Wikipedia defines polyrhythm as “the simultaneous use of two or more conflicting rhythms” and reports “Sub-Saharan instruments are constructed in a variety of ways to generate polyrhythmic melodies. Some instruments organize the pitches in a uniquely divided alternate array, not in the straight linear bass to treble structure that is so common to many Western instruments such as the piano, harp, or marimba.”
