How to form diatonic chords of A flat minor scale?

A Flat Minor Scale

A♭ – B♭ – C♭ – D♭ – E♭ – F♭ – G♭ – A♭ are the notes of the A flat minor scale.

Diatonic chords are formed by stacking two generic third notes above each scale note.

A Flat Minor Diatonic Chords

These are the seven minor scale diatonic chords that come from the A flat minor scale.

Each diatonic chord is labelled with a roman numeral number.

All natural minor scales follow the same patten:

i,  iiº,  III,  iv,  v,  VI,  VII

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.

First, fourth and fifth chords of a natural minor scale will always be minor. Third, sixth and seventh chords of a natural minor scale will always be major. Second chord of a natural minor scale will always be diminished.

The seven diatonic chords formed from the key of A flat minor are:

i.  A♭ – C♭- E♭ (A♭ minor chord)

iiº.  B♭ – D♭ – F♭ (B♭ diminished chord)

III.  C♭ – E♭ – G♭ (C♭ major chord)

iv.  D♭ – F♭ – A♭ (D♭ minor chord) *Notice that D♭ and C♯ are enharmonic equivalents. C♯ minor chord is used more commonly than D♭ minor chord.

v. E ♭ – G♭ – B♭ (E♭ minor chord)

VI.  F ♭ – A♭ – C♭ (F♭ major chord) *Notice that F♭ and E are enharmonic equivalents. E major chord is used more commonly than F♭major chord.

VII.  G♭ – B♭ – D♭(G♭ major chord)

These are the chords that are diatonic to the A flat minor scale. They are directly related to the A flat minor key and make a harmonic sound for music in the same key.
