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

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.
