Me either, not far at all in fact.
Memorizing all of those variations so you can play without thinking (the only way I enjoy playing) is an enormous task.
I've always absorbed guitar learning in terms of patterns, which is a real time saver. One pattern can be used in 12 different locations, the pattern does not have to change, like it does for keyboards.
Patterns are "scale/chordal forms" in my guitar-brain world but I've never excluded any notes that lay outside those patterns. My knowledge of chords is pretty basic but I often play chords that are not basic.
It is a matter of recognizing that melody can flow through a variety of harmonic potentials and that "wrong" notes can often be exactly the perfect thing to create tension or make the lines flow as the underlying patterns shift.
Yes, that makes no sense. I could never have written a book like Ted's, it is a remarkable accomplishment.
If I had tackled it when I was in my teens and my tiny brain was not full yet, I may very well have gotten somewhere.
As it stands now, I have the entire neck as a playground and can play as "normal" as needed or toss my own freaky-deaky touches in when inspiration hits. So I am happy.
