This video demonstrates a little exercise I made up a while ago for getting to grips with the CAGED system.

It takes a short time to understand what CAGED is about, but a little longer to actually experience it as part of your playing.

This exercise is pretty simple, it's a blues progression that uses all 5 shapes of the 7th chords.  It's a way of getting the shapes under your fingers, and also, learning the flow from one shape into another in a seamless way.
