Johann Sebastian Bach (pronounced ) (March 21; 1685 O.S. July 28; 1750 N.S.) was a 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; an unrivalled control of harmonic and motivic organisation in composition for diverse musical forces; and the adaptation of rhythms and textures from abroad; particularly Italy and France.
