I get this question a lot as well!
Sound healing isn’t new. Sound Healing is more of an umbrella term for ancient healing practices all over the world, both spiritual in nature, and not spiritual. Many Eastern spiritual traditions use these instruments for ceremony and healing thousand of years ago. Sound Healing practices span over every continent and continent and culture, and so it is the responsibility of the practitioner to not only know the practical application of the instruments in our modern day, but also maintain the integrity and ethic of the practice from what if came.
It is worth mentioning that we may also categorize ultrasound and frequency therapy as an accepted and frequently medical intervention. While a Sound Healing Practitioner, Therapist, or Facilitator may not use these interventions, it is using vibration and frequency as a tool for healing.
