Chorale Prelude 'Kommst du nun Jesu vom himmel herunter', BWV 650
Johann Sebastian Bach published his Wer Nur den Lieben Gott, BWV 647, around 1748 as part of his Six Chorales of Various Kinds. These six works for organ are based on cantatas. They provided an approachable version of Bach's cantatas through the more accesible medium of keyboard music, and the fact that Bach chose to edit these (while the rest of his cantatas remained largely unpublished during his lifetime), says something about the musical statement that they represented. This particular prelude is based on alto solo of the second movement of cantata Lobe den Herren, den mächtigen König der Ehren, BWV 137.
