natural

A natural sign (♮) cancels a previous sharp or flat, returning a note to its unaltered pitch. If a key signature includes F♯, a natural sign before an F in the music temporarily restores it to F♮ for the remainder of that measure. Naturals are essential for clarity in music notation. They appear as courtesy or cautionary accidentals — reminders that a previously altered note has returned to its natural state, even when this is technically already implied by the bar line. In educational contexts, understanding the difference between sharps, flats, and naturals is one of the first steps in learning to read music.
