In 1953 all music was tuned from 432hz to 440hz. This took a key fundamental component of music- studies have shown 440hz actually causes the brain to become agitated.
432hz however has substantial healing benefits which ancient civilizations from Egypt to Greece and from modern-day Musical Healers like Jimi Hendrix, Bob Marley, Prince, John Lennon, and more! Mystech's Resonance Technology has been used to create a way to filter Music back to 432hz, allowing you to feel it and reapply the "Muse" part of Music.
"A=432 Hz, known as Verdi’s ‘A’ is an alternative tuning that is mathematically consistent with the universe. Music based on 432Hz transmits beneficial healing energy because it is a pure tone of math fundamental to nature." - Brian T Collins
