theatres and concert halls acquired players and as composers found new uses for them.\n\nFrom a string core to paired winds and brass\n\nIn mid-eighteenth-century symphonies, wind and brass parts were often sparing and sometimes optional, depending on the players a court or city could muster. Natural trumpets and horns became the first regular brass. Because they could sound only the notes of the harmonic series, their use was tied to festive or heroic colour, and they were often played with timpani. Trombones came back into orchestral use in the late eighteenth century, and their profile grew through the nineteenth century as wind and brass bands spread.The trombone resurfaced as a part of the orchestra in the late 18th century, gaining further prominence in the 19th century as wind and brass bands emerged.\n\nHistorians often credit Beethoven with fixing the \"standard complement\" of paired woodwinds together with horns and trumpets that dominated the first half of the nineteenth century.The so-called \"standard complement\" of double winds and brass in the orchestra from the first half of the 19th century is generally attributed to the forces called for by Ludwig van Beethoven. He deliberately widened this palette in several symphonies. In the \"Eroica\", a third horn adds harmonic flexibility and, in the Trio, a choral quality to the brass.Beethoven carefully calculated the expansion of this particular timbral \"palette\" in Symphonies 3, 5, 6, and 9 for an innovative effect. The third horn in the \"Eroica\" Symphony arrives to provide not only some harmonic flexibility, but also the effect of \"choral\" brass in the Trio. The clarinet, which was largely absent from early Viennese symphonies, became a standard member of the woodwind group during the Classical period, so that by the early nineteenth century the wind section was typically built from pairs of flutes, oboes, clarinets and bassoons.\n\nValves and the brass revolution\n\nThe chief technical change in brass came from valves. Before they existed, horn players had to stop the bell with the hand, which greatly compromised the tone while producing only a partial chromatic scale.Until that point, there had been no successful valve design, and horn players had to stop off the bell of the instrument, greatly compromising tone quality to achieve a partial chromatic scale. Sources disagree on the date of the first practical valve: one places Heinrich Stölzel's valved horn in 1814,In 1814, German horn player Heinrich Stölzel introduced a valved horn, kicking off a period of great innovation in brass instrument construction. while another gives 1815, and a German patent is recorded for 1818.In 1818, the first horn rotor was patented by Heirich Stölzel and Friedrich Blümel in Germany, and around 1826, German instrument makers began producing valved trumpets. The valve reached the trumpet around 1820,The valve system was first applied to the trumpet in 1820. and the French maker François Périnet developed the modern piston valve in Paris in 1839.The French brass maker François Périnet, perfected what was to become the modern piston valve in Paris in 1839.\n\nValved instruments spread unevenly. The valved trumpet appears to have become a regular presence in German orchestras earlier than elsewhere in Europe,The valved trumpet seems to have established a regular presence in German orchestras earlier than in other countries in Europe. and the new valved instruments gave rise to the tuba. The first tuba in F with five valves dates from 1835, built in Berlin,By 1835, the first tuba, pitched in F with five valves, was invented by Berlin instrument makers Wilhelm Wieprecht and Johann Gottfried Moritz and the tuba eventually displaced the ophicleide in orchestras.By the end of the 19th century, however, it had been largely superseded, in bands by the euphonium and in orchestras by early forms of the modern tuba, some developed from valved ophicleides. Woodwinds underwent a parallel improvement, notably through Theobald Boehm's keywork for the flute and the instruments of Adolphe Sax.The invention of the piston and rotary valve by Heinrich Stölzel and Friedrich Blühmel, both Silesians, in 1815, was the first in a series of innovations, including the development of modern keywork for the flute by Theobald Boehm and the innovations of Adolphe Sax in the woodwinds.\n\nValves also changed how the orchestra sounded as a whole. Brass players could now produce evenly tuned notes across the chromatic range, which encouraged a more uniform and smoother ensemble sound. That sound reached its most celebrated form in the 1950s, under conductors such as Eugene Ormandy and Herbert von Karajan.This also made possible a more uniform playing of notes or intonation, which would lead to a more and more \"smooth\" orchestral sound that would peak in the 1950s with Eugene Ormandy and the Philadelphia Orchestra and the conducting of Herbert von Karajan with the Berlin Philharmonic.\n\nLate-Romantic enlargement\n\nBy the second half of the nineteenth century, the \"standard\" orchestra had grown well beyond the Classical complement. Composers from the Romantic era onward called for additional horns, extra woodwinds, larger brass sections and a wider range of percussion. Late-Romantic scores also pushed the size of the ensemble toward the large forces associated with Beethoven's Ninth Symphony, whose finale adds piccolo, triangle, cymbals and bass drum to the traditional body, and toward the still larger ensembles of the following decades. Wagner's use of extra horns and specially designed tubas is an example of how composers sought new colours within the orchestra. These developments increased the demands on players and on concert halls, and they set the stage for the large orchestras of the early twentieth century.\n\nThe conductor and the orchestra as an institution\n\nEarly orchestras were often directed from the keyboard or by the leader of the first violins, with little separation between conductor and players. The conductor standing apart from the ensemble with a baton became established in the nineteenth century. In this role the conductor shapes balance between sections, tempo and timbre, and the interpretive choices made on the podium became central to how a symphony sounded. Over time the orchestra itself came to be understood as a self-contained interpretive institution, with a recognisable house sound that could outlast any single performance or conductor. Its growth from a small court ensemble into a permanent body, often based in a particular city or hall, is closely linked to these changes."

      "heading": "Concert life and institutions",
      "text": "Public concert series and the first audiences\n\nThe symphony's audience took shape partly through public concerts that were not tied to a court. The Concert Spirituel in Paris began in 1725 to supply music during the Easter period and religious holidays, when the city's opera and theatres had to close. The series was founded to provide entertainment during the Easter fortnight and on religious holidays when the other spectacles were closed. Its programmes mixed sacred choral music with instrumental works, and listeners who attended its evening performances came chiefly from the prosperous middle class, the lower nobility and visitors from abroad. Because its repertory typically included both symphonies and concertos, the series gave orchestral works a regular public hearing. A 1778 newspaper notice records one of its concerts opening with a symphony by Mozart. The Concert Spirituel became very popular, and concert series modelled after it began to appear in many European cities. Vienna and London both later saw series of the same name.\n\nSubscription concerts and private impresarios\n\nIn eighteenth-century London, the subscription model did the work that the Concert Spirituel had done in Paris. The Hanover Square Rooms, which opened in 1775 with a Bach–Abel subscription concert, hosted series that audiences paid for in advance. Johann Christian Bach and Carl Friedrich Abel had begun their subscription concerts together in 1763 and kept them going in the Rooms until 1783, when Gallini's father-in-law withdrew his financial support. The loss of a patron ended the series, which shows how dependent these ventures were on individual backers.\n\nThe most consequential London series was run by the violinist Johann Peter Salomon. Having been excluded from the established Professional Concerts, he set up his own concerts in 1791, continuing until 1795. He engaged Haydn under a contract that paid for a set of six new symphonies over two seasons. The first two of these London symphonies were given at Salomon's Friday evening concerts in the Hanover Square Rooms, which seated around 500, and Haydn directed from the keyboard. When war with France made it difficult to engage singers from abroad, Salomon suspended his concerts at the end of the 1794 season. He then merged with a rival enterprise under Viotti for the following season.\n\nPermanent orchestras and civic institutions\n\nPermanent orchestras arose in German cities from the mid-eighteenth century onwards. The Leipzig ensemble traces its origins to 1743, when the society known as the Grosses Concert was formed by a group of merchants and nobles, and it became the oldest civic symphony orchestra in the world. Its early players were funded through the society's membership fees, and the original orchestra was made up of sixteen musicians, half of them professionals and half students at the city's university. The concerts first took place in private homes, then moved to the \"Three Swans\" tavern in 1744, where they remained until 1781. Complaints about conditions and audience behaviour in the tavern led the city council to offer a floor of the Gewandhaus, the merchants' trading house, for the orchestra's use, and the first concert there took place in 1781. Felix Mendelssohn, who took on the post of Kapellmeister of the Gewandhaus in 1835 and was the first conductor in the modern sense, later strengthened the orchestra's reputation.\n\nOther orchestras followed the same pattern of civic or private initiative. In Vienna, the Vienna Philharmonic was established in 1842 from a series of concerts linked to a musicians' society. In Berlin, the Berlin Philharmonic emerged in 1882 when its players separated from an earlier concert enterprise and organised themselves as a self-governing ensemble. The Concertgebouw Orchestra in Amsterdam, founded in 1888, was supported by a private concert society and by subscribers.\n\nConservatories and training\n\nProfessional symphonic training developed alongside these orchestras. The Paris Conservatoire, established in 1795 during the Revolution, trained performers and composers who later filled orchestral desks across Europe and shaped the teaching of orchestral playing. In Leipzig, Mendelssohn founded a conservatory in 1843, which became a model for music education in Germany. Such institutions gave the orchestra a steady supply of players and conductors who had studied orchestral technique in a systematic way.\n\nEconomics of the orchestra\n\nOrchestras depended on several revenue sources that were rarely secure on their own. Ticket sales and subscriptions brought in income, but the cost of hiring a large ensemble usually exceeded what these generated. Patrons, municipal authorities and endowments filled the gap. The Leipzig case illustrates the pattern: the merchant society paid for its musicians through membership fees, and the city later provided the hall. The London ventures show the opposite risk, in which the withdrawal of one backer ended a series. These financial pressures remained a central factor in the history of symphony orchestras throughout the nineteenth and twentieth centuries."

      "heading": "Acoustics, harmonics and tuning",
      "text": "The harmonic series and timbre\n\nA sustained note from a pitched instrument is a composite sound. In most strings and winds, the fundamental fixes the note name, while the overtones above it set the tone colour. The fundamental supplies the pitch or note name and the overtones establish the timbre. A tone of this kind can be treated as a sum of simple periodic waves (i.e., sine waves) or partials, each with its own frequency of vibration, amplitude, and phase, which is why Fourier analysis and harmonic analysis are the standard tools for studying instrumental sound. Partials of string and wind instruments lie close to whole-number multiples of the fundamental, forming a harmonic series. Tuned percussion and cymbals, by contrast, produce spectra that are rich in inharmonic partials and may give no impression of implying any particular pitch.\n\nThe relative strengths of these overtones, rather than the pitch alone, let a listener tell instruments apart. The first two harmonics on the flute are very strong, but the remaining harmonics are quite weak. This is what gives the flute its characteristic pure timbre. A violin playing the same note has a weaker second harmonic, but its third through eighth harmonics are much stronger, which makes its timbre richer. Some instruments only produce odd harmonics, such as the pan flute. Within an orchestra, instruments with similar spectra tend to blend, while those with strong upper partials stand out.\n\nThe harmonic series also explains the consonance of the intervals it contains. The first three intervals created by successive pitches in the harmonic series are an octave, a perfect fifth, and a perfect fourth. Because of this relationship, these intervals sound particularly consonant. Later harmonics produce progressively narrower and more dissonant intervals, gradually smaller (thirds, then seconds) and more and more dissonant. This acoustic hierarchy underlies the tuning debates discussed below.\n\nConcert pitch\n\nBefore the twentieth century, no single reference pitch governed European orchestras. In the early seventeenth century, Michael Praetorius proposed a particular A-425 organ pipe as a standard. He argued that higher pitches caused string breakage, pointing out that higher pitches led to broken violin strings. Problems of agreement grew as ensembles enlarged during the Baroque era. The tuning pitch varied from A′ = 415 Hz to A′ = 456 Hz across the period. In Germany, separate standards also coexisted: instruments used for different purposes were often tuned to different pitch standards, called Chorton (\"choir pitch\") and Kammerton (\"chamber [music] pitch\"). Bach's cantatas reflect this, since the organ part is notated a full step lower than the other instruments.\n\nPitch rose during the nineteenth century. The Vienna opera is recorded as using A=447Hz in the 1870s. France attempted to impose order with the Diapason Normal, which set A at 435 Hz; sources differ on the date, with one giving 1859 and another 1858. Proposals for a universal standard had been made earlier. Scheibler presented his Tonometer and his recommendation for A=440 Hz as a universal concert pitch to the Society of German Natural Scientists and Physicians at their meeting in Stuttgart in 1834. That proposal was not widely adopted. A decisive step came in 1939, when delegates from France, Germany, The Netherlands, Italy, and England convened at Broadcasting House in London and agreed on A440. The standard was later adopted by the International Organization for Standardization, in 1955 as Recommendation R 16, before being formalised in 1975 as ISO 16. Even so, practice remains varied: in continental Europe the frequency of A4 commonly varies between 440 Hz and 444 Hz. Period-instrument ensembles, meanwhile, generally work with a lower pitch of about 415 Hz.\n\nEqual temperament and well temperament\n\nEqual temperament is the system in which the octave is divided into 12 perfectly-equal half steps, or semitones. It distributes the tuning error of the circle of fifths evenly across all keys, so that each interval is equally in, and slightly out of, tune. Earlier well-temperaments were different. Some semitones are smaller and some are larger. Overall, perfect fifths tend to be pretty close, while the quality of major thirds varies around the circle of fifths, which gave each key a distinct character.\n\nThe relationship between equal temperament and Bach is often misunderstood. If you are or were ever a college music student, you probably read, or were told, that Johann Sebastian Bach wrote his collection of preludes and fugues The Well-Tempered Clavier in all 24 major and minor keys in order to demonstrate equal tempered tuning. If so, you were misinformed. Bach's aim, according to these sources, was to demonstrate the feasability of composing in well temperament and to demostrate the varying key colors in well tempered tuning as one progresses around the circle of fifths. Bach's organ tuning is thought to have been as close to equal temperament as modern instruments are, although it is known that he was opposed to a strictly mathematical equality of intervals.\n\nEqual temperament was known in theory well before it was adopted. It was known about in Europe as early as the early 17th century, and in China much earlier. But it wasn't used, because the consensus was that it sounded awful: out of tune and characterless. Keyboard tuning then drifted towards it during the nineteenth century, over the protest of many of the more sensitive musicians. Sources differ on when it became normal practice: one states that equal temperament actually did not come into use until the 20th century. For the Classical symphony, this matters because the harmonic colour of a key, and the tension of its thirds, depended on the tuning system of the instruments in use, not on a uniform scale.\n\nHall acoustics\n\nThe perceived balance and clarity of a symphony depend on the room as much as on the score. Reverberation sustains the overlapping tones of an orchestra and enriches its blend, but excessive reverberation smears rapid passages and blurs the inner voices. Early reflections from walls and ceilings reinforce the direct sound and affect how strongly listeners perceive individual sections. Concert-hall designers therefore balance reverberation against definition, and the shape of the stage and the placement of players influence how the orchestral timbres described above reach the audience."

      "heading": "Performance, recording and interpretation",
      "text": "Rehearsal and interpretive choices\n\nA symphony exists in sound only through the decisions of conductors and players. Rehearsal settles balance, articulation and tempo for a particular hall and ensemble, so each performance embodies interpretive choices that the printed score leaves open. Because notation in earlier eras often left many details unstated, the question of how a work should sound became a recurring concern, and its answers have changed from one generation to the next.\n\nHistorically informed performance\n\nThe most sustained effort to recover older practice is the historically informed performance movement. It aims to be faithful to the approach, manner and style of the musical era in which a work was originally conceived. Practitioners work with instruments from the composer's time, either historic instruments or authentic reproductions. Ensembles that took up this approach had to rebuild their technique from the beginning, since players had to relearn the techniques to play those old woodwinds, valveless brass instruments and gut fiddles with their curved bows.\n\nThe movement's chronology is also significant. Its first advocates concentrated their initial work on the Baroque and then Classical repertories, the music in which their findings were most audibly different compared with then-standard practices. The approach reached Beethoven only in the 1980s and Berlioz, Schumann and Brahms in the 1990s. Its most publicised application to the symphony came when Norrington famously applied Beethoven's own metronome markings to his symphonies, with sometimes bizarre results.\n\nThe movement also changed the market. As critics and audiences warmed to this new-old approach, 'normal' symphony orchestras found themselves virtually frozen out of a huge chunk of their repertoire. Crucial recording contracts for massive projects – complete Bach cantatas, or all the Haydn symphonies – went to the rising period-instrument bands. Within the profession, the movement was deeply divisive. From the 1990s a new generation realised that ensembles didn't have to be either/or when it came to instruments and techniques. The way forward was flexibility.\n\nRecording and standardisation\n\nRecording from the early twentieth century onward made interpretations repeatable and comparable. A study of orchestral performances identifies significant tempo modifications across performances spanning from 1898 to 2019, revealing notable trends in performance characteristics, particularly during the transition from pre-war to modern recordings. Comparative analyses of timbre and style also show that the technology itself shaped what listeners hear: the NBC-Toscanini recordings and NY-Bernstein recordings are similar to each other and different from most of the other orchestras, likely due to specifics of the recording technology at the time these recordings were made. There is evidence for newer recordings being more similar to each other, which points toward a convergence of style across major orchestras.\n\nThe influence of period practice has spread well beyond specialist groups. In early-music violin playing, its impact has become so widespread that players from different schools now share a common stock of choices, including articulation devices, dynamic nuances, means of vibrato, tempo and rhythm manifestations, ornamentation, phrasing or fingerings.\n\nRadio broadcasting and commissioning\n\nBroadcasting created a second institutional route for symphonic music, one that favoured new works. The BBC Symphony Orchestra was formed in 1930 under Sir Adrian Boult, only three years after the incorporation of the BBC. Its primary purpose was to serve as a permanent, full-time orchestra performing music for broadcast. The orchestra developed a reputation for performing new music and has provided premier performances of hundreds of musical pieces, many of which were specifically written for broadcast on the BBC. Boult also set a lasting precedent: he began the tradition of inviting contemporary composers to conduct and perform their own works in concerts.\n\nIn the United States, the NBC Symphony Orchestra was conceived by David Sarnoff, the president of the Radio Corporation of America, especially for the conductor Arturo Toscanini. Its first broadcast was on November 13, 1937, and it continued until it was disbanded following Toscanini's retirement after his final broadcast concert on April 4, 1954. Elsewhere, broadcasting institutions supported composers directly. In Prague, the radio orchestra gave world premieres of numerous significant works, including Miloslav Kabeláč's First and Fourth Symphonies, and the tradition of commissioning new works continues today. Radio ensembles of this kind now exist across Europe and in Japan, including the Tokyo-based NHK Symphony Orchestra, and their funding structures vary: the primary funding comes from television licence fees from the Finnish population."

      "text": "Symphonic writing reached the cinema early, first through live accompaniment. In the silent era, pianists and sometimes full orchestras played alongside screenings, often working from compiled repertoires of established concert music. The first American orchestral score is generally identified as the compilation for D. W. Griffith's film The Birth of a Nation (1915), assembled by Joseph Carl Breil from works by Wagner and Grieg. An original composed score is usually traced to Camille Saint-Saëns's music for L'Assassinat du duc de Guise (1908), whose continuous dramatic structure was built around the plot rather than assembled from existing pieces. Max Steiner's score for King Kong (1933) is often cited as the first comprehensive symphonic score for a sound film. Steiner, Erich Wolfgang Korngold, Bernard Herrmann, Miklós Rózsa and Alfred Newman then established the Hollywood idiom, which combined expansive orchestration with recurring themes attached to characters and ideas, a device inherited from late Romantic opera.\n\nFrom the 1960s, film composers increasingly mixed orchestral forces with jazz, pop and electronic elements, and reduced or unconventional ensembles became common. Synthesizers reshaped scoring in the 1970s and 1980s, yet John Williams's scores for Star Wars and Jaws kept the large orchestra central to blockbuster sound, and the Star Wars soundtrack remains among the best-selling non-pop recordings. Symphonic film music therefore functions today both as a working craft and as a repertoire that audiences hear independently of the images, a shift that helped prepare the ground for concert programmes built from screen and game music.\n\nVideo game music has followed a similar path into the concert hall. The Symphonic Game Music Concerts began in 2003 at the Gewandhaus in Leipzig and are regarded as the longest-running series of their kind outside Japan. From 2008 onward, Thomas Böcker's Merregnon productions replaced straightforward orchestral versions of individual tracks with longer, more elaborate arrangements. Symphonic Fantasies (2009), performed by the WDR Radio Orchestra in Cologne, used arranger Jonne Valtonen's technique of overlaying themes from several pieces rather than producing a conventional medley. Some programmes adopt the architecture of the genre itself: Final Symphony is divided into a symphonic poem, a piano concerto and a symphony, each drawn from a different game. Other ensembles pair orchestras with rock bands and choirs, as the Boston-based Video Game Orchestra does, while tours such as the Assassin's Creed concerts field an 80-piece orchestra and choir alongside game footage.\n\nContemporary composers continue to write symphonies in a wide range of idioms, from tonal to post-tonal and electronically augmented styles. New symphonic works are generally brought into being through commissions from orchestras, festivals and other institutions, and this funding structure remains central to whether a living composer's symphony is premiered and repeated. Broadcasting orchestras have historically played a similar role, and the practice of commissioning continues to determine which new scores enter the repertoire.\n\nDigital tools have introduced a more contested dimension. In 2021, an AI system was used to complete Beethoven's unfinished Tenth Symphony, which was then premiered by a live orchestra. The project worked in stages: one model generated the composition as two lines of music, and a second model orchestrated it, both trained on Beethoven's sketches and on the practices of other composers. Responses among musicians and composers were sharply divided, with some welcoming the tool as an aid to ideation and others rejecting the idea of completing a Beethoven symphony by machine. Critics have argued that AI systems, trained on copyrighted material without the consent of rights holders, raise serious intellectual property and economic questions, and that their output recombines existing music rather than creating something new. Some film and commercial composers have described anxiety about being replaced by generated tracks. A 2025 study comparing audiovisual contexts found that AI-generated soundtracks produced greater pupil dilation than human-composed music, yet emotional valence remained consistent across conditions, which suggests that the perceived effect of music on viewers does not map neatly onto its origin."

      "text": "A symphony requires a large ensemble, public performance and usually institutional support, which made it attractive to states that wanted to display collective unity or reward approved art. The clearest twentieth-century cases come from the Soviet Union and Nazi Germany, where the genre's public character made it both a propaganda asset and a target for suppression.\n\nPropaganda and ideological control\n\nThe symphony could serve as direct political statement. In the Soviet Union, Shostakovich's \"Leningrad\" Symphony (No. 7) proved an electrifying propaganda tool for Stalin's wartime government, yet the composer's Eighth and Ninth symphonies did not deliver the triumphalism officials expected. Nazi authorities treated music as a domain of total administration. In 1933 the Reichsmusikkammer was set up with the aim of regulating German musical life. Its figurehead, Richard Strauss, was installed as president of the Reichsmusikkammer in November 1933, and was dismissed from the post in June 1935 after a letter to his Jewish librettist Stefan Zweig was intercepted.\n\nSuppression and banning\n\nNazi policy targeted composers by ancestry and by style. Jewish composers such as Felix Mendelssohn and Gustav Mahler were disparaged and condemned by the Nazis. Mahler's music was banned from performance in much of Europe during the Nazi era. In 1938 an exhibition in Düsseldorf included composers on the basis of their \"racial origins\" (i.e. Jews), or because of the \"modernist style\" of their music. Enforcement extended beyond concert halls: performance, publication, broadcast, or sale of music by composers deemed \"degenerate\" was forbidden by law throughout the Third Reich. Institutions were purged as well; the Vienna Philharmonic later acknowledged that all 13 of its Jewish players had been fired by 1938, and several of them died in the camps.\n\nIn the Soviet Union, the state's control of symphonic music was exercised through the anti-formalism campaign. In February 1948 the Committee for Artistic Affairs issued a decree targeting Shostakovich's music, and Andrei Zhdanov declared the music of Shostakovich, Prokofiev, Khachaturian, and several others destructive to the state. The charge of \"formalism\" was deliberately elastic: it served as a catch-all to castigate any artist who earned the state's displeasure. Performances were curtailed, and Shostakovich's Fourth Symphony, composed in 1935–36, was not performed until 1961, eight years after the dictator's death. The political pressure produced a divided output: he wrote works that paid homage to the state, as well as music \"for the drawer\" that was personal. The condemned composers were formally rehabilitated by a further decree issued on 28 May 1958.\n\nThe symphony as civic emblem\n\nOrchestras and concert halls have long functioned as markers of civic status, and governments often justify their support in these terms. In Tasmania, the minister for the arts described the orchestra's funding as support for its continued success and growth, ensuring that it remains a 'vibrant and integral part' of Tasmania's cultural landscape. The orchestra's standing also rests on economic and cultural reach: it is the most recorded, broadcast and streamed orchestra in Australia and provides employment for over 250 Tasmanians. The Detroit Symphony Orchestra illustrates the other side of this relationship. After facing a significant financial crisis in 2010 which nearly led to bankruptcy, it received a $10 million state award in 2011.\n\nDebates over funding and state support\n\nPublic funding for symphony orchestras remains contested, and the figures used in these debates vary by country and source. Michigan's 2025 state budget included a total of $2.34 million from taxpayers for four symphony orchestras, a sum that was part of $1 billion in pork spending state officials approved for the 2025 budget, according to the report. In 2025 the state also made a one-time allocation through a recovery program: the Michigan Department of Labor and Economic Opportunity awarded $5.65 million in need-based grants through the new, one-time Symphony Economic Recovery Program, supporting all 41 eligible symphony orchestra applicants across the state. In Australia, the Tasmanian orchestra's relationship with its government became entangled with a planning dispute, as it called for a \"common sense rethink\" of the stadium's proposed location, arguing that the site would obstruct sight lines from the Hobart cenotaph and impact the \"orchestra's viability\".\n\nComparative claims also feature in the debate. One commentary asserts that American orchestras receive, on average, thirteen per cent of their revenue from public funding. European orchestras receive fifty per cent or more. That figure comes from an advocacy-oriented source and should be checked against primary financial data. The same commentary reports that the Berlin Senate announced cultural cuts of 10 per cent across 2025, 2026, and 2027, illustrating how budget decisions can affect even heavily subsidised ensembles."

      "heading": "Canon formation and critical debates",
      "text": "The symphony's place at the centre of orchestral life was not settled in the eighteenth century. It was built mostly in the nineteenth and twentieth centuries, when concert programming, publishing and conservatory teaching gradually narrowed the repertory to a small group of works, most of them by composers from the German-speaking lands and Vienna. The canon thus reflects choices as much as quality, and the choices have been contested almost from the start.\n\nThe idea that the genre had reached a terminal point is older than most twentieth-century critics. Writing in 1849, Richard Wagner famously announced the symphony's death at Beethoven's hands and its transformation into music drama. Wagner's verdict was aimed at the imitators who kept writing symphonies after the Ninth, which he regarded as empty repetition of forms. A century later, Beethoven's heirs faced a different threat. Theodor Adorno worried that the conditions for hearing a symphony as a public, temporal argument were eroding, and he held that broadcasting turned the genre into background material for the home. Critics in the later twentieth century kept returning to the theme. Robert Zaller, surveying the output of Classical and later composers, lamented the decline of the form and warned that its fate might signal a wider problem for Western music. Against such pessimism, other commentators argued that the genre was not in danger and that composers in the United States had sustained it through the twentieth century.\n\nThe canon's narrowness is still measurable. A survey of the 2018–19 seasons of fifteen orchestras worldwide found that only 2.3% of performed works were by women, and 95% of the concerts consist of music composed only by men. A later analysis of scheduled works in the 2023/24 reports recorded 7.5% of works were composed by women (down from 7.7% in the 2021/22 report on the same topic), and it found that the top 10 composers — W.A. Mozart, Beethoven, Tchaikovsky, Brahms, Dvořák, Ravel, Strauss, Rachmaninov, Mahler, and Sibelius — accounted for 30.6% of all works. The same report linked this pattern to a growing trend towards the consolidation of a classical 'canon,' predominantly composed of historical white men. The imbalance has several historical sources: women were largely excluded from conservatory training, from commissions and from the institutions that preserved scores, so many symphonies were printed in small runs or never published at all.\n\nEfforts at recovery have therefore focused on archives and performance. Research in Finland, for example, targeted the works deemed to be of greatest interest were those written in the late 19th and early 20th centuries that had remained unpublished or had been forgotten after their premieres, and the project framed its programme as a question of institutional responsibility. The case of Florence Price shows how much depends on chance. Her First Symphony was performed by the Chicago Symphony Orchestra in 1933, but after her death in 1953 her manuscripts passed to a relative with no connection to the music world. In 2009 a cache of papers and scores was found in a dilapidated house in St. Anne, Illinois, and it included a Fourth Symphony that had never been heard in her lifetime. Its belated premiere took place in 2018, and the publisher G. Schirmer subsequently acquired the rights to her catalogue. Scholars have cautioned that the language of \"rediscovery\" can obscure the fact that her music was kept alive within Black musical communities.\n\nMusicology, critical editions and archives remain the main tools for revising the historical picture. Complete editions of composers such as Mozart and Bruckner have corrected inherited texts, identified authentic versions and clarified which of several revisions represents a composer's final intention. Reconstructions of unfinished or lost works, and editions based on newly found sources, can change which symphonies are judged central. Questions of copyright and public-domain status also shape which scores are reprinted and performed, and therefore which names remain visible in the repertory."
