Johann Sebastian Bach (March 21, 1685-July 28, 1750) was a German Baroque composer. He was one of the greatest composers of all time, but during his lifetime, he was little-known and was mostly recognized for performing on the organ. Bach composed in many established musical forms, including, for example, the cantata and fugue, and developed them into complex and sublime pieces. He composed over 1,100 works in almost every musical genre (except opera).
Bach was born and died in Germany, and spent his entire life there, working as an organist, teacher, and composer. He had over 20 children, including four who became famous musicians in their own right, including Carl Philipp Emanuel, Wilhelm Friedemann, Johann Christoph Friedrich, and Johann Christian.
