For the B minor scale, its key signature is directly related to its relative major, which is D major. The key signature of B minor includes two sharps: F♯ and C♯. The B minor scale itself follows the pattern of steps characteristic of natural minor scales, resulting in the sequence of notes: B, C♯, D, E, F♯, G, A, and back to B.

This scale can be expanded upon through its harmonic and melodic variants:

Harmonic B minor introduces a raised 7th note (A♯) to create a stronger resolution to the tonic (B), resulting in the scale: B, C♯, D, E, F♯, G, A♯, B.
Melodic B minor raises both the 6th (G♯) and 7th (A♯) notes when ascending, and typically reverts to the natural minor form when descending, thus: Ascending – B, C♯, D, E, F♯, G♯, A♯, B; Descending – B, A, G, F♯, E, D, C♯, B.

The guitar chords that emerge from the B minor scale are:
