The Cosmic Octave: Origin of Harmony

This is the best book that I have ever found on the spiritual essence of frequency. The webpage of the author has much of what this book covers, but this book is the most condensed perfect version to start.

A beautiful book with clear illustrations. It is a book that has really good explanations.

Fascinating book. If you are a musician or a sound healer. There is some amazing information.

Fabulous book, a must for sound healers or those wishing to learn about the magic of music.

Very interesting indeed! An offering of perspective for anyone that has an interest in the music of the spheres, vibration, sound healing, and particularly the planetary healing forks and gongs. Good stuff!
