Canonic Variations on "Vom Himmel hoch da komm' ich her"
The Canonic Variations on "Vom Himmel hoch da komm' ich her" (From Heaven above to Earth I come), BWV 769 is a well-known piece of music for organ by Johann Sebastian Bach.  An organ with two manuals (keyboards) and pedals is needed to play this work.  There are five “variations”.  All the music is based on a Christmas hymn called “Von Himmel hoch” which was very well known to the people who went to the Lutheran church where Bach was organist.
