How to form diatonic chords of B flat minor scale?

B Flat Minor Scale

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

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

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 the same patten:

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.

First, fourth and fifth chords of a natural minor scale will always be minor. Third, sixth and seventh chords of a natural minor scale will always be major. Second chord of a natural minor scale will always be diminished.

The seven diatonic chords formed from the key of B flat minor are:

i.  B♭ – D♭- F (B♭ minor chord)

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

III.  D♭ – F – A♭ (D♭ major chord)

iv.  E♭- G♭ – B♭ (E♭ minor chord) 

v.  F – A♭ – C (F minor chord)

VI.  G♭- B♭ – D♭ (G♭ major chord) 

VII.  A♭ – C – E♭(A♭ major chord)

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