There’s a lifetime of knowledge in just the first 6 pages of this book! It provides a fundamental understanding of the history and principles of harp therapy, vibroacoustic therapy and VAHT (Vibroacoustic harp therapy.) The harp is made of natural materials that resonate with the human body. The use of live music provides an obvious benefit because music delivers analog, musical information through a wide frequency range. This and much more, including case histories and pilot studies are found in this very informative book. Emotional shifts, deep relaxation, overtones and other quality information can be subtly delivered through music. To put it simply, this book is just packed with great and worthwhile information!
