Reddit reviews Healing Sounds: The Power of Harmonics

So my first suggestion would be Stalking the Wild Pendulum. This book really introduced me to the concepts of resonance beyond just using it in terms of musical instruments. It was written by a guy that didnt even pass kindergarden, but grew up to be a very respected physicist in his field. Therefor, he knew to convey very advanced concepts in laymen's terms.

Secondly, I would recommend Healing Sounds. Once I gained a an understanding for resonance, I (eventually) came across this book, which teaches you how to use it. Very cool stuff
