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 generally regarded as the supreme composer of the Baroque style, and as one of the greatest composers of all time.
