Johann Sebastian Bach (31 March 1685 – 28 July 1750) was a German composer and musician of the Baroque period. He is known for instrumental compositions such as the Art of Fugue, the Brandenburg Concertos, and 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 the Western art musical canon.
