Sound Therapy

“Very few in this world know to what extent phenomena can be produced by the power of the voice.  If there is any real trace of miracle, of phenomenon, of  wonder, it is in the voice.”   

Hazrat Inayat Khan (1882-1927), Sufi Master

First and foremost among instruments to produce sound is the human voice. From time immemorial, mothers have sung lullabies to their infants and children to gently “lull” them to sleep. Man uses his vocal cords for song, for ceremony and for everyday speech. From toning and droning to chanting and singing, mankind has delighted in the harmonics that enlivened sound can produce.

Man created countless musical instruments –such as trumpets and horns, pianos and organs, tuning forks and gongs, Tibetan bowls and crystal bowls, — to accompany his voice, for solo performance and in symphony with other companion instruments.  Regardless of the instrument, it has long been held as a principle of the physics of sound that it travels on waveforms. Newer research, however, suggests that sound follows a spiral pattern.  John and Analiese Reid’s visualization of sound  based on the late Hans Jenny’s (1904-1972) research provides excellent  scientific proof of how sound affects physical matter (cymatics). See the Reids’ website. You will have no doubt that sound vibrations or frequencies really do shape physical matter.


Everything in nature follows patterns.  Embryology teaches us how cells divide and multiply.  Plants, animals, humans obey these principles.

The “Therapeutic Harp” by Sarajane Williams traces the harp’s ancient history, and the groundbreaking research and developments that have led to its current use in health care settings. Vibroacoustic Harp Therapy(R)(VAHT) works by vibrating and resonating with the tissues of the body, thereby affecting physiological processes. It also affects the mental, emotional and energetic or spiritual aspects of the individual. The harp’s wide range of frequencies and overtones are capable of vibrating the dense, physical body as well as its energetic counterpart, providing multi-level stimulation and harmonization.”

Music Therapy uses melodies and rhythm.  It differs from Sound Therapy which utilizes vibration, resonance and entrainment. In physics, entrainment is “the mutual phase-locking  of two oscillators.” Entrainment is most often used to restores balance to the brain, sparking higher levels of awareness and creativity.

The voice or a musical instrument applied for healing as tones or vibrational frequencies, audible and  even inaudible tones can be used to reduce inflammation or bring more blood supply to an area of poor circulation. Toning into a painful area — a region with disrupted energy flow — can help to dissipate the blockage.  Simply, sound can increase or diminish a “charge” on an object. Physiologic effects of sound include increased oxygenation of bood and cells; it enhances the immune system via increased levels of interleukins and lymphatic circulation, decreased stress hormones (e.g., cortisol), and increased endorphins.


By definition, ultrasound is energy generated by sound waves of 20,000 or more vibrations per second–too high to be heard by the human ear. This technology developed in the 1940s and put into practice in the 1950s, is used to detect a tumor, analyze bone structure, and determine the size and health of a fetus. Ultrasound, or ultrasonic waves, can also be used to ease muscle pain. MRI, or Magnetic Resonance Imaging, represents yet another  medical diagnostic tool grounded in resonance.

In the chemistry lab at UCLA in 2002, chemist Professor James Gimzewski and Andrew Pelling discoverd “sonocytology”, the study of sounds that various cells generate. This is a completely new field of research. They hope that one day they will be able to hear specific cell sounds to detect certain diseases.

We utilize sound based on an individual’s needs and preferences. Voice Analysis is a good indicator of physical vitality; for example, it can  distinguish which body systems are stressed, which toxins are most affecting the body, and which teeth or muscle groups are potentially problematic. This is a good solution for someone who might want a more scientific approach. (They can then seek additional specific medical diagnostics.) We can prepare a tonebox to apply low-pitched sounds to the energy field to rectify imbalances. If someone prefers to feel vibrations applied directly to the body, tuning forks applied to energy centers or meridians prove very effective. Just as harmony of a musical composition induces a peaceful or relaxing state, tuning forks can be played in harmonic intervals to rebalance body, mind and spirit. In some cases, we tone directly onto an area of the body.

The late Dr. Hans Jenny coined the term ‘Cymatics’ to describe the study of wave phenomena and vibration. It is a scientific methodology that demonstrates the vibratory nature of matter and the transformational nature of sound. Jeff Volk has revived this amazing work and published the cymatics material. Visit the Cymatics website.


In 1978 Dr. Hans Cousto, a Swiss mathematician and musicologist, discovered the natural law of the “Cosmic Octave” as the link between different kinds of periodically occurring natural phenomena, such as the orbit of the planets, the weather, colors, rhythms and tones.  Astrologers and anyone interested in the power of sound and vibration will find the Cosmic Octave fascinating and inspiring. Recall that  Dietrich Gümbel, Ph.D. (Healing through the Senses: Cosmo-Therapy) bases his bio-cosmology in Cosmo Therapy on Dr. Cousto’s calculations.
