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.
I recorded two versions of this piece. On paper it looks like a manualiter piece, but as often is the case with this type of chorale preludes, you can filter the cantus firmus and give it a separate voice. In this case I used the pedal Trumpet for that (version 1). In version 2 I just play the manualiter version. To me it sounds equaly convincing.
