\naturalThe natural sign, represented by \natural, is a musical notation symbol used to cancel a previous accidental and restore the note to its original pitch. In mathematics, it is sometimes used to denote natural numbers, although this usage is less common.
In musical notation, this indicates that the note C is natural, canceling any previous sharps or flats.
C\naturalIn mathematics, the set of natural numbers is sometimes denoted by \mathbb{N}, although the \natural symbol itself is not typically used for this purpose.
\mathbb{N} = \{0, 1, 2, 3, \ldots\}In a musical context, this indicates that the melody begins with a B natural note.
