Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific authorship of music across a variety of instruments and forms, including orchestral music such as the 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 Schubler 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 generally regarded as one of the greatest composers in the history of Western music.
The Bach family already counted several composers when Johann Sebastian was born as the last child of a city musician, Johann Ambrosius, in Eisenach. After being orphaned at the age of 10, he lived for five years with his eldest brother Johann Christoph, after which he continued his musical education in Lüneburg.
