Treur Gott ich muss dir klagen (alio modo)

This is the twin prelude to the one I uploaded two days ago (http://www.contrebombarde.com/concerthall/music/27682). This time the choral melody is more easily discernible, as it is played in the soprano voice. The other three voices accompany the melody with a motive that is derived from the first phrase of the chorale melody.
I made two versions of the score: a one-pager for saving paper when printing, and a two-pager for use with tablet or monitor (or for printing when you like the more spacious layout).
