Watch the Chromatic Fantasy online guitar lesson by Jeff McErlain from 50 Blues Guitar Licks You MUST Know
There is an old saying in jazz, “there are no wrong notes, just poor choices.” The problem is when you make a poor choice on the gig! OK, this kind of thing takes a long time to master but you have to start somewhere. A great place to do that is before the change to the 4 chord in bar 5. Once you get the hang of that move, on to the next chord. I recommend that you listen to guys who do this stuff to get it in your ears. Robben Ford is an excellent first choice.
