Polyphonic metric structures that depend on a common metronomic time grid -- a grid defined by the smallest common duration called at CNMAT the "tatum." The tatum is the smallest measurable duration and is a common multiple of all larger durations. Most "groove" based musics are dependent on such a structure. By contrast, music that features aperiodic time structures are rarely considered polyrhythmic.
