    en.wikipedia.org/wiki/Chromatic_scale

    Definition. [] The chromatic scale is a musical scale with twelve pitches, each a semitone, also known as a half-step, above or below its adjacent pitches. As a result, in 12-tone equal temperament (the most common tuning in Western music), the chromatic scale covers all 12 of the available pitches. Thus, there is only one chromatic scale.

[ 2 ] In the quarter-tone scale, also called 24-tone equal ...
