{{Listen|filename= Machaut - Missa Notre Dame - Kyrie.ogg|title=''Kyrie'' from the ''Messe de Nostre Dame''|description=By Guillaume de Machaut, midi instrumental version|format=[[Ogg]]}}

Machaut's cyclic setting of the Mass, identified in one source as the ''[[Messe de Nostre Dame]]'' (''Mass of Our Lady''), was composed in the early 1360s probably for [[Rheims Cathedral]].  While not the first cyclic mass – the [[Tournai Mass]] is earlier – it was the first by a single composer and conceived as a unit.  Machaut was probably familiar with the Tournai Mass since Machaut's Mass shares many stylistic features with it, including textless interludes.

Whether or not Machaut's mass is indeed [[cyclic mass|cyclic]] is contested; after lengthy debate, musicologists are still deeply divided. However, there is a consensus that this mass is at best a forerunner to the later 15th-century cyclic masses by the likes of [[Josquin des Prez]]. Machaut's mass differs from these in the following ways: (1) he does not hold a [[tonal centre]] throughout the entire work, as the mass uses two distinct [[musical mode|modes]] (one for the Kyrie, Gloria, and Credo, another for Sanctus, Agnus and Ite missa est); (2) there is no extended melodic [[theme (music)|theme]] that clearly runs through all the movements, and the mass does not use the [[parody mass|parody]] technique; (3) there is considerable evidence that this mass was not composed in one creative act. The fact that the movements were placed together does not mean they were conceived as such.{{sfn|Keitel|1982|loc={{Page needed|date=March 2014}}}}

Nevertheless, the mass can be said to be stylistically consistent, and certainly the chosen chants are all celebrations of Mary, the mother of Jesus. Also adding weight to the claim that the mass is cyclic is the possibility that the piece was written or assembled for performance at a specific celebration. The possibility that it was for the coronation of [[Charles V of France|Charles V]], which was once widely accepted, is thought unlikely in modern scholarship. The composer's intention that the piece be performed as one entire mass setting makes the ''Messe de Nostre Dame'' generally considered a cyclic composition.
