Prélude, Choral et Fugue (Franck)

Prélude, Choral et Fugue, FWV 21 is a work for solo piano written in 1884 by César Franck. This work is an exemplar of Franck's distinctive use of cyclic form.

Structure
As the name implies, it comprises three movements: a prelude, a chorale and a fugue. The interconnectedness and thematic relationships (particularly the cyclic recall of the Prelude and Chorale in the Fugue) make this an unorthodox example of double-function form.

It uses a Chromatic fourth motif in the Chorale and the Fugue. The Prelude starts in B minor. The Fugue returns to B minor, but ends in B major.

In popular culture
The work plays a prominent part in the soundtrack of the film Vaghe stelle dell'orsa... (aka Sandra or Of a Thousand Delights), directed by Luchino Visconti and starring Claudia Cardinale.
