Just intonation vs equal temperament
Why pure ratios sound “sweet,” why equal temperament won keyboards, and how this intersects 432 debates.
Dual lens. Science pane = measurable / historical fact pattern.
Mystic pane = living myth, ritual, and cultural meaning. BBM is not a medical device.
◈ Science
Just intonation favors simple frequency ratios in a key; 12-tone equal temperament (12-TET) compromises pure intervals so all keys are usable. Neither is “more natural” in absolute physics — both are cultural technologies. Beating between slightly impure intervals is measurable and audible.
✦ Mystic / Mythos
Some healing-music schools prefer just intervals as “purer geometry.” Listeners often describe them as more restful in drones. That’s aesthetics + psychoacoustics of beating, not automatic enlightenment.
Operator tip. Headphones for binaural difference tones.
Musical pitch (432 / solfeggio fundamentals) is a different control axis from beat frequency (delta→gamma).
