Sorge's prelude to "Helft mir Gottes Güte preisen" is again proof of the notion that Sorge was inspired by the tonality of g minor. The piece has a relatively lengthy 3 part introduction before the choral melody enters. For the largest part of the rest of the piece the accompaniment reverts to two parts.
The recording was done with the Hauptwerk software and the sampleset the Transept organ in the Laurenskerk, Rotterdam, made by Sonus Paradisi.
