Kauffmann’s prelude to “Christus der uns selig macht” is a is a simple yet effective bicinium. The soprano voice plays the chorale melody, the other voice plays an accompaniment based on motives from the chorale melody. The left hand part is notated in the source in using the alto clef. Since not everyone is able to read that, I provide a version with ‘standard’ clefs as well.
The recording was done on the sample set of the Müller-organ in the Sint Bavokerk in Haarlem by Voxus Organs for Hauptwerk.
