How to form diatonic chords of D flat major scale?

D Flat Major Scale

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

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

D Flat Major Diatonic Chords

These are the seven major scale diatonic chords that come from the D flat major scale.

Each major scale diatonic chord is labelled with a roman numeral number, and follows the same 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.

First, fourth and fifth chords of a major scale will always be major chords. Second, third and sixth chords of a major scale will always be minor chords. Seventh chord of a major scale will always be diminished chords.

The seven diatonic chords formed from the key of D flat major are:

I.  D♭ – F – A♭ (D Flat major chord)

ii.  E♭ – G♭ – B♭ (E Flat minor chord)

iii.  F – A♭ – C (F minor chord)

IV.  G♭ – B♭ – D♭ (G Flat major chord)

V. A♭ – C – E♭ (A Flat major chord)

vi.  B♭ – D♭ – F (B Flat minor chord)

viiº.  C – E♭ – G♭ (C diminished chord)

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