Von Gott will ich nicht lassen

Johann Michael Bach was second-uncle (and then posthumously) father-in-law of Johann Sebastian Bach, because he was the father of Bach's first wife Maria Barbara. He came (like almost any Bach) from a musical family, his father Heinrich Bach and his brother Johann Christoph Bach were both active organists and composers. He was born in Arnstadt and became the organist and town clerk of Gehren, where he lived until his death.

This chorale prelude on the hymn Von Gott will ich nicht lassen can be played on manuals only, but it's also possible to play the cantus firmus in the pedals (using a 4' stop).
