_Harmonic Experience_ offers a comprehensive view of music that reconciles the ancient harmonic system of just intonation with the modern system of 12-tone equal temperament. Saying that “the rules of music were not formed in our brains but in the resonance chambers of our bodies,” W.A. Mathieu recognizes the pronounced need for an experiential kind of teaching that reconnects the way we _think_ music with the way we do music. Mathieu provides over a thousand musical examples and diagrams to illustrate the ideas he presents, allowing readers to reach a deeper level of response, to hear existing musical compositions more clearly, and to become thoroughly engaged in their own musical creativity.
