Watch the A Form: Framing Exercise online guitar lesson by Dave Celentano from CAGED Commander
Framing chord tones with adjacent scale tones is a fantastic way to familiarize yourself with the most sturdy notes in the scale. This exercise stays strictly within the frame of the 'A form' major scale. Practice this with a metronome at a tempo slow enough to play it flawlessly. Mastering the scale patterns in this course will require a bit of practice and these exercises are designed to get you there, but you've got to own them (be able to perform them in your sleep).
