in the prelude, the first 10 measures are played with solo pedals alone, with a recurring sixteenth-note figure, with it culminating in an unusual for the time pedal trill. the manuals then come in with the sixteenth-note figure. in the twenty-sixth measure, a 5 measure phrase of diatonic parallel sixths in the manuals and a pedal tone in the pedals occurs. in the 38th measure to the end of the prelude, the right hand plays a fast, fantasia-like passage, with fast descending scales culminating in a loud c major chord.
