Johann Philipp Kirnberger, Wer nur den lieben Gott lässt walten
This chorale prelude is a relatively simple bicinium. The left hand provides a lively accompaniment to the chorale melody in the right hand. What makes this piece more interesting, is not the music itself, but the curious fact that Johann Christoph Kühnau added a part for the right hand between the stanza’s of the chorale melody and published it as his own work.
The source for this chorale prelude is manuscript Am. B 396, owned by the Staatsbibliothek Berlin.
Kühnau’s version can be found here.
The recording was done on the sample set of the Silbermann organ of the Stadtkirche Zöblitz by Prospectum.
