Remarks

An accidental may raise a pitch by one or two semitones or it may cancel a previous accidental or part of a key signature. This element provides an alternative to the accid and accid.ges attributes on the note element. The element may be used when specific display info, such as size or color, needs to be recorded for the accidental or when multiple accidentals occur on a single note. The func attribute can be used to differentiate between the accidental’s functions, such as 'cautionary' or 'editorial'.
