Thanx for the description! I'm not up on theoretical names and such.......mostly because I never really studied more than what makes up scales, chords, keys, and modes. My working knowledge of theory trancends my book-learning, which explains why I've never heard of the term, Pitch-Axis.

By the description, Pitch-Axis is the basis of my sound. I teach it to all my students, though not in that technical of a description. I usually introduce the concept in a way of fundamental key-changes.
