The Messe de Nostre Dame consists of 5 movements, the Kyrie, Gloria, Credo, Sanctus, and Agnus Dei, followed by the dismissal Ite, missa est. The tenor of the Kyrie is based on Vatican Kyrie IV, the Sanctus and Agnus correspond to Vatican Mass XVII and the Ite is on Sanctus VIII. The Gloria and Credo have no apparent chant basis, although they are stylistically related to one another. Machaut's Messe de Nostre Dame is for four voices rather than the more common three. Machaut added a contratenor voice that moved in the same low range as the tenor, sometimes replacing it as the lowest voice.
Unification
In the liturgy of the Mass, the items of the Ordinary are not performed consecutively, but are separated from one another by prayers and chants. Machaut's unification of these items into an artistic whole is the earliest instance of an Ordinary of the Mass setting that is stylistically coherent and was also conceived as a unit. This gesture imposed on the Ordinary a previously unconsidered abstract artistic idea, and potentially influenced composers throughout the ages to continue setting the Ordinary to stylistically coherent music.
Purpose and style
Machaut composed his Messe de Nostre Dame for the Cathedral at Reims where he served as a canon, a permanent member of the clergy. According to a rubric found at the Cathedral, it would have likely been performed for the Saturday Lady Mass. Some scholars hypothesize that, contrary to popular belief, Machaut did not actually come to work for the Reims Cathedral until the end of the 1350s, composing the mass as an act of devotion and dedication marking his arrival in the precinct. In conformity with the wills of Guillaume and his brother Jean, also a canon at the Cathedral, the mass was believed to have been transformed into a memorial service for them following their deaths. However, neither the specific nature of its performance nor the service the Mass was prepared for has been conclusively ascertained. It is possible that Machaut was familiar with the Tournai Mass, an even earlier polyphonic 14th-century mass setting in which each movement is believed to have been written independently by different composers. The Gloria and Credo of the Messe de Nostre Dame exhibit some similarities to the Tournai mass, such as textless musical interludes, simultaneous style, and long melismatic Amens. The other four movements of Machaut's mass are composed in motet style with mass text.
Recordings
It is often stated that the Messe de Nostre Dame was first recorded by Safford Cape in 1956 for the Deutsche GrammophonArchiv Produktion Series. However, earlier recordings were made by the Dessoff Choirs under Paul Boepple, in 1951; and a partial recording by Les Paraphonistes de Saint-Jean-des-Matines under Guillaume de Van in 1936. More recent recordings include the following:
