Sharp (music)

The cross ♯ denotes the increase in the music of a Stammtons by a semitone. On the note names of the altered clay -is the ending is appended. This suffix is an abbreviation of the Greek word diesis, the designated one semitone in antiquity. The character is written as a double cross with two vertical parallel longitudinal bars and two oblique upward dashes. The character is written either on a line or space of the staff, and altered the standing on this pitch tone. If the tone to be increased on an auxiliary line, so the cross is placed in front of the guide.

The symbol is used in two ways:

• As accidentals, it is right in front of a particular note; it is only in that cycle in which it is listed, and only for the designated octave
• As a sign it is immediately after the clef and applies either to the end of the piece, or until it is resolved by other signs; it also applies to all octave ranges

History

In the older chant notation formed from the 10th century, initially only two accidentals out that always referred to the Stammton B: the b rotundum ( "round B") or b molle called the lower Tonvariante, the b quadratum or b durum ( " square B") higher. From the b quadratum both the cross and the resolution characters developed.

Representation in computer systems

In the international character encoding Unicode system is the cross ♯ U 266 F to position musical sharp sign ).

The # sign (U 0023 number sign, pound sign ) is a separate character and not identical with the cross of musical notation. However, it is often used as a substitute representation for the cross.

Varia

Several programming languages, most of which were designed for. NET platform, carry the cross in their names. Examples:

• C # (pronounced C sharp)
• F # (pronounced F sharp)
• J # (pronounced J sharp)

However, since the increase in characters can be directly entered on any standard keyboard, using practical purposes, most of the double cross.
