The playful complexity of this tenor—an arbitrary (that is, “rational”) talea that mixes mensurations and undergoes diminution by half—became a typical, even a defining feature of motets in the fourteenth century and beyond. Modern scholars use the term isorhythm (“same-rhythm”) to denote the use of recurrent patterns or taleae, often quite long and cunningly constructed, that do not rely on traditional modal ordines. Motets that employ such recurrent patterns—often, as here, varied schematically on successive colores, or even within a color—are called isorhythmic motets. Despite the Greek derivation of the term, it is a modern coinage and a German one, first used by the great medievalist Friedrich Ludwig in 1904 in a pioneering study of the motets in the Montpellier Codex.
