Prelude and Fugue in C-sharp major, BWV 848

Prelude and Fugue in C sharp Major, BWV 848, is a keyboard composition written by Johann Sebastian Bach.

Later on in the piece, the semiquaver line splits between the hands before ending with a short Coda in an improvisatory manner.

The three-voice fugue is unusually void of the commonly used fugal devices, such as augmentation, diminution, inversion, pedal point or stretti.

One of the countersubjects is constructed with running legato semiquavers, whilst the other consists of longer note values.

The fugue has an extensive sequential episode which develops through related keys before the reappearance of the three voices.
