Auf, auf mein Herz mit Freuden

Marpurg wrote several choral preludes that are actually two seperate preludes rolled into one. Marpurg's prelude to "Auf! Auf! meine, mit Freuden" is another example of the 'two for the price of one' type of writing.

The first is written in three parts, with the choral melody in the middle voice. The left hand plays an accompaniment in eigth notes.

The second half of the composition show the more interesting adaptation of the choral melody. It is again written in three parts, with the choral melody in the upper voice. The middle voice plays the choral melody in a sort of half canon. The first notes of each phrase of the choral melody are played in canon, after which the middle voice resorts to filling in the blancs of the harmony. The left hand takes care of the forward motion by playing an accompaniment in eigth notes. It's quite a nice piece, that is exemplary of Marpurg's style in writing choral preludes. The result are not exactly masterpieces, but very nice pieces to play and to listen to.
