Messe de Nostre Dame

Messe de Nostre Dame is a polyphonic mass by the medieval French composer Guillaume de Machaut, composed circa the 1360s. It employs modal polyphony and isorhythmic techniques within a unified multi-movement setting, representing one of the earliest complete mass settings by a single composer and a central work in the development of late medieval sacred music and in Machaut's liturgical oeuvre.
