If you want to get some more beef into your blues; play the Power Blues Progression. If you look closely, the E in the progression is actually the E Open Chord and you are shuffling to the A Open Chord. In the A Progression you are going from an A (in the E shape) to a D (in the A shape). In the B Progression you are going from a B (in the E shape) to an E (in the A shape). We will learn about Chord Shapes in a later lesson.
