What is the isorhythmic motet and why is it important?
The isorhythmic motet is a piece of the ars nova that employs isorhtyhm, which uses lengthy passages in identical rhythms and distinct melodie. Isorhythm reveals the culminations of ars nova (1300-1400) musical ingenuity. The repeating rhythm provided unification of pieces, replacing the unification formerly brought by the droning Gregorian chant during Medieval times/ars antiqua (1100-1250).
