Harmonics

n. study or theory of musical sounds; healing method of chanting that was developed and practiced by Tibetan monks

n. overtone, secondary tone which is higher than the primary or fundamental tone (Music)

In acoustics and telecommunication, the harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. For example, if the frequency is f, the harmonics have frequency 2f, 3f, 4f, etc. The harmonics have the property that they are all periodic at the signal frequency. Also, due to the properties of Fourier series, the sum of the signal and its harmonics is also periodic at that frequency.

(n.)
Secondary and less distinct tones which accompany any principal, and apparently simple, tone, as the octave, the twelfth, the fifteenth, and the seventeenth. The name is also applied to the artificial tones produced by a string or column of air, when the impulse given to it suffices only to make a part of the string or column vibrate; overtones.
  

"Transformative" and "curative" mode of chanting developed and practiced by Tibetan monks. Proponents associate particular sounds with specific bodily "energy centers."
