Theory behind the chord
Minor chords sound darker than major ones because the third is lowered by a semitone. They carry the melancholic colour in most songs and pair naturally with their relative major. On A#m this structure sits on the root A#, so the degrees 1 – ♭3 – 5 map onto A#, C# and F. A#m is the vi chord in the key of C# major, the ii chord in G# major and the iii chord in F# major. Its relative major is C#. It is often heard in the A#m – F# – C# – G# progression.
