Key Signature
A chord has no key signature of its own, but the A♯ Minor is the tonic (i) chord of A# Minor, which shares the signature of its relative major, C# Major — 7 sharps (F♯, C♯, G♯, D♯, A♯, E♯, B♯).
Order of sharps
Sharps are added to a key signature in a fixed order. Each new sharp key adds the next sharp on the list.
