A writer, encyclopedist, healer, and the founder of two monasteries, Hildegard composed a great deal of plainchant liturgical music, including antiphons, responsories, sequences, and hymns. Recordings of her work have topped the Billboard charts several times over the last two decades and helped to spark a craze for music of the period.
The new work depicts a meeting of twelve cardinals considering whether Hildegard should be canonized.
