About the Solfeggio frequencies...
The Solfeggio frequencies refer to specific tones of sound measured in Hertz. These cycles per second vibrations are believed to promote various aspects of body and mind health. The Solfeggio frequencies are reputed to date back into history and are said to be the fundamental sounds used in both Western Christianity and Eastern Indian religions, once chanted by the Gregorian Monks and in ancient Indian Sanskrit chants.
Physician and researcher, Dr. Joseph Puleo, rediscovered the Solfeggio frequencies in the 1970s, bringing their touted benefits into public awareness.
Many in the restorative and healing communities believe that these specific tonal frequencies can profoundly affect the conscious and subconscious mind in order to stimulate healing and promote vitality.
The numbers 3, 6, and 9 are fundamental vibrations throughout the solfeggio frequencies.
