Watch the Mixolydian b6 Lick online guitar lesson by Tom Dempsey from Jazz Scales Handbook
Let's look at a musical idea out of the sound of the Mixolydian b6 scale. Here I'll show you a four bar lick from the G Mixolydian b6 scale that is played over a G7b13 chord with a swing groove. In playing this idea, you'll notice that this scale really highlights that b13 tension on the dominant seventh chord. It's like a little spice on your dominant chord. Sometimes just having that little bit of tension is just enough to add interest to you line.
