B Minor Family Chords

The Bm family chords are derived from the B minor scale, which consists of the following notes:

B Natural Minor Scale
B, C#, D, E, F#, G, A, B

From this scale, the family chords (diatonic chords) are built by stacking thirds on each degree of the scale. 

The chord qualities follow the pattern of the minor scale:
minor - diminished - major - minor - minor - major - major.


Chords in the B Minor Family:
B Minor (i)
Notes: B, D, F#
The tonic chord and home base of the key, establishing the minor tonality.

C# Diminished (ii°)
Notes: C#, E, G
A tense chord, often used as a passing chord.

D Major (III)
Notes: D, F#, A
A major chord, adding brightness and relief.

E Minor (iv)
Notes: E, G, B
A minor chord contributing to the somber, emotional tone.

F# Minor (v)

G Major (VI)
Notes: G, B, D
The relative major chord, providing a contrasting brightness.

A Major (VII)
