A sign added to a note to change the pitch. There are three accidentals used in Music; sharp, flat and natural.
- A sharp raises a note by one semitone.
- A flat lowers a note by one semitone.
- A natural cancels all accidentals and returns a note to its normal pitch.
Accidentals last until the following barline where they are cancelled and will not affect any further notes. Notice that the accidental is placed before the note to be affected on exactly the same line (or space).
- Semitone (N5 & N5 Tech)
