Nun komm der Heiden Heiland

This choral prelude by Buttstett presents th e choral melody twice. The first time in long notes in the spoprano voice. The second time again in the soprano voice, but richly embellished. The music ends in a long run of 32th notes down the scale to the low a on the keyboard. It's easy to hear this run as a depiction of descend of Jesus from heaven to the newly born boy.
