I am making some progress on clawhammer. I am starting to get the E string. I was trying to use too much force. I was trying to force my way through the E string and not doing much beside muting and bending the string. But by glancing off the string I get the note.
Aside from that I was just dinking around with some blues progressions in minor keys as well as playing some Eb blues in primarily the mixolydian mode.
I finally figured out why there were only five shapes whereas there are 6 notes in the blues scale. The 5 shapes refer to the pentatonic scale which doesn't have the blue note.
