The partitia "Von Gott wil ich nicht lassen" is one of Leyding's two remaining chorale preludes (the other one was posted a week ago on this site: http://www.contrebombarde.com/concerthall/music/32435). It consists of a set of six variations on the chorale melody. The first three are manualiter, the last three feature a pedal part as well. The last variation contains even a double pedal part, where one of the two parts plays the chorale melody. This partita is a rich and imaginative work, that makes one wish more of Leyding's chorale bound work had survived.
