A C chromatic scale is a musical scale that consists of all twelve pitches within the octave. It is named "chromatic" because it includes both the white and black keys on a piano keyboard. The C chromatic scale starts and ends on the note C, and it includes all the half steps (semitones) within the octave, including both the natural and altered pitches. The sequence of notes in a C chromatic scale is as follows: C, C#, D, D#, E, F, F#, G, G#, A, A#, B, C.
