Horogram

Todo: expand This page is a work in progress. Feel free to edit as needed.

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.

Horograms are primarily the work of Erv Wilson.

Diagrams

Circular Horogram

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 more chromatic child scales.

Rectangular Horogram

A rectangular version of a horogram conveys the same information as a circular horogram but in a rectangular format.
