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. The recording was done with the Hauptwerk software and the sampleset the Bader organ in the Walurgiskerk, Zutphen, made by Sonus Paradisi.
