Watch the Double - Stop Turnarounds online guitar lesson by Robbie Calvo from 25 Blues Turnarounds
Blues Turnaround 18 is a series of ascending major and minor double-stop 6th's. This is such a cool line - notice that the chord tone double stops are connected by chromatic double stops. Don't land and rest on the chromatics, as they won't sound good. Play through them however, and it connects the chord tones perfectly. Watch how I finger the two different shapes of major and minor double-stops and make this constant every time you play these intervals.
