How the chords work
Written in Roman numerals, this progression is I – iii – IV – V — in C major that is C – Em – F – G. Each numeral is a step of the scale; upper case is a major chord, lower case minor.
- I — the home chord — the progression feels finished when it lands here.
- iii — a gentle minor chord that shares two notes with I.
- IV — a bright, open chord a fourth above home — the "amen" chord.
- V — the tension chord that wants to resolve home.

Practice ideas
- Beginners: play one strum per chord and say the chord names out loud, then two strums, then a steady down-down-up-up-down-up pattern.
- Change keys with a capo: keep the G major shapes and move a capo up — the capo calculator shows which fret gives the key you want.
- Solo over it: loop it in the Looper and improvise with the G major pentatonic or G major scale — the scale pages show every position and play a backing track.
- Train your ear: the progression ear trainer mixes this with similar progressions until you can tell them apart.
