This slide show is a computer generated recording of Prelude and Fugue in F Major Op. 27 from Five Preludes & Fugues Op. 24-28 by Steven Monrotus.

Dedicated to Reverend Roy Gilkey, this prelude is in the 6-part form Louis Vierne taught his students for improvisation on a single free theme.  Its theme was obtained by rhythmic transformation of the Fugue's 2nd countersubject.  The related 4-voice Fugue which follows has two countersubjects and is written in triple counterpoint.

The audio clip being computer generated merely gives an idea of what this music might sound like on the real McCoy.
