This was fun reading. I was amazed!
Having said that, as a musician, I find all frequency relevant, and enjoy a bit of varietal drift from time to time, tuning to the moment.
This thread discusses what we listeners want, if we consider not being seperate but unified with our tools the harmony will develop and take place on its own.
The base of the pyramid is 440 Royal Master Cubits, approximately 230. The only number that could in principle have some intrinsic importance are relations between quantities of the same units, since that would be a pure numbers and not a relationship between two distinct units, which will always be arbitrary" But the second is not arbitrary is was derived by the Babylonians.
In the Islandic Grimnismal, drawn from the poetic Edda composed between the 8th and the 12th centuries, the Walholl or Walhalla, palace of the paradise of Wotan, or Odin, is structured by 540 gates.
The main differences between this and the historical Pythagorean system is that while Renold similarly tunes the white keys by powers of 3: His name is Samuel "Sam" Milligan haha. I myself have an old Tibetan bowl which is exactly design to stimulate the Heart Chakra. Please look it up. It sounded perfectly fine. Furthermore do you really think the music industry wants people to know any sort of truth.
Similarly, University of Conneticut neuroscientist Dr. Listen Now. What is it about electronic music that makes it impossible for some to stand still?
Sound is as visual as taste, and touch and to a great extent has not been given it's rightful place in our existence in quite some time. They would probably like it better if the instruments were made to resonate at 432, but at this point it seems impractical, that is if you want to be able to easilyu play with others.
But with all these coincidences I am prone to believe that there is a harmonic series of ultra low frequencies that permeate existence and that with a low frequency generator we can produce an interference pattern which reveals them; and that before Equal Temperament and the 440hz arbitrary standard of today, others before us found a way to discern these frequencies and based their music and their philosophy upon them.
I believe the great composers would have been disgusted to be subjected to such limitations about their work.
See my blog, HarmonicsOfNature. Thank you so much for injecting a researched and informed perspective on this.
But the thing is that you can't never have an exact frequency. It's kind of irrational. The brain is on a constant yo-yo, being pinged at by different frequencies:
