Messe de Tournai

The Tournai Mass is a polyphonic setting of the mass from 14th-century France. It is preserved in a manuscript from the library of the Tournai Cathedral. The Tournai Mass comprises six movements, each of which are for three voices. * The Kyrie is written in Franconian notation, and is stylistically typical of mid-to-late 13th century practice. * The Gloria has freer rhythmic interplay than the Kyrie, characteristic of Ars Nova developments.
