The I-IV two-chord vamp alternates between tonic and subdominant. It's a favorite of reggae, folk, and any genre where the harmony steps back to let the groove drive.
Playing in the key of G
G major is one of the easiest keys on guitar. Its primary chords — G, C, and D — are all open first-position shapes, and the relative minor (Em) is one of the simplest grips on the instrument. A great key to spend time in as a beginner.
