The first book in a four volume set of organ pieces based on Gregorian chant melodies. The entire collection is keyed to the three-year lectionary shared by all liturgical denominations and will, when complete, present chant-based music for every sunday and major feast of the liturgical calendar. Organists serving non-liturgical churches will find these collections an invaluable resource for service preludes and offertories (there are a few postludes, too).
