I vi IV V Chord Progression on Guitar
The I vi IV V progression is a classic four-chord loop with a warm, nostalgic sound. It is excellent for learning how major and minor chords cooperate inside one key.
Do this first
No theory test. No perfect technique required. Follow these three steps and start making music.
C major chords
Choose another key and the chord names update automatically. The Roman-numeral relationship stays the same.
Why this progression works
Stable at I, softer at vi, open at IV and tense at V before the loop resolves.
Practical shortcut
In C major you will play C, Am, F and G. Practise C to Am separately because that efficient change appears everywhere.
Play it without stopping
Strum two beats per chord at first. Once the sequence is memorized, give every chord a full bar and add a simple down down-up up-down-up pattern.

Quick answers before you play
What do the Roman numerals in I–vi–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.
