The universe is information. Information, like number, is ultimately a resonant property of mind. Information is energy structured according to the receiver for which it is intended. A transduction has occurred - a transformation of sound, one kind of information, into emotional energy, another kind of information. All energy possesses transductive wave properties.
All wave property is susceptible to being transmitted resonantly as frequency overtones.
A coherent cycle of frequencies is an octave, and in all octaves any tone can be sounded to produce its overtones in other octaves. Add to this the fact that any wave property can be transduced from one form to another through a particular medium, such as quartz crystal , and you have the basic principles underlying harmonic resonance. This implies that between the cells of the body there is a universal system of communication operating at speeds ranging between those of sound and light .
