I'm fine with 0-based, 1-based or anything-based arrays (I recall it being convenient solving 8queen with pascal), but for Rage-Over-A-Lost-Penny sake, music note intervals are always beyond my understanding.

Same pitched notes are called "interval 1" and there goes thirds, fifths, sevenths... All off-by-one in my base-offset-addressing mind... And then major vs. minor which creates all kinds of "aliased addresses"...

I'd really love a BASE-12 floating number representation. Like 4.00 for the middle C; Chords can be then represented by a tuple of such numbers -- major = [+0.04, +0.07] (some sequencers already do something like that and I'm far better at reading that kind of sequencer data than a sheet)

You do understand that besides thirds, fifths and sevenths, there really are seconds, fourths, sixths, ninths (same as second), elevenths (same as fourth) etc... as well, right? There even are intervals that are not named after a number e.g. the "tritone". The reason the 2nd and the 3rd note in a chord are called third and fifth is because usually chords are made with these intervals instead of dissonant intervals like seconds or fourths. It seems pretty clear you'd already know these things, so can you explain what's your issue with music note intervals?

It's that off-by-one nature of intervals that always bumps me. The difference between note a and b is (a-b+1). Calling an octave "an octave" feels to me like calling a numeric system with digits 0x0-0xf as "base 17"

And then, there's the imperial system.
