The audio portion of this slide show is a computer generated recording of Prelude Internationale in Bb Major Op. 5 from Ten Pieces for Organ Op. 1-9 by Steven Monrotus.

Dedicated to the memory of world class organist/composer Louis Vierne, this quiet 4-voice Prelude for hands only, playable on a piano, develops a single free theme in the 6-part form for improvisation as taught by Vierne.

The theme for this Prelude is derived by rhythmic transformation (same pitches in order, different note values) of the cantus firmus from the Op. 4 Variations.

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