Da Jesu an dem Kreuze stund

This is, I think, one of the most beautiful choral prelude to "Da Jesu an dem Kreuze stund". The manuscript I took it from does not indicate a composer. However, judging from the other pieces in the manuscript and the overall style of the piece it could be written by either Johann Michael Bach or by Johann Pachelbel. If I had to take a bet, I'd say the composer is Johann Michael Bach, though I have no proof for such an assumption.

Score is available in an Edition I made, containing all chorale preludes from this manuscript: http://partitura.org/index.php/choral-preludes-from-mus-ms-30439/
