The melody of "Wer nur den lieben Gott lässt walten" is of itself already a bit chromatic. Marpurg enhances this aspect in his prelude based on this melody, and creates a composition full of suspensions and dissonants. The choral melody is playd with the pedals, the hands play a three part accompaniment. Because of the powerful, chromatic character of this composition, I play it with a plenum registration to match that character.
