What Are Accidentals?

An accidental is a symbol that turns a note into a sharp, a flat, or a natural:

  • Sharp (♯): Makes a note higher in pitch by a half step.

  • Flat (♭): Makes a note lower in pitch by a half step.

  • Natural (♮): Returns a note to its original pitch after having been sharpened or flattened. Naturals also cancel out sharps or flats implied by a key signature.


Double-sharps (x) and double-flats (♭♭) occur in certain chords and scales. Double-naturals (♮♮) cancel out a double-accidental in traditional sheet music, but a single natural sign may now be used.
