How to form diatonic chords of A sharp minor scale?

A Sharp Minor Scale

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

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

A Sharp Minor Diatonic Chords

These are the seven minor scale diatonic chords that come from the A sharp 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 A sharp minor are:

i.  A♯ – C♯ – E♯ (A Sharp minor chord)

iiº.  B♯ – D♯ – F♯ (B Sharp diminished chord) * Notice that B♯ and C are enharmonic equivalents. C diminished chord is the same as B♯ diminished chord. C diminished chord is more commonly used than B♯ diminished chord.

III.  C♯ – E♯ – G♯ (C Sharp major chord)

iv.  D♯ – F♯ – A♯ (D Sharp minor chord)

v. E♯ – G♯ – B♯ (E Sharp minor chord) *Notice that E♯ and F are enharmonic equivalents. F minor chord is the same as E♯ minor chord. F minor chord is used more often than E♯ minor chord.

VI.  F♯ – A♯ – C♯ (F Sharp major chord)

VII.  G♯ – B♯ – D♯ (G Sharp major chord) * G♯ and A♭ are enharmonic equivalents.  A Flat major chord is the same as G♯ major chord, and used more commonly than G♯ major chord.

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