Watch the Changing the Progression online guitar lesson by Joe Dalton from Acoustic Blues Handbook
There are many different blues progressions. Listen to Stormy Monday, Summertime, God Bless the Child. There are many. We are not looking at those progressions here. What we have here are some simpler variations on the basic 12 bar blues progression. You will find that the “new” chords lead into the next chord. This first change is a simple one that adds life right at the beginning of the chorus. Moving right to the IV chord adds a rocking feeling, a back and forth movement.
