Accidental (music) Accidental (music) In music, an accidental is a note of a pitch (or pitch class) that is not a member of the scale or mode indicated by the most recently applied key signature. In musical notation, the sharp (), flat (), and natural () symbols, among others, mark such notes—and those symbols are also called accidentals. In the measure (bar) where it appears, an accidental sign raises or lowers the immediately following note (and any repetition of it in the bar) from its normal pitch, overriding sharps or flats in the key signature. A note is usually raised or lowered
Key signature names and translations if those are the systems used locally. For example recent French scores or books may use the English system (this is especially common for chord symbols), but French users would read out that notation according to the Fixed Do system. Similarly a Dutch musician may refer to a written F orally as Fis. This article is concerned with written usage. To form a key designation, locate the note name in the pitch translation table and add the major/minor qualifier from the lower table as needed. Note that the 'major' alteration is usually superfluous, as a key description missing an alteration
