In the last section, marked "forte", the pedal part plays the chorale tune upside down. At the very end, as the music rises to a climax, it repeats the last line of the chorale tune, finishing on the lowest pedal note: the bottom C. The hands meanwhile play on the same manual. There is a “stretto”: all the voices start the tune (or a version of the tune) quickly one after another. At the very end we hear the BACH motif again.
