Watch the V IV in D online guitar lesson by Brad Carlton from Guitar Lab: Vertical Soloing

I'll show you how to sprinkle in the blues scale over this V IV progression. The secret is to be comfortable with both approaches: the A blues scale and the A mixolydian mode. I'll also discuss the add 4 and the add #4 arpeggios over the A and G chords in this V IV progression in the key of D. The end of this lesson covers the application of the G Major 7 arpeggio.
