Fig.2. This five-string Open G riff includes slid double stops for a pretty country effect. The phrase opens with these double stops and a classic G major pentatonic fill that Keith often employs in this tuning. The rhythm pattern in bars 2 and 3 is a variation on the 5-to-6 comping figure of rock and roll and applies the advantages of the open G tuning to generate larger chords than are normally played.
