Motet for 3 voices Notre Dame Organum
Performed and recorded by Dr. Stephen Duncan
Organ
The earliest motets arose in the 13th century from the organum tradition exemplified in the Notre-Dame school of Léonin and Pérotin.[8] The motet probably arose from clausula sections in a longer sequence of organum. Clausulae represent brief sections of longer polyphonic settings of chant with a note-against-note texture. In some cases, these sections were composed independently and "substituted" for existing setting. These clausulae could then be "troped," or given new text in the upper part(s), creating motets. From these first motets arose a medieval tradition of secular motets. These were two- to four-part compositions in which different texts, sometimes in different vernacular languages, were sung simultaneously over a (usually Latin-texted) cantus firmus usually adapted from a melismatic passage of Gregorian chant on a single word or phrase. It is also increasingly argued that the term "motet" could in fact include certain brief single-voice songs.
The texts of upper voices include subjects as diverse as courtly love odes, pastoral encounters with shepherdesses, political attacks, and many Christian devotions, especially to the Virgin Mary. In many cases, the texts of the upper voices are related to the themes of the chant passage they elaborate on, even in cases where the upper voices are secular in content. Most medieval motets are anonymous compositions and significantly re-use music and text. They are transmitted in a number of contexts, and were most popular in northern France. The largest surviving collection is in the Montpellier Codex.
