After all, the color wheel is an artificail construct having more to do wi= th application (use) than perception of color. That said: The most common (to western musicians anyway) auditory circular function= would be "the circle of fifths".=20 Though this is a set of relationships rather than a quality inherent to "a= sound", it is generally=20 perceptible and is closely related to consonance and dissonance.?=20 There are, historically speaking, many ways to present the circle of fifth= s. eg.? You could generate wide band (c1 c2 c3 c4 c5 c6...) "notes" for each= pitch class? (a b c d e f...) and divide the circle of fifths various ways.=20 - close and simple, by fifths? (c g d a e...) - distant and complex, by tritones ( c fs c fs c fs...) Perhaps you could look at some ways the color wheel is used to determine= color schemes and=20 imagine using the circle of fifths in a like manner.? Pitch being analogou= s perhaps to brightness, and pitch class being analogous to "color".
