How the chords work

Written in Roman numerals, this progression is I – ♭III – ♭VII – IV — in C major that is C – Eb – Bb – F. 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 major chord borrowed from the minor key (the relative major in a minor key).
• ♭VII — a major chord a whole step below home, borrowed from the minor key — classic rock swagger.
• IV — a bright, open chord a fourth above home — the "amen" chord.

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 A 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 A major pentatonic or A major scale or A Mixolydian — 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.
