Johann Sebastian Bach by David Hart

Johann Sebastian Bach (German pronunciation: [joˈhan] or [ˈjoːhan zeˈbastjan ˈbax]) (31 March 1685 [O.S. 21 March] 28 July 1750) (often referred to as Bach) was a German composer and an organist, whose ecclesiastical and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity.[1] 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, and the adaptation of rhythms, forms and textures from abroad, particularly from Italy and France.

Revered for their intellectual depth, technical command and artistic beauty, Bach's works include the Brandenburg concertos, the Goldberg Variations, the Partitas, the Well-Tempered Clavier, the Mass in B Minor, the St. Matthew Passion, the St. John Passion, the Magnificat, The Musical Offering, The Art of Fugue, the English and French Suites, the Sonatas and Partitas for solo violin, the Cello Suites, more than 200 surviving cantatas, and a similar number of organ works, including the celebrated Toccata and Fugue in D minor and Passacaglia and Fugue in C minor.

Bach's abilities as an organist were highly respected throughout Europe during his lifetime, although he was not widely recognised as a great composer until a revival of interest and performances of his music in the first half of the 19th century. He is now regarded as the supreme composer of the Baroque, and as one of the greatest of all time.
