Sound healing is used, specifically, with certain acupuncture treatments. The vibration assists the needle to vibrate at a deeper level.
Sound has been used for healing since the beginning of recorded time and longer. Everyone responds to music, from pre-natal experience through to our death. We respond to rhythm, melody, and harmony. The way we respond is as much because of the music as it is from our individual life experience of what music feels like to us.
There are references to sounds effecting the health, by Taoists who discovered the effects of qi and emanating sound to enhance and spread qi throughout the body. The Egyptians used sound for healing as well as Tibetans, American Indians and Shamen of every culture.
