How to form diatonic chords of D major scale?

D Major Scale

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

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

D Major Diatonic Chords

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

I.  D – F♯ – A (D major chord)

ii.  E – G – B (E minor chord)

iii.  F♯ – A – C♯ (F Sharp minor chord)

IV.  G – B – D (G major chord)

V. A – C♯ – E (A major chord)

vi.  B – D – F♯ (B minor chord)

viiº.  C♯ – E – G (C Sharp diminished chord)

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