Key signature sometimes called "standard key signatures". Other scales are written either with a standard key signature and use accidental as required, or with a nonstandard key signature. Examples of the latter include the E (right hand), and F and G (left hand) used for the E diminished (E octatonic) scale in Bartók's "Crossed Hands" (no. 99, vol. 4, "Mikrokosmos"), or the B, E and F used for the D Phrygian dominant scale in Frederic Rzewski's "God to a Hungry Child".

C-flat major C-flat major C major (or the key of C) is a major scale based on C, consisting of the pitches C, D, E, F, G, A, and B. Its key signature has seven flats. The direct enharmonic equivalent of C major is B major, a key signature with five sharps. The C major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> C major is the only major or minor key, other than theoretical keys, which has "flat" or "sharp" in its name, but whose tonic note is the enharmonic equivalent of a natural note (a white key
