Review Quotes:
"Ernest Levy's idea [was that] any chord in any key, has a reflection, a polar opposite ... based on rotating every single note around the axis of the key center." - Jacob Collier
"The extreme symmetry that Levy is dealing with ... reminds me of some of the work I've done as well as elements of Bartók's work, Henry Threadgill's work, W.A. Mathieu, Howard Boatwright, Schwaller de Lubicz, and ancient Egypt, Pythagoras, Plato, and the work of the ancient Greeks, Babylonian ideas of reciprocity and the work of Umayalpuram Sivaraman and other related Vedic symmetrical ideas." - Steve Coleman
