Watch the Blues Scale - 12th Fret online guitar lesson by Robbie Calvo from 25 Blues Turnarounds
Blues Turnaround 7 is played at the 12th fret E blues scale. I'm implying the G# note by slightly bending the G note. I'm raking the top 2 strings on the intro of this turnaround too. Note that there's a double-stop 3rd element to this phrase as well that I'm attacking with a rake and playing with my first finger on the G and B strings, 12th fret. Bend these notes slightly too, giving the line a bit of swagger and sass.
