Shamanic drumming or Rhythm healing relies on the natural law of resonance to restore the vibrational integrity of body, mind, and spirit. Sound waves have the ability to impart its energy to a substance such as wood, metal, or the human body, making it vibrate in sympathy. When we hear drumming, our living flesh, brainwaves and spiritual energy centers begin to vibrate in response.
