I'll add that music is probably a form of synesthesia that all humans have inherited. Albert Einstein noted that Mozart was math. Why would math be rationally related to the
perception of music except for some strange wiring in our brains? Almost all birds can sing, but they don't produce what we would call music. Mammalian vocal cords can also produce a vast range of sounds, but we wouldn't call any of their productions music, either. Yet we produce music with our voices, our hands (on a vast array of instruments), on our computers, and have used just about everything capable or producing sound. It's as if we're processing sequences of notes (again, another invention of ours related to our bizarre perception of music) on an emotional level, which really makes no sense at all unless we're all processing sensory inputs in illogical and irrational ways, like seeing colors associated with numbers and letters.
But since everyone has the same defect we mark it as normal and instead label those who don't possess it as deficient, tone deaf, autistic, and the like.
So let us just note that those with synesthesia live in a somewhat richer world which makes little or no sense to the rest of us, just like my cat and rabbits make no sense of all the emotionally uplifting music I play on my laptop.
They can't perceive how the mathematics of changing patterns of sound frequencies could be emotionally uplifting,
and we don't understand it either. But since we all perceive that it is so, and since we all love the result, we don't question how our sensory wiring could be so screwed up to produce such an effect.
It's much like the way the crew of the Enterprise failed to appreciate Wesley's perception of space and time. He could hear and see and feel things in ways that made no logical sense to the minds that weren't similarly miswired, just as his character made no sense to minds that weren't attuned to the creative genius of having a whiney kid at the helm. Let's be honest. If we had inherited the same perceptual abilities as the writers, Wesley would've been the show's Anakin Skywalker.
ETA: Yes, I totally went there.
