How large was the classical orchestra?
I am often asked how large the orchestras were when you compare Haydn, Beethoven and Mozart. Here I have made a chart that shows the number of parts in the score, based on the sources of the time. And I have extended it with a table that shows the number of musicians.
Classical orchestra: scoring comparison chart
In the score Added since the composer’s previous work Absent
Parts = wind, brass and percussion parts written in the score, not players. Every symphony also has strings; their number was not written down. In Beethoven’s Fifth the piccolo, contrabassoon and trombones play only in the finale; in the Ninth, the triangle, cymbals and bass drum.
Woodwinds piccolo · flute 1–2 · oboe 1–2 · clarinet 1–2 · bassoon 1–2 · contrabassoonBrass horn 1–4 · trumpet 1–2 · trombone 1–3Percussion timpani · triangle · cymbals · bass drum
Number of musicians at the first performances
Strings are given as first + second violins · violas · cellos · double basses. Winds: how many players took each written wind part, one or two.

Notes
- There was no single “Beethoven orchestra”. The Eroica was first played privately, in Prince Lobkowitz’s palace, with the forces of a chamber orchestra; the Eighth was first heard with 69 string players.
- Haydn’s London orchestra of 1795 was larger than the orchestras at Beethoven’s own Vienna concerts of 1800–1808.
- The scoring did not grow in a straight line. The Fourth Symphony has one flute, and the Seventh and Eighth return to two horns, two trumpets and no trombones.
- For Haydn’s orchestra at the Esterházy court in the 1760s and 1770s, the figures in the literature differ, from about a dozen players to 22. None is given here.
