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.

I. D♭ – F – A♭ (D Flat major chord)
