Key signature may consist of one or more sharps combined with one or more flats (such as a signature containing both F and B).

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
