Nun komm der heiden Heiland

Just another prelude on this chorale. It's not exactly the first one this year, but I thought it too beautiful not to typeset, play and upload it.
It is one of three preludes Walther wrote on the theme of “Nun komm der heiden Heiland”. It presents the chorale melody in all four voice. As counter subject for the first fragment of the melody Walther uses both the other fragments. Thus he creates a texture in which the melody fragments twirl around each other, in both more or less plain form and heavily embellished. One needs the score to really hear what’s going on.
