Dr. Hans Jenny, a Swiss scientist who studied the effects of sound upon organic matter, called the work cymatics, or the study of waveform phenomena. Using various organic substances vibrated at different frequencies, he found repeatable patterns that represented cellular growth, mandalas, and microscopic life forms. From his work it has been proposed that sound creates form and changing frequencies affect form at a cellular level. Now, using laser technology, physicists are also finding that harmonic intervals produce perfect geometric shapes, reinforcing the idea that vibration underlies all form.

Dr. Andrew Weil, author, lecturer and founder of the Program in Integrative Medicine in Tucson, Arizona, states that "The new science of psychacoustics -- the study of the effect of music and sound on the human nervous system -- shows that [frequency] can relieve pain, help stroke patients, and benefit other conditions."

Dr. Herbert Benson, M.D., of the Mind/Body Medical Institute at Boston's Deaconess Medical Center, having studied the effects of chanting mantras on human physiology, found that repeating a single syllable or word produced measurable changes in energy consumption, respiration rate, heartbeat, metabolic rate and pulse, as well as an increase in alpha brain waves.
