A# minor has 7 ♯ (F#, C#, G#, D#, A#, E#, B#) in its key signature.
The A# minor scale is: A# B# C# D# E# F# G# A#.
The diatonic chords are A#m (i), B#dim (ii°), C# (III), D#m (iv), E#m (v), F# (VI) and G# (VII). The main functions are A#m (tonic), D#m (subdominant) and E#m (dominant).
In harmonic minor the 7th degree is raised (G##); this turns the dominant into the major chord E#.
