Johann Sebastian Bach (March 21, 1685 O.S. – July 28, 1750 N.S.) was a prolific German composer and organist whose sacred and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity. Although he introduced no new forms, he enriched the prevailing German style with a robust contrapuntal technique, a control of harmonic and motivic organisation from the smallest to the largest scales, and the adaptation of rhythms and textures from abroad, particularly Italy and France.
