The natural sign is in the notation applied characters. It makes changes in pitch (increase or decrease), by pre- or accidentals (including accidents) are required, the clock reversed. The character is written either on a line or a space on the staff and refers to the note on that pitch. If the designated tone is on an auxiliary line , the natural sign is placed in front of the auxiliary line.

For example, a cis '' , which was reached by a cross in front of the note with the pitch c '' , is returned to a c '' by a natural sign in front of the next note in the same position :

On the other hand, a note lowered by a to the ′ ′ becomes a d ′ ′ again after dissolution :

The natural symbol also completely removes double accidentals ( double crosses or double b ).

Here z. B. a gisis' (double cross in front of g ' ) resolved to g' :

and here an ases ′ (double B before a ′ ) to the a ′ :

Since an accidental always calculates from the respective root note , an accidental is always implicitly preceded by a natural hyphen without having to be noted. For example, the note is gis by a subsequent for ges lowered without it before a resolution to g needs. In older printed music, the natural sign is occasionally also notated in such a context, but this notation is now considered out of date.

In addition to being used as an accidentals , in which the natural mark is placed directly in front of a note and is valid until the end of the measure, the natural mark can also be used to change the prefix of a piece of music. In this case a natural sign is written for each accidental, and then after a double barline the accidental of the new key .

Natural sign is also used in figuring the basso ago. There it states that the alteration of the third of the chord to be played should be ignored.

history

In the older chorale notation , only two accidentals emerged from the 10th century, which always related to the root note B : the b rotundum ("round B") or also b molle ("soft B") denoted the lower tone variant, the b quadratum ("square B") or also b durum ("hard B") is the higher. From the b quadratum both the cross and the cancellation sign developed . The foreign-language terms comfortably (Italian) and bécarre (French) for the natural sign are derived from the designation b quadratum .
