Hi GMC! This lesson is about using vibratos and phrasing in the blues style. The chord progression is a typical 12 bar blues in Eb. The vibratos and phrasing are based on Stevie Ray Vaughan's style.
Some tips while playing a blues progression: try to be just a bit behind the metronome to achieve a really mean bluesy feel. Also use "micro bending" whenever you can. It can be achieved by hitting a note, and just before you releace it, bend it just a little. Mind your vibratos and make them even as much as you can.
