Symphony once meant accord of sound—now a multi-movement orchestra epic
A symphony today is an extended Western classical piece, usually for orchestra in three or four movements with a sonata-form opener. Forces run roughly thirty to one hundred players reading a full score while each musician holds only a part. Vocal soloists appear in landmarks such as Beethoven's Ninth and Mahler's Second.
Greek symphōnía meant agreement of sound; medieval Latin could name drums or hurdy-gurdies, and sixteenth-century English sometimes meant dulcimer. Sacred collections by Gabrieli, Schütz, and others used the title before the word settled. Baroque opera sinfonias—fast, slow, fast—fed the orchestral form; overture, symphony, and sinfonia stayed interchangeable deep into the 1700s. Early ensembles were flexible continuo bands, not fixed nineteenth-century sections.
Eighteenth-century aristocrats, especially around Vienna, sponsored small orchestras that made the genre intense daily culture across estates and town houses. Scoring grew from four-part strings to paired winds, horns, trumpets, and timpani. Haydn wrote at least 106 symphonies over thirty-six years; Mozart at least forty-seven in twenty-four. Milan, Vienna, and Mannheim—Sammartini, Stamitz, and friends—were early hubs. Three-movement shapes faded slowly; Mozart's 1786 Prague Symphony is a late classic example.
Beethoven raised the stakes from Eroica onward: the Fifth's minor-to-major arc, the pastoral Sixth's birdcalls and storm across five movements, the choral Ninth. Schubert's Unfinished and Great Ninth, Mendelssohn, Schumann, and Berlioz's programmatic Fantastique and outdoor military band symphony followed. Wagner in 1851 dismissed later essays as a mere epilogue, and Lisztian tone poems briefly dominated concert taste, yet the 1870s–80s second age of Bruckner, Brahms, Tchaikovsky, Dvořák, and peers reclaimed absolute orchestral ambition for a century of concert halls.
