Is A sharp in B major?

In B major, A is A♯: the key signature puts a sharp on every A, in every octave, for as long as that signature stands.

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

Every letter in B major

B major has five sharps, F♯, C♯, G♯, D♯ and A♯. That fixes what each of the seven letters is called in this key:

  • C is C♯
  • D is D♯
  • E is E (natural — the signature leaves it alone)
  • F is F♯
  • G is G♯
  • A is A♯ — the letter on this page
  • B is B (natural — the signature leaves it alone)

B major shares its signature with its relative G♯ minor — the same sharps or flats, so A is A♯ there too.

B major and C♭ major are the same key on the keyboard, written two different ways — so they answer this question differently: A is A♯ in B major, and A♭ in C♭ major.
