Os mutorum. from "The Strathclyde Motets". 2 sopranos (solo or choir) and medieval harp. Réduction pour piano.

A short and simple setting of a beautiful Latin text (Mouth of the dumb...), a medieval chant from the Inchcolm Antiphoner. The first section has the duet singing the same rhythm together with triplet figures from the harp separating and accompanying their phrases. These harp phrases then form the Alleluias which the voices pick up. Simple and effective. Instrumentation : 2 sopranos (solo or choir) and medieval harp
