Staff Notation
Accidentals
Once an accidental has appeared in a bar, it remains in force until the end of the bar.
If a note with an accidental is tied over a bar line, the accidental is not written again.
Unlike sharps and flats in a key signature, an accidental applies only to the line or space on which it is written.
