This is the first of two chorale preludes I've recorded on "Mache dich, mein Geist, bereit" or "Straf mich nicht in deinem Zorn."
However you register it, or whatever tempo you play it, I feel this setting is better suited to the first of these chorales.
I know the tune (without the repeat) better as Würtemburg, used for the Easter hymn "Christ, the Lord, is risen again!"
The CF appears in canon in the pedal and right hand with passagework in the left hand (and an occasional alto part at cadences).
