There is a profound art to sound that we have not yet rediscovered. Mantra, the study of specific sounds has largely lost the understanding of tone. There are references to it in Sanskrit but it’s clearly not understood. This may partly have been influenced by the paternalization of Sanskrit- the shift to men as the carriers of the language.
Indian Ragas, melodies which are aligned to certain times of the day or for certain effects have shifted to the easier western polyphonic scale and away from natures pure tones. The polyphonic scale calls for tones of equal frequency increments that allow chords, but it falls away from the higher importance of natural sequence.
Sound healing and technologies like Rife use specific frequencies or tones for a given effect. The western ear is a bit biased by the same polyphonic scale though. And without the right letter for the tone, a piece is missing.
Nature itself creates first through vibration. Correct vibration is in tone and pronunciation and sequence. While there may be some value in listening to a pure tone, the real power for change is in a sequence of unfolding.
Just consider Aum, the pranava mantra or first sound, the sound from which all sounds arise. It is always experienced as having one of several very specific tones. (depending on what you’re hearing it with) But this is just at the very beginning. To have expression, Aum has to break out into sequence – letter-tones in a specific unfolding.
The true art of sound healing and powerful mantra will come when these are merged – correct tone and correct pronunciation. And then correct sequence.
PS – coherent fields? That’s another technology we’ve lost that is soon to be rediscovered. The flowering of new understanding will be unprecedented.
