Translated as "O blessed light, fill the hearts of all people. In work, rest; in stress, relief; in sorrow, comfort," this Latin text is featured in a gorgeous choral setting. Wonderful musical opportunities for teaching breathing, phrase shaping, pure vowel sound, and dynamic control abound in this elegantly flowing setting. A pronunciation guide is included to aid in the instruction of the Latin text. This highly recommended piece will work equally well for young treble voices or adult treble choirs.
