Let's assume, using the CAGED system specifically, I want to play the corresponding Mixolydian scales for the I and IV chord of the blues progression in G, which would be G Mixolydian and C Mixolydian. I know that using the CAGED system to make this change from the first scale to the second, I should switch to the nearest CAGED position of the scale I am switching to.
For example I could start by playing over the I7 chord using the CAGED E-form G Mixolydian scale(root on the 3rd fret of the e string), and once the IV7 chord comes around I'd switch to the A-form C mixolydian scale(Root on the 3rd fret, A string).
Basically my question is how I make this switch? What is the practical method to do so? All the material I've seen on the subject explains that I have to switch from one scale position to another, but never explains how exactly. I think I heard Martin Miller say he uses the lowest root note of the scale position as his reference point, but even so, how does that work? If was playing over the blues example, would he start playing G Mixolydian, and think "there's a C7 chord coming up, so I should find the nearest C note and apply the corresponding Mixolydian CAGED position I know that has a root on that string", or would he think "I'm currently playing in G mixolydian, the next chord change modulates up a fourth so I need to find the note a fourth away from my current root of G, then treat that new note as my new root to apply the corresponding CAGED Mixolydian scale position to it". Or am I thinking about this completely wrong? Hopefully I explained it clearly enough.
