巴哈 Prelude and Fugue in B-flat major, BWV 560

This Prelude and Fugue in Bb is commonly attributed to Johann Sebastian Bach, and listed as BWV 559, the last of the collection of 8 small Preludes and Fugues, BWV 553-560. In the past it was catalogued as BC.J28-J35. Though most of the set is actually by Bach, this piece, together with BWV 558 and 555 are suspected to having been written by Johann Ludwig Krebs.
