The word "chromatic" comes from the Greek word chroma meaning "color." The chromatic scale consists of 12 notes each a half step apart. It is from the chromatic scale that every other scale or chord in most Western music is derived. On the piano/keyboard when you play all the black and white keys of an octave in an ascending or descending order you are playing a chromatic scale.
