The surviving performing parts for the B minor suite date from about 1738 or 1739, in Bach's Leipzig years, though the music may be older; the solo flute part is written in a way that suggests a specific player he had at hand. Of the four orchestral suites this is the only one in a minor key and the only one with a concertante soloist, so it stands somewhere between suite and concerto. It ends with the Badinerie, a fifty-second movement that has become the most widely recognised piece Bach wrote for flute.
