This is a modern musical adaptation of the Office of Compline, one of the canonical hours in Christian liturgical tradition. Compline is the final church service of the day, intended to be recited or sung before retiring for the night. The chants are adapted from the Liber Usualis, a foundational book of Gregorian chant containing the most commonly used liturgical texts and chants for the Catholic Mass and Office. This adaptation represents a continuation of a musical tradition dating back many centuries, now set in modern English for contemporary liturgical use.
