Orchestral music

Beethoven wrote nine symphonies, nine concertos, and a variety of other orchestral music, ranging from overtures and incidental music for theatrical productions to other miscellaneous "occasional" works, written for a particular occasion. Of the concertos, seven are widely known (one violin concerto, five piano concertos, and one triple concerto for violin, piano, and cello); the other two are an unpublished early piano concerto (WoO 4) and an arrangement of the Violin Concerto for piano and orchestra (Opus 61a).
