Definição e Significado de "natural"

What is a "natural"?

In music, a natural is a symbol that indicates a note should be played without any sharp or flat alteration. It is represented by a square with two vertical and two horizontal lines extending from the corners (♮). The natural sign cancels any previous sharps or flats applied to a note within a piece of music. For example, if a note has been previously sharpened or flattened, placing a natural sign before it will return the note to its original, unaltered pitch. This helps to ensure that the music is played as intended by the composer.
