Ludwig van Beethoven was a German composer and pianist. A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential of all composers.
Beethoven composed in several musical genres and for a variety of instrument combinations. His works for symphony orchestra include nine symphonies (the Ninth Symphony includes a chorus), and about a dozen pieces of "occasional" music. He wrote seven concerti for one or more soloists and orchestra, as well as four shorter works that include soloists accompanied by orchestra. His only opera is Fidelio; other vocal works with orchestral accompaniment include two masses and a number of shorter works.
His large body of compositions for piano includes 32 piano sonatas and numerous shorter pieces, including arrangements of some of his other works. Works with piano accompaniment include 10 violin sonatas, 5 cello sonatas, and a sonata for French horn, as well as numerous lieder.
