The symphony has 4 movements, and is scored for strings, 2 oboes, 2 bassoons, and 2 horns, the smallest orchestral force employed in his last ten symphonies:

  1. Allegro assai, 3
    , in sonata form. The development section of this movement is based on a theme that does not appear in the development : the four-note figure that will become the principal theme of the Jupiter Symphony.
  2. Andante moderato in E major, 2
    , in modified sonata form, order of first and second subjects reversed in the recapitulation
  3. Menuetto, 3
    , in ternary form
  4. Finale: Allegro assai, 2
    , in sonata form

The autograph score is today preserved in the Biblioteka Jagiellońska, in Kraków.[1]
