A horogram is a diagram that visualizes the [[interval]] pattern for a [[scale]] based on a repeated [[Generator|generating]] interval. This is useful for visualizing the step pattern for [[MOS|moment-of-symmetry scales]] and other similar scales. | |||

The most familiar form of the horogram is based on Wilson's work. Here, the size of the generating intervals are represented as angles, and successive circles radiating from the center represent increasingly chromatic child scales. | The most familiar form of the horogram is based on Wilson's work. Here, the size of the generating intervals are represented as angles, and successive circles radiating from the center represent increasingly chromatic (fine) child scales. | ||
