About the I-V progression
The I-V is the simplest possible progression — just the tonic and dominant. It's the foundation of children's songs, folk anthems, and countless early rock and roll grooves.
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.
