for soprano solo, SATB, and optional organ This is a peaceful setting of the Latin hymn text, translated by J. M. Neale. Partially based on the plainsong melody Conditur alme siderum, the music features sonorous harmonies, subtle time changes, and fluid choral homophony, with a beautiful soprano solo that floats over the other voices. The work may be performed unaccompanied or with organ doubling the voices (excluding the solo line). It is suitable for both general use and Christmas.
