Sharp (music)

In music, in English sharp – eqv. dièse (from French) or diesis (from Greek δίεσις)[a] – means higher in pitch. The sharp symbol, ♯, indicates that the note to which the symbol is applied is played one semitone higher. The opposite of sharp is flat, indicating a lowering of pitch. The ♯ symbol derives from a square form of the letter b (see History of notation of accidentals for more information).

For the use of the sharp sign in mathematics, see Musical isomorphism. For the use of the sharp sign in computational complexity theory, see ♯P.

Shape[edit]

The sharp symbol (♯) resembles the number (hash) sign (#), in that both have two intersecting sets of parallel double lines. While the number sign may have a pair of horizontal lines, the sharp sign has a pair of slanted lines that rise from left to right instead, to avoid obscuring the staff lines. The other set of parallel lines are vertical in the sharp sign, while the number sign (#) may have slanted lines instead. It is also etymologically independent from the number sign.


Likewise, while the double-sharp sign double sharp resembles a bold-face lower-case x it needs to be typographically distinct.

In Unicode, assigned sharp signs are as follows:

Historically, lowering a to a single sharp could be notated using a natural and sharp sign (♮♯) or vice-versa (♯♮) instead of the conventional sharp sign (♯), but the natural sign is often omitted in modern notation. The similar principle of the natural sign notation can apply when canceling a triple sharp or beyond.[4] The combination ♮♯[5] can be also written when changing a flat to a sharp.[6]
