Johann Sebastian Bach (31 March [
O.S. 21 March] 1685 – 28 July 1750) was a German composer and musician of the late
Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral
Brandenburg Concertos; solo instrumental works such as the
cello suites and
sonatas and partitas for solo violin; keyboard works such as the
Goldberg Variations and
The Well-Tempered Clavier; organ works such as the
Schübler Chorales and the
Toccata and Fugue in D minor; and choral works such as the
St Matthew Passion and the
Mass in B minor. Since the 19th-century
Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.
The
Bach family had already produced several composers when Johann Sebastian was born as the last child of a city musician,
Johann Ambrosius, in
Eisenach. After being orphaned at age 10, he lived for five years with his eldest brother,
Johann Christoph, then continued his musical education in
Lüneburg. In 1703 he returned to
Thuringia, working as a musician for
Protestant churches in
Arnstadt and
Mühlhausen. Around that time he also visited for longer periods the courts in
Weimar, where he expanded his
organ repertory, and the
reformed court at
Köthen, where he was mostly engaged with
chamber music. By 1723 he was hired as
Thomaskantor (
cantor with related duties at
St Thomas School) in
Leipzig. There he composed music for the principal
Lutheran churches of the city and
Leipzig University's student ensemble,
Collegium Musicum. In 1726 he began
publishing his organ and other keyboard music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer. This situation was somewhat remedied when his sovereign,
Augustus III of Poland, granted him the title of court composer of the Elector of Saxony in 1736. In the last decades of his life, Bach reworked and extended many of his earlier compositions. He died due to complications following eye surgery in 1750 at the age of 65. Four of his twenty children,
Wilhelm Friedemann,
Carl Philipp Emanuel,
Johann Christoph Friedrich, and
Johann Christian, became composers. (
