Motet

In Western music, motet is a word that is applied to a number of highly varied choral musical compositions.

Medieval motets

The earliest motets arose, in the thirteenth century (Bent, 1997), out of the organum tradition exemplified in the Notre Dame school of Léonin and Pérotin. The motet arose from discant (clausula) sections, usually strophic interludes, in a longer sequence of organum, to which upper voices were added. Usually the discant represented a strophic sequence in Latin which was sung as a discant over a cantus firmus, which typically was a Gregorian chant fragment with different words from the discant. The motet took a definite rhythm from the words of the verse, and as such appeared as a brief rhythmic interlude in the middle of the longer, more chantlike organum.

The practice of discant over a cantus firmus marked the beginnings of counterpoint in Western music. From these first motets arose a medieval tradition of secular motets. These were two or three part compositions in which several different texts, sometimes in different vernacular languages, were sung simultaneously over a Latin cantus firmus that once again was usually adapted from a passage of Gregorian chant. It is suspected that, for the sake of intelligibility, in performance the cantus firmus and one or another of the vocal lines were performed on instruments.

Increasingly in the 14th and 15th centuries, motets tended to be isorhythmic; that is, they employed repeated rhythmic patterns in all voices—not just the cantus firmus—which did not necessarily coincide with repeating melodic patterns. Philippe de Vitry was one of the earliest composers to use this technique, and his work evidently had an influence on that of Guillaume de Machaut, one of the most famous named composers of late medieval motets.
