The audio portion of this slide show is a computer generated recording of Prelude & Fugue in a minor Op. 25 from Five Preludes & Fugues for Organ Op. 24-28 by Steven Monrotus.
Dedicated to technician Marlin Mackley, this piece is a 4-voice Fugue with 2 countersubjects written in triple counterpoint paired
with a related Prelude with one theme developed in the 6-part form for free improvisation as taught by Vierne.
audio clip being computer generated merely gives an idea of what this music would sound like on the real McCoy.
