B natural/diatonic minor often borrows the 7th note from B harmonic minor; it’s just one semitone higher but creates and resolves tension far better than its diatonic counterpart.
This raises B minor’s A to A#, which affects B minor’s III, v, & VII chords:
| III+ | V | vii° |
|---|---|---|
| Daug | F# | A#dim |
| D augmented | F sharp major | A sharp diminished |
| D - F# - A# | F# - A# - C# | A# - C# - E |
