Brandenburg Concertos

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. History It is uncertain when most of the material for the Brandenburg Concertos was written. It is clear that the first movement of Concerto No. 1 (BWV 1046) was based on an introduction to Bach's 1713 cantata Was mir behagt, and the second and last may have been as well. It also seems likely that Concerto No. 5 was the last to be written; it features a prominent harpsichord part, which is presumed to be for a new instrument ordered for Prince Leopold from the instrument-maker Michael Mietke and paid for by Bach in Berlin in 1719. Speculation regarding the composition dates of the other concertos varies, taking into account the styles of the pieces as well as the instrumentation Bach would have had available during his years prior to the date of the compiled manuscript. In 1721, Bach compiled the six concertos, writing them almost entirely in his own hand instead of leaving the work to a copyist. He presented the collection to Christian Ludwig, Margrave of Brandenburg-Schwedt, under the title Six Concerts à plusieurs instruments (Six Concertos for several instruments) with a dedication dated 24 March. Translated from the original French, the first sentence of Bach's dedication reads:
