The universal appeal of music, which is composed of combinations of sound frequencies, demonstrates the intimate relationship we have with sound. Both sound and color therapies work through the principle of resonance. Resonance is the tendency of a substance or system to vibrate more strongly when exposed to some frequencies more than others. The frequencies that produce the strongest vibrations in the substance are considered to be its resonant frequencies. Even small amounts of energy can produce high amplitude vibrations when a system is exposed to its resonant frequency.
Sound healing is very powerful. It is applied in various ways including musical recordings, Tibetan bowls and gongs, toning and chanting, drumming and the use of various forms of therapeutic equipment. Sound is well known for opening closed and blocked physical and emotional energies. I use various forms of sound healing and shamanic drumming in my healing work, as is appropriate.
