In music theory, a natural is an accidental which cancels previous accidentals and represents the unaltered pitch of a note.

A note is natural when it is neither flat nor sharp (nor double-flat or double-sharp). Natural notes are the notes A, B, C, D, E, F, and G are represented by the white keys on the keyboard of a piano or organ. On a modern concert harp, the middle position of the seven pedals that alter the tuning of the strings gives the natural pitch for each string.
