Sound Healing or Therapy is a method of using selected sound vibrations that create resonance for a specific physical and spiritual effect. It may be used for overall relaxation or to address specific physical or emotion conditions. 

Sound therapy can be as simple as repeating an OM mantra during meditation, or as immersive as a sound bath of pulsing chakra tones and deep gongs (OMG!). It is often used along with other spiritual practices such reiki and meditation.
