These exercises are based on a standard blues chord progression:
E7/E7/E7/E7/
A7/A7/E7/E7/
B7/A7/E7/E7
I7 / I7 / I7 / I7 /
IV7 / IV7 / I7 / I7 /
V7 / IV7 / I7 / I7
The goal here is to learn different patterns. If you play a blues session, the chord progression is repeated over and over again, so be prepared with different patterns to come up with.
