Natural (music)

[1]The natural symbol can be used as an accidental to cancel sharps or flats on an individual note.

A note marked with a natural sign can be changed to a flat or sharp by simply applying the new accidental.

A natural sign (♮) cancels a flat or sharp from a previous note or key signature.

Sometimes these cancelling naturals at a key change are omitted, but they must be used if the new key has no flats or sharps.In the music notation program Lilypond, naturals are used at a key signature change to cancel a flat or sharp from the previous key signature, but are not shown when the flat or sharp changes to double flat or double sharp.

Similarly, a simple ♭ or ♯ without a natural sign can be used to indicate that a double flat or double sharp has been changed to a single flat or sharp, but older notation may use ♮♭, ♭♮, ♮♯, or ♯♮ instead.
