Bach, bahk, Carl Philipp Emanuel (1714-1788), was a German composer. He was the second oldest son of the famous composer Johann Sebastian Bach. Bach wrote in almost all of the forms of his day except opera. His music had a strong influence on the styles developed later by the Austrian composer Joseph Haydn and the German composer Ludwig van Beethoven. Many of his symphonies, concertos, keyboard sonatas, and chamber works are intense and dramatic. Emotion dominates his most successful vocal works, which include a Magnificat (1749) and the oratorio The Israelites in the Wilderness (1769).
