The signature of F♯ major is six sharps, F♯, C♯, G♯, D♯, A♯ and E♯. A♯ is one of them, which is why you never see a sharp written next to the note — the signature at the start of the staff already said it.

Spelled from the tonic, the F♯ major scale runs F♯, G♯, A♯, B, C♯, D♯, E♯ — one of each letter, each carrying whatever the signature gives it. The staff above draws the F♯ major signature and the note A♯ inside it — exactly as you would meet it in a piece written in this key.

  • A is A♯ — the letter on this page
  • B is B (natural — the signature leaves it alone)
