Prelude "Tota pulchra es"

Recently I wrote three chorale preludes to "Nun komm der Heiden Heiland", based on a similar composition by Walther. And I posted a recording of the resulting three choral preludes here: http://www.contrebombarde.com/concerthall/music/36140

As a result of the publication of these three works I was contacted by someone, who was looking for help to "compose a 40 sec piece to end a choral piece (with a bang)". I first wrote something that was more suitable as a prelude and with not a "bang" at all.

Though I quite like the result, played here, I think I'm not yet finished with this music. See (and listen to) the next upload.
