I just started week 8 of this course. It has done more to help me learn how to improvise than any other lessons I have ever taken anywhere. I was wishing that Chris would do more of these for each of the positions. Then I renewed and in the Electric Practice bundle he did just that. Very similar teaching for each of the 5 positions of the pentatonic scale. As I was skimming through the lessons I picked up that each of the 5 positions of the pentatonic relate to one of the chord shapes in the CAGED system. That little tidbit all by itself is going to help me understand my fretboard immensely. It's also a good way to remember the shapes of the positions.
