This video is a cymatic version of Sound Frequencies in Water: A=440 Hz & A=432Hz using sine, square & sawtooth waves. It has been said that music tuned in A=432 Hz is more beautiful and harmonious to the ears and induces a more inward experience where music tuned in A=440 Hz is more outward, mental experience which is projected outwards. This test is comparing the frequencies of A=440 Hz and A=432 Hz generated using sine, square and sawtooth wave patterns.
