The practice of mapping triads and melodies to a Cartesian Plane is a fundamental component of my composition and improvisation practice. This visual mapping allows for a visualization of various traids and scalar patterns found in Western Harmony. When utilizing this system, I am able to create music that can be polytonal, classical, or modern. One surprising application of the ear training method found in the book has been for the guitar.
In all, I recommend this book, CMOCAS, to anyone who wants to approach multiple styles of musics through triad and scale organization. Through a study of works and consistent improvisation, this can be achievable through the exercises found in this book. Below, one can purchase the book from Amazon.
