Access? Axis? Hmmmmmm......
Axis is what is intended, IMHO, implying something 3-D symmetrical like a globe rotating on an axis (axle?), or 2-D symmetrical figure being divided in half, a circle, a face, or an isosceles triangle, etc.
In music, real (strict) symmetry and thus an actual "axis of pitch symmetry" is possible with special arrangements of diatonic collections (dorian), certain scales (whole tone and diminished and symmetrical subsets there of) certain PC sets, and alignments of multiple chromatic scales. see, http://en.wikipedia.org/wiki/Symmetry#Musical_form for a hint of this vast world.
However, I think the concept as illustrated by Joe Satriani in one of the early posts, shows how a pitch can be used as a drone-like tonal center (pitch axis? pedal tone? drone?) while the notes that are circulating melodically and harmonically can be derived from a given mode, then another, then another, etc.
Look, any tool that helps you think in new ways when composing or improvising is all fine, as long as it focuses on the musical result, not the terms, system, numbers, machines, software, etc. Believe me, I have seen all those things imprison young musicians.
