Chromatic scale Chromatic scale The chromatic scale is a musical scale with twelve pitches, each a semitone above or below its adjacent pitches. As a result, in 12-tone equal temperament (the most common temperament in Western music), the chromatic scale covers all 12 of the available pitches. Thus, there is only one chromatic scale. Moreover, in equal temperament, all the semitones have the same size (100 cents). As a result, the notes of an equal-tempered chromatic scale are equally-spaced. This makes the chromatic scale a nondiatonic scale with no tonic because of the symmetry of its equally-spaced notes. The ascending and descending
Synthetic scale By adding a G to the scale, one would end up with the LydianVII, the fourth degree of the Melodic Minor scale. The pitches of synthetic scales may duplicate pre-existing scales, though their derivation is different and their use is often quite different. Synthetic scale In music, a synthetic scale is a scale that derives from a traditional diatonic major scale by altering of one degree by a semitone in either direction. Composer Ferruccio Busoni originally explored these scales in his "A New Esthetic of Music" and their number and variety were later clarified by J. Murray Barbour, who also
