This thesis examines Hildegard of Bingen (1098-1179)'s theology of music, using as a starting place her letter to the Prelates of Mainz, which responds to an interdict prohibiting Hildegard's monastery from singing the liturgy. Using the twelfth-century context of female monasticism, liturgy, music theory and ideas about body and soul, the thesis argues that Hildegard considered the sung liturgy essential to monastic formation. Music provided instruction not only by informing the intellect but also by moving the affections to embrace a spiritual good. The experience of beauty as an educational tool reflected the doctrine of the Incarnation. Liturgical music helped nuns because it reminded them their final goal was heaven, helped them overcome sin and facilitated participation in the angelic choirs. Ultimately losing the ability to sing the liturgy was not a minor inconvenience, but the loss of a significant spiritual and educational tool fundamental to achieving union with God.
