A Flat Major Diatonic Chords
These are the seven major scale diatonic chords that come from the A Flat major scale.
Each major scale diatonic chord is labelled with a roman numeral number:
All major scales follow this chord quality pattern:
I, ii, iii, IV, V, vi, viiº
We use uppercase roman numeral numbers to represent major chords, lowercase to represent minor chords, uppercase with a small plus sign to represent augmented chords, and lowercase with a small circle to represent diminished chords. (1, 4 and 5 chords in major scales will always be major chords. 2, 3 and 6 chords will always be minor chords. 7 chord in major scale will always be diminished chord.)
The seven diatonic chords in the A flat major key are:
I. A♭ – C – E♭ (A Flat major chord)
ii. B♭ – D♭ – F (B Flat minor chord)
iii. C – E♭ – G (C minor chord)
IV. D♭ – F – A♭ (D Flat major chord)
V. E♭ – G – B♭ (E Flat major chord)
vi. F – A♭ – C (F minor chord)
viiº. G – B♭ – D♭ (G diminished chord)
These are the chords that harmonize the A flat major scale.
