Quick answers before you play
What do the Roman numerals in I–IV–V mean?
They describe chord positions inside a key. Uppercase numerals usually mean major chords and lowercase numerals usually mean minor chords.
Can I play this progression in another key?
Yes. Keep the same Roman-numeral pattern and choose a new key. The chord names change, but the musical relationship stays the same.
What strumming pattern should a beginner use?
Begin with one down-strum on beat one of every bar. Then use four down-strums before adding down-up movement.
