Natural (music) (Redirected from Natural sign)

In music theory, a natural (♮) is an accidental which cancels previous key signatures or accidentals and represents the unaltered pitch of a note.

Examples

It can be used as key signature or accidental. An example of an A note with an accidental in place is shown below.

 {
\override Score.TimeSignature #'stencil = ##f
\relative c'' {
   \time 4/4 a!1
} }

A note is natural when it is neither lowered nor raised by other key signatures or accidentals. Natural notes are the notes A, B, C, D, E, F, and G represented by the white keys on the keyboard of a piano or organ. On a modern concert harp, the middle position of the seven pedals that alter the tuning of the strings gives the natural pitch for each string.

The scale of A minor or C major is sometimes regarded as the central, natural or basic minor scale or major scale because all of its notes are natural notes, whereas every other major scale in the circle of fifths has at least one of other accidental signs in it.

The notes F, C, E, B, and most notes inflected by double-flats and double-sharps correspond in pitch with natural notes; however, they are not regarded as natural notes but rather as enharmonic equivalents of them and are just as much chromatically inflected notes as most sharped and flatted notes that are represented by black notes on a keyboard.

The natural sign is derived from a square b used to denote B in medieval music (in contrast with the round b denoting B, which became the flat symbol). The Unicode character MUSIC NATURAL SIGN '♮' (U+266E) should display as a natural sign. Its HTML entity is ♮.

Notation

In musical notation, a natural sign () is a sign used to cancel a flat or sharp from either a preceding note or the key signature. (Ex. A flat Major -> F Major)

{ \time 1/4 \override Score.TimeSignature #'stencil = ##f { \clef treble \key aes \major s16 ^\markup "" \bar "||" \key f \major s16 ^\markup ""}}
{ \time 1/4 \override Score.TimeSignature #'stencil = ##f { \clef treble \key aes \major s16 ^\markup "" \bar "||" \set Staff.KeyCancellation = ##f \set Staff.keyAlterations = #`((6 . ,FLAT)(2 . ,NATURAL)(5 . ,NATURAL)(1 . ,NATURAL)) s16 ^\markup ""}}

But, naturals are assumed (by default) in key signatures and mentioned only in key signature changes.

However, in some cases, as in John Foulds' A World Requiem, the naturals are sometimes omitted in the position of the canceled flats or sharps in the previous key signature. It seems to be aimed at reducing writing time and improving readability.

When used as an accidental, it is written to the left of the note head.

 {
\override Score.TimeSignature #'stencil = ##f
\relative c'' {
   \clef G \time 4/4 b!1
} }

When used as an accidental, it is applied to the note after the natural sign in the same octave in the same bar.

To cancel the natural used as an accidental in the same octave within the same bar, use other accidentals such as a flat (♭) or a sharp (♯).

Double natural

A double natural is a symbol that has two naturals (♮♮).

In a case where one needs to cancel both flats or sharps of a double flat or double sharp, it is acceptable to write a single natural (♮) in modern notational practice. In older practice, two naturals () can be written. (It's a 'double natural' sign.)

 {
\override Score.TimeSignature #'stencil = ##f
\relative c'' {
  \clef G \time 4/4 beses2_\markup "Older Practice" \tweak Accidental.restore-first ##t b bisis \tweak Accidental.restore-first ##t b beses_\markup "Modern Practice" b bisis b
} }

Similarly, to cancel one flat or sharp from a double flat or double sharp, the traditional convention is to use (♮♭ or ♭♮) or (♮♯ or ♯♮) instead of ♭ or ♯, respectively, but the naturals are generally omitted in modern notational practice: It is acceptable to use ♭ or ♯.

 {
\override Score.TimeSignature #'stencil = ##f
\relative c'' {
  \clef G \time 4/4 beses2_\markup "Older Practice" bes bisis2 bis \accidentalStyle modern beses_\markup "Modern Practice" bes bisis2 bis
} }
  • Theoretically, the same principle could be considered when canceling the symbol of a triple sign(Triple flat/Triple sharp) or beyond.
  • When changing a flat to a sharp or visa versa, the combined symbols ♮♭ or ♮♯ can be used.
  • In John Stump's Prelude and the Last Hope, a double natural (♮♮) was used in the position of the canceled double flats in the key signature.
