I’ll never forget the musical journey I pursued after checking out Gavin Harrison’s method book Rhythmic Perspectives. In one section, Harrison presents an in-depth study on multilayered polyrhythms and discusses hearing the groupings from each rhythm’s individual perspective. This particular chapter inspired me to explore four-layer polyrhythms—such as groupings of three, four, five, and seven played simultaneously—while trying to hear the pulse from each of the separate groupings’ perspectives.
