Just finish this two important studies of the fretboard. Highly recomended for guys like me who thought that I know everything. First studies is the relative mode of the mother scale, while the Second is the parallel way of studying it. What is important is the "play and hear" or familiarity of the sound of each mode. This gives me now the main reason why I should practice daily. I will add simple chord(s) to each mode for that sound/scale to be embedded into me.

One question: Is this what we call "Pitch Axis Theory"? I read it in the forum. It was Bela Bartok who created it, not Joe Sartiani. I would appreciate it if there is a study of this on GT.
