interesting; I also think in terms of pitch relation. I only took a single music theory class, and actually find it boring, but I’ve always theorized about music, at least my relationship with it.
I have limited hearing. Deaf in one ear from birth and only up to 5000 hz in the ‘good ear’. Yet I never saw myself as hearing impaired; still don’t.
I can hear notes in my mind that go octaves above or below any note I’ve ever heard with my ears, just as the mind can see colors that the eyes cannot process.
