The Brandenburg Concerto is the most famous music group in many orchestral works by the German composer J.S. Bach (1685~1750). There are 6 songs in total, numbered BWV1046-1051, each of which has a different instrument combination. This set of music was called "the most amazing miracle in all music" by Wagner.

In 1721, Bach collected his six best concertos dedicated to the Marquis Christian Ludwig of Brandenburg. This is the famous "Brandenburg Concerto" (Brandenburg Concerto) also known as Brandenburg There are six concertos in total, numbered BWV1046-1051. These six concertos are generally considered to be music composed by Bach for the then Grand Duke of Brandenburg Christian Ludwig, but according to German musicologist Heinrich Bessler (Heinrich Bessler) strict It turns out that they were actually written for Leopold, the young prince of Kersten, who was a high-level music lover.

In the winter of 1718 to 1719, Bach travelled from Ketten to Berlin to perform for the Grand Duke of Brandenburg. The Grand Duke asked Bach to send him some works. Bach selected these six concertos from the works he created in Kotten and added them after copying. The dedication was dedicated to the Grand Duke. These six concertos are not a set, and each requires a different combination of instruments, so Bach gave them the title "Concertos of Six Different Instruments". For these concertos, Bach used the possible instruments at the time. Still, the Dagong's music team only had six musicians, and even the sixth with the least orchestration of these concertos required seven instruments, which was impossible to play. His collection has been on hold for thirteen years. After the Grand Duke's death, the assembled musicians were disbanded, and the unused scores were sold for a concerto for the waste paper price of forty-eight cents. Fortunately, these concertos were bought by Bach's disciple and the famous composer Chirenberg at the time and were later given to his disciple, the daughter of the Duke of Mary of Prussia, who was also the sister of Frederick the Great. These manuscripts It was saved.
