In music theory, this wheel of fourths or fifths is a visual representation of the relationships among the 12 tones of the chromatic scale, their corresponding key signatures, and the associated major and minor keys. More specifically, it is a representation in pitch class space. In more mundane terms, an interior and an exterior, where the circle is the former and the latter is called a disk. It’s a closed curve which divides the plane into two regions: a simple shape of Euclidean geometry where all points in a plane are at a given length from a specific location or the centre. The distance between any of these is called the radius. It can also be defined as the locus which is equidistant to the edge. In strict technical usage, this ring may be interchanged to refer to either the boundary of the figure, or to the whole including its interior. This presentation of The 3D RadioActivity will focus on these specific objects in several ways. We have gone around earlier, so this time the plan is to spin at least a dozen tracks, all revolving round this figure, as we play our own particular cyclical interpretations.
