This haunting Advent carol has held a revered station for more than five centuries and has been arranged and reset by composers throughout the ages. Beginning in Latin, Paul Doust presents the tune with a soloist over a choral pedal point, with some subtle note colorations added from other voices. As the choir continues in English the harmonies thicken in lush tones. The “rejoice” section emerges victoriously each time it occurs. Advanced church choirs and college choirs will enjoy this piece, medium in difficulty.
