The Brandenburg Concertos (BWV 1046–1051) by Johann Sebastian Bach is a collection of six instrumental works presented by Bach to Christian Ludwig, Margrave of Brandenburg-Schwedt, in 1721 (though probably composed earlier). The original French title is Six Concerts à 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.
