Johann Sebastian Bach dedicated six concertos to Margrave Christian Ludwig of Brandenburg-Schwedt, now commonly called the Brandenburg Concertos, BWV 1046–1051.

Johann Sebastian Bach 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.

A concerto is, from the late Baroque era, mostly understood as an instrumental composition, written for one or more soloists accompanied by an orchestra or other ensemble. The typical three-movement structure, a slow movement preceded and followed by fast movements, became a standard from the early 18th century.

Margrave Christian Ludwig of Brandenburg-Schwedt, a member of the House of Hohenzollern, was a Margrave of Brandenburg-Schwedt and a military officer of the Prussian Army. The margravial title was given to princes of the Prussian Royal House and did not express a territorial status. He is best known as the recipient of Johann Sebastian Bach's Brandenburg concertos.

The Brandenburg Concertos by Johann Sebastian Bach are a collection of six instrumental works presented by Bach to Christian Ludwig, Margrave of Brandenburg-Schwedt, in 1721. The original French title is Six Concerts Avec plusieurs instruments, meaning "Six Concertos for several instruments". Some of the pieces feature several solo instruments in combination. They are widely regarded as some of the greatest orchestral compositions of the Baroque era.
