Prelude and Fugue in C minor, BWV 847

Prelude and Fugue in C Minor, BWV 847, is a keyboard composition written by Johann Sebastian Bach.

The motif consists of running sixteenth notes in the form of broken chords in both hands.

The coda begins at the 34th bar, where a sudden change of texture and tempo occurs.

In the first bar of the coda, an arpeggiated chord is followed by a rapid succession of thirty-second notes.

This new motif is repeated twice, after which a succession of sixteenth notes ends the prelude on a Picardy third.
