In music, sharp, dièse (from French), or diesis (from Greek)[1] means higher in pitch and the sharp symbol raises a note by a half tone.[2] Intonation may be flat, sharp, or both, successively or simultaneously. More specifically, in musical notation, sharp means "higher in pitch by a semitone (half step)," and has an associated symbol (♯), which may be found in key signatures or as an accidental, as may flats.
Under twelve-tone equal temperament, B sharp, for instance, sounds the same as, or is enharmonically equivalent to, C natural, and E sharp is enharmonically equivalent to F natural. In other tuning systems, such enharmonic equivalences in general do not exist. To allow extended just intonation, composer Ben Johnston uses a sharp to indicate a note is raised 70.6 cents (ratio 25:24), or a flat to indicate a note is lowered 70.6 cents.[3]
In tuning, sharp can also mean "slightly higher in pitch" (by some unspecified amount). If two simultaneous notes are slightly out of tune, the higher-pitched one (assuming the lower one is properly pitched) is said to be sharp with respect to the other. Furthermore, the verb sharpen means "raise the frequency of a note, typically by a small musical interval".
Quarter tone between C and C  (half sharp), 50 cents.  Play (help·info)
Half-tone between C and C ♯(sharp), 100 cents. Play (help·info)
Double sharps also exist; these are denoted by the symbol  and raise a note by two semitones, or one whole tone. Less often (in for instance microtonal music notation) one will encounter half, or three-quarter, Play (help·info) or otherwise modified, sharps. A half sharp indicates the use of quarter tones, and may be marked with various symbols including . Play (help·info)
Although very uncommon and used only in modern classical music, a triple sharp (♯) can sometimes be found. This raises a note by three semitones.
[edit] Correctly drawing and printing the sharp sign
C ♯-major/A ♯-minor key signature.
The sharp symbol (♯) may be confused with the number (hash or pound) sign (#). Both signs have two sets of parallel double-lines. However, a correctly drawn sharp sign must have two slanted parallel lines which rise from left to right, to avoid being obscured by the staff lines. The number sign, in contrast, has two compulsory horizontal strokes in this place. In addition, while the sharp also always has two perfectly vertical lines, the number sign (#) may or may not contain perfectly vertical lines (according to typeface and writing style).
Three-quarter tone between C and C  (three-quarter sharp), 150 cents. Play (help·info)
[edit] Unicode
In Unicode, the sharp symbol (♯) is at code point U+266F. Its HTML entity is ♯. The double sharp symbol () is at U+1D12A (so 𝄪). These characters may not display correctly in all fonts.
[edit] Order of sharps
The order of sharps in key signature notation is F♯, C♯, G♯, D♯, A♯, E♯, B♯ ("F"at "C"ats "G"o "D"own "A"lleys "E"ating "B"irds), each extra sharp being added successively in the following sequence of major keys: C→G→D→A→E→B→F♯→C♯. (These are sometimes learned using an acrostic phrase as a mnemonic, for example Father Charles Goes Down And Ends Battle.) Similarly the order of flats is based on the same natural notes in reverse order: B♭, E♭, A♭, D♭, G♭, C♭, F♭ (Battle Ends And Down Goes Charles' Father.), encountered in the following series of major keys: C→F→B♭→E♭→A♭→D♭→G♭→C♭.
In the above progression, key C♯ (with seven sharps) may be more conveniently written as the harmonically equivalent key D♭ (with five flats), and likewise C♭ (with seven flats) written as B (with five sharps). Nonetheless, it is possible to extend the order of sharp keys yet further, through C♯→G♯→D♯→A♯→E♯→B♯→F→C, adding the double-sharped notes F, C, G, D, A, E and finally B, and similarly for the flat keys, but with progressively decreasing convenience and usage.

It was written for piano, of course, because the electric cello had yet to be invented... "I used both of my 5-string electric cellos (one tuned extra high and one extra low) and the acoustic cellos to give this piece a unique feel and a high level of emotion. I used another melody from Beethoven -- try and guess what it is (guess before you scroll down to the credits where it is listed!) It starts at 1:21 and reoccurs throughout the tune. This melody happened spontaneous in the studio and saved the tune from a bad case of writer's block." -Steven Sharp Nelson Credits Music produced by Al van der Beek & Steven Sharp Nelson Written and performed by Steven Sharp Nelson Inspired by Beethoven's "Moonlight Sonata" and the melody from Beethoven's 7th Symphony, 2nd movement (Allegretto) Recorded, mixed & mastered by Al van der Beek at TPG Studios Video produced by Paul ... |  Mack 10 "So Sharp" Music Video ft.

His lament has an edge: “Your little problem's that you're soaked in gin,” he sings, adding, “I'm sick of begging you to take the reins / wish I could chalk it up to growing pains.” It's acerbic in a Costello vein, carrying a bite to match the sharp music.
