Natural

A natural cancels a sharp or flat, returning the note to its plain pitch. A natural before B means B, not B flat or B sharp.

How to read it

The natural undoes a sharp or flat from earlier in the same measure, or one in the key signature. Where a key changes, naturals also cancel the old key signature. Some older writers call it the cancel.

Where the sign comes from

Two stories are told. Gehrkens (1914) derives it from the German letter H, which is what Germans call B natural. Stainer and Barrett’s dictionary (1898) finds the earliest known use of the sign in Bonaffino’s Madrigali Concertati of 1623.

Look-alikes

The Sharp has two full vertical strokes crossed by two bars; the natural’s strokes are offset, one reaching up and one down, and meet the bars to form a box.
