How to form diatonic chords of E flat major scale?

E Flat Major Scale

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

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

E Flat Major Diatonic Chords

These are the seven major scale diatonic chords that come from the E 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 E flat major are:

I.  E♭ – G – B♭ (E Flat major chord)

ii.  F – A♭ – C (F minor chord)

iii.  G – B♭ – D (G minor chord)

IV.  A♭ – C – E♭ (A Flat major chord)

V. B♭ – D – F (B Flat major chord)

vi.  C – E♭ – G (C minor chord)

viiº.  D – F – A♭ (D diminished chord)

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