B Flat Minor Diatonic Chords
These are the seven minor scale diatonic chords that come from the B flat minor scale.

Each diatonic chord is labelled with a roman numeral number.

All natural minor scales follow this pattern of chord quality:
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.
1, 4 and 5 chords in natural minor will always be minor chords. 3, 6 and 7 chords in natural minor scale will always be major chords. 2 chord in natural minor scale will always be diminished chord. A different pattern applies to harmonic minor: i iiº III+ iv V VI viiº and melodic minor: i ii III+ IV V viº viiº
