Two slanted horizontal bars crossed by two vertical strokes, raising a note by a semitone.
Also known as: Two crossed lines music
Sometimes confused with: Hash music symbol
♯ raises a note by a semitone. It is a different character from the number sign #, and the two are substituted for each other constantly — the sharp's horizontals slant upward and its verticals are upright, where the number sign is the other way round.
