Sorry for the late post. My wife had something to attend so I had to cancel this week but had plenty to practice on.

What I did was keep running with the I-vi-ii-V7 vamp and then started to play only root-3rd movements. Never varied. Just stayed on root-3rd. All over the neck where ever the root and third of these chords showed up.

Now, another little exercise I have been doing is playing diatonic chords. For C, it would be Cmaj7, Dmin7, Emin7, Fmaj7, G7, Amin7, Bmin7b5.

Along those same lines, I would play the chord tones ascending in pitch and then descending in pitch down the scale until I hit the root of the next scale diatonically then go up that one.

That would be, in C:

C, E, G, B, A, G, F, E

D, F, A, C, B, A, G, F

and so on.
