The sharps or flats needed to produce a diatonic scale in diatonic or tonal music can be shown as a key signature at the beginning of a section of music instead of showing accidentals on individual notes. While the key of a piece generally corresponds to the notated key signature, it may not in some cases, such as in pre-Baroque music, which ...
In most cases, a sharp raises the pitch of a note one semitone while a flat lowers it one semitone. A natural is used to cancel the effect of a flat or sharp. This system of accidentals operates in conjunction with the key signature, whose effect continues throughout an entire piece, or until another key signature is indicated.
Key signatures indicate which notes are to be played as sharps or flats in the music that follows, showing up to seven sharps or flats. Notes that are shown as sharp or flat in a key signature will be played that way in every octave—e.g., a key signature with a B ♭ indicates that every B is played as a B ♭. A key signature indicates the ...
In music, flat means lower in pitch. It may either be used generically, meaning any lowering of pitch, or refer to a particular size: lowering pitch by a chromatic semitone. A flat is the opposite of a sharp (♯) which raises pitch by the same amount that a flat lowers it. ♭
In music, 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.
A key signature with no sharps or flats generally indicates A minor or C major, using all natural notes with no sharps or flats. The natural sign is derived from a square b used to denote B ♮ in medieval music (in contrast with the round b denoting B ♭, which became the flat symbol).
When a musical key or key signature is referred to in a language other than English, that language may use the usual notation used in English (namely the letters A to G, along with translations of the words sharp, flat, major and minor in that language): languages which use the English system include Irish, Welsh, Hindi, Japanese (based on katakana in iroha order), Korean (based on hangul in ...
