About the I-IV-V progression
The I-IV-V progression uses the three primary chords of the key — nothing else. It's the harmonic foundation of blues, folk, country, and early rock and roll. Learning to switch between these three chords fluently in every key is a fundamental milestone for beginner guitarists.
Playing in the key of E
E major is a staple of rock and blues guitar — think Chuck Berry, Jimi Hendrix, and countless Rolling Stones classics. E, A, and D are open shapes; C#m as the relative minor is a barre chord.
