I've been a sceptic re the Mozart Effect because of the Money Effect, but I also know from personal experience the power of music to heal and stimulate and soothe. Don Campbell has also edited a book I'm now reading entitled, "Music: Physician for the Time to Come" and it's fascinating- runs the gamut from technical/scientific to far-out woo-woo. But the studies on harmony, vibration, and the human body and psyche fascinate me.
