This is an all-male vocal recording, including chant (Propers) and polyphony (Ordinary). The Mass of Tournai is early 14th century, a decade or so before that of Machaut. Some have argued that it does not show a unified design, and so Machaut's setting is the first unified mass cycle. The respective unities are not clear - at most it is a matter of degree - although it is not known whether this mass was composed by one composer or many. At any rate, it is the first mass cycle declared as such. The concluding Ite missa est leads into a true motet, with different texts in the two upper voices.
