Beethoven, BAY toh vuhn, Ludwig van (1770-1827), was one of the greatest composers in history. His most famous works include the third (Eroica), fifth, sixth (Pastorale), and ninth symphonies; an opera, Fidelio; and his religious composition Missa solemnis.

Beethoven has had a great influence on music. He won for composers a new freedom to express themselves. Before his time, composers wrote works for religious services, to teach, and to entertain people at social functions. But people listened to Beethoven's music for its own sake. As a result, he made music more independent of social, religious, or teaching purposes.
