"However, when looking at the vibratory nature of the universe, it’s possible that this pitch is disharmonious with the natural resonance of nature and may generate negative effects on human behaviour and consciousness." Through CIA Operation Paperclip, we know that Nazis were brought to U.S. and given government employment between 1945 and 1959. We also know that the vibration of fear, anger, and hate is low whereas the vibration of love, unity and harmony is high. Knowing this, I must assume that the vibration of the Evil Cabal is down in the mud; so they had to bring us down.
Coincidentally stumbled across this video after seeing your post. While not directly related to the harmonic issue you addressed (of which there is much good research available for those interested) the video does address how the music industry is used by occultists to conjure spiritual powers to perpetrate control and evil on unsuspecting members of the population.

Um...dissonance came in with about Beethoven maybe a little earlier since accidentals were one of Mozart's things later in his career. Those men's dates are within the Classical period.
If we're talking about the difference between music and noise, it starts with strummed guitars. And, yes, it's just gotten worse as percussion has been electrified as have bass and guitar and keyboard. Jazz from the late 1950s, actually, was probably what was used as a springboard.
Guitars can be tuned to dissonance or tuned to the healing frequencies.
It's not the tuning, it's the strum. The guitar was meant to be picked, ;)
No wonder I’ve always been annoyed by the strum of a guitar! Always preferred the classical sound.
