How the chords work
Written in Roman numerals, this progression is I – ♭VI – I – ♭III — in C major that is C – Ab – C – Eb. 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.
- ♭VI — a major chord borrowed from the minor key: epic and dramatic.
- ♭III — a major chord borrowed from the minor key (the relative major in a minor key).

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 E 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 E major pentatonic or E 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.
