Watch the Blues Scale - 7th Fret online guitar lesson by Robbie Calvo from 25 Blues Turnarounds
Blues Turnaround 4 is played at the 7th fret using the E blues scale. You'll notice that I'm working my way through each pattern of the blues scale, so you may even want to think in terms like this when playing too: moving through the patterns. Note that I'm blues bending the A note up to Bb (the b5) and I don't actually reach the pitch of Bb, so think of this as implying the note, not actually achieving it. This is a nice lick that descends through the blues scale from high to low. Play slowly at first and build up to speed.
