This fourth volume of organ music by one of the greatest German composers for the instrument includes free preludes, a form in which Buxtehude excelled, as well as preludes based on familiar Lutheran chorales, part of a repertoire that brought musical distinction to the city of Lübeck in the second half of the seventeenth century. Of particular note are the three Praeludia (of which Buxtehude composed more than 20), the first (Track 1) an impressive work in five parts with two fugues.
