963Hz reduces to 9. So does 432, 528, and 396. The pattern holds across the entire solfeggio frequency set. The octave of C vibrates at 528 cycles per second, G at 396. The original circular church measured 39.6 feet across. Multiply that by ten and you have 396, the vibrational rate of G. Add a zero to 528 and you have 5,280, the number of feet in a mile. The historical record gives no clean origin for the mile. It is simply very old. The question is whether these convergences are coincidence, or whether the ancients understood number, sound, and space as a single unified system.
