Chromatic circle "discrete" structure, and there is no obvious way to assign pitch classes to each of its points. A pitch constellation is a graphical representation of pitches used to describe musical scales, modes, chords or other groupings of pitches within an octave range. It consists of a circle with markings along the circumference or lines from the center which indicate pitches. Most pitch constellations use of a subset of pitches chosen from the twelve pitch chromatic scale. In this case the points on the circle are spaced like the twelve hour markings on an analog clock where each tick mark represents
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
