JP, I know you’ll be able to answer this! I worked really hard on the 12 bar blues segment of your home course, but listening to those great players we’ve mentioned and watching them on You Tube I actually have to say I’ve not heard any of them play a 12 bar blues. They all solo using improv., or are they playing the 12 bar blues and I’m not hearing it?,
Take Sonny Boy II or Little Walter for instance, when they stop singing and play the harmonica it’s improv. and they never seem to play the same riff twice in a song. I listen to Little Walters song “Juke” and possibly the back ground guys might be playing a 12 bar, but Little Walter does not.
