The convent of Port-Royal in Paris, which practised the Jansenist doctrine, commissioned some musical masterpieces, including this fine mass by Charpentier. Its apparent austerity is offset by writing that is full of feeling and finesse.
Charpentier:
Messe pour le Port-Royal H.5
Hymn - Veni creator pour un dessus seul au catechisme H.69
Magnificat pour le Port Royal H.81
