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
In scale and containing notes between them, as in the "miyako-bushi" scale used in "koto" and "shamisen" music and whose pitches are equivalent to the "in" scale: In Indian classical music, Gunkali (Hindustani) and Karnataka Shuddha Saveri (Carnatic) are nearly identical to the pentatonic "in" scale, highlighting the shared past of their origins. Some rare examples of ancient genres of Andean music (e.g. k'antu) use a scale similar to the "in" scale combined with melody leading with a parallel fifths and fourths. For example listen to "Machulas Kantu" by Bolivia Manta folk group ("Wiñayataqui", 1981). In scale The in" scale (also known
