Johann Sebastian Bach ( 21 March 1685 O.S. – 28 July 1750 N.S.) was a German composer and organist whose sacred and secular works for choir, orchestra and solo instruments drew together almost all of the strands of the baroque style and brought it to its ultimate maturity. Although he introduced no new musical forms, he enriched the prevailing German style with a robust and dazzling contrapuntal technique, a seemingly effortless 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.
