They are not parallel. One actually *is* frequency, while the other
expresses pitch in relation to a scale.
It's like comparing inline code with calls through function pointers,
basically.

Yes, but that's not the point. And 12tET is essentially irrelevant to
this discussion (now, even *I* say that! ;-) - it just happens to be
what most people use most of the time. (Or is it? I'm thinking that
there may be some rather significant cultures where this is not
true... Unless they're all brainwashed by our 12tET music, we may
eventually be outnumbered!)
