Jeanne Demessieux has produced a dozen wonderful preludes based on Gregorian chant themes. The pieces contain fairly simple pedal parts and are in a variety of styles. Titles include: Rorate Caeli (Choral Orné) * Adeste Fideles (Musette) * Attende Domine (Choral Paraphrase) * Stabat Mater (Cantabile) * Vexilla Regis (Prelude) and more.
