Origin of Pop? Blues. Rock? Blues. Jazz? Blues.
Metal? Blues.
I only learned guitar briefly for about a year in high school. The thing I can still remember how to play is the d-minor pentatonic scale. I don't know all the fancy nerdy science-math-resonance of air theory that you do, but I deeply appreciate it.
You should really write a post on "music appreciation" with some examples of tension, dissonance, and resolution.
It's difficult for "mortals" to comprehend how it works, with band based music to identify the complex interplay of individual instruments where one might be building tension, one might be resolving, and the other might just be wandering around in search of somewhere else to be.
I love music but fail so strongly to articulate why and how I'm drawn to certain, specific things.
