German composer and musician of the Baroque period. He is known for instrumental compositions such as the Brandenburg Concertosand the Goldberg Variations, and for vocal music such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival he has been generally regarded as one of the greatest composers of all time.Bach enriched established German styles through his mastery of counterpoint, harmonic and motivicorganisation, and his adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include hundreds of cantatas, both sacred and secular. He composed Latin church music, Passions, oratorios, and motets. He often adopted Lutheran hymns, not only in his larger vocal works, but for instance also in his four-part chorales and his sacred songs. He wrote extensively for organ and for other keyboard instruments. He composed concertos, for instance for violin and for harpsichord, and suites, as chamber music as well as for orchestra. Many of his works employ the genres of canon and fugue.
