Musica Celestis (1990)

Musica Celestis is inspired by the medieval conception of that phrase which refers to the singing of the angels in heaven in praise of God without end. “The office of singing pleases God if it is performed with an attentive mind, when in this way we imitate the choirs of angels who are said to sing the Lord’s praises without ceasing.” (Aurelian of Réöme, translated by Barbara Newman) I don’t particularly believe in angels, but found this to be a potent image that has been reinforced by listening to a good deal of medieval music, especially the soaring work of Hildegard of Bingen (1098-1179). This movement follows a simple, spacious melody and harmonic pattern through a number of variations (like a passacaglia) and modulations, and is framed by an introduction and coda.
