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.
The recording was done with the Hauptwerk software and the sampleset, made by Sonus Paradisi, of the Schnittger organ in the St. Martini-kerk, Groningen (https://www.sonusparadisi.cz/en/organs/netherlands/groningen-st-martini.html).
