The prelude on “Nun lasst uns Gott den Herren” is a nice example of how to transform a simple setting of a chorale into a prelude. Bass and melody follow the harmonisation, and a middle voice is added in eigth notes to fill in the rest of the harmonies and to add motion to the music.
Intruiging is that this piece occurs twice in manucript Am. B 396. Almost as if the copyist had forgotten he had already entered the piece.
