12 bar blues by D.Rubin

[Triple-o]

Shuffle in E p.21.
When I got  to the 5 chord I found it to be challenging. Some might find it impossible.Thanks to Jimmy Reed I no longer feel the need to make this uncomfortable stretch. I just look at the chord tones B F# D#  and the parallel Em/E major pentatonic scales and play whatever I want in that measure.You could also change  that B to B7  and use the open A string as the flat 7th (Jimmy did that) which opens up other possibilities.The last measure or turnaround looks like a  modulation to the key of F.

The author (Rubin) states “historical research” points to the boogie woogie on guitar before the piano. Other  “historical research” points to the piano and the creation of the “cut boogie”  might also point to the piano. So,take your pick.😎
