The development of music as an art form was not something that happened overnight, nor was it something that happened entirely within one musical period. In 14th century France, the freedom and sophistication of musical composition was increasing rapidly, but the musical community was still learning how to express itself. The ars nova revolution was bringing about great changes in the form and style of both sacred and secular music, while the Italian Trecento was integrating the expression of love into polyphonic composition. Nevertheless, music was still written in the form of independent motets or chansons lasting ~5 - 10 minutes, not long enough to express a broad or complex artistic message.

This first began to change in the sacred realm with the advent of the mass. In a previous entry, I commented on musical settings to individual portions of the Catholic mass, some of which date back to the early 14th century. It wasn't until ~1350, however, that the first cyclic mass (that we know of) was written. By cyclic mass, I mean a coherent work of art written by the same composer and with parts intended to be performed in a particular order. It should come as no surprise that the composer in question was Guillaume de Machaut, arguably the most important musician of the medieval period. His mass was titled, Messe de Nostre Dame (Mass of Our Lady).

Messe de Nostre Dame has six parts in total, the most interesting and impressive of which is the opening number, the Kyrie. The entire text to the Kyrie consists of a pair of two-word phrases repeated over and over again,

Kyrie eleison, Christe eleison,

which literally mean "Lord have mercy, Christ have mercy." Despite the simplicity of the text, the musical setting is extremely complex, including four voices and an isorhythmic structure. I consider this portion of the mass a must-hear for interested readers -- the voices undulate like a wave in motion, creating an effect that is both beautiful and characteristically medieval in style. The remainder of the mass is pleasant as well, though it resorts to simple parallel vocal motion to recite the more wordy texts of, for example, the Gloria and the Credo.

Whether or not Renaissance composers were even aware of this mass is unclear, but the idea of creating complete musical settings to the Ordinary of the Mass caught on fairly quickly. By the 15th century, any composer of sacred music worth his salt had composed at least one mass. The mass offers a unique opportunity to make a direct comparison between the compositional styles of different composers in different eras and I'll no doubt be returning to it many times in future blog entries.
