Johann Michael Bach’s prelude to “Der du bist drei in Einigkeit” is a well written four part piece. The tonal development is a bit strange. The piece start with a G major chord and ends with and A major chord. In between the music seems to hesitate between G major and e minor so the ending on a comes a bit as a surprise.
The recording was done on the sample set of the Mascioni of the parisch church in Azzio, made by Piotr Gabrowsky.
