The generator for its harmonic entropy minimum is the cube root of 8/5.&lt;br /&gt;


It is the chromatic scale of [[Orwell|Orwell temperament]]. The [[harmonic entropy]] minimum for this scale has three [[dark]] generators map to [[8/5]] (~813.6{{c}}), where the generator is ~271.2{{c}}.

9L 4s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 9 large steps and 4 small steps, repeating every octave. 9L 4s is a child scale of 4L 5s, expanding it by 4 tones. Generators that produce this scale range from 923.1 ¢ to 933.3 ¢, or from 266.7 ¢ to 276.9 ¢.

It is the chromatic scale of Orwell temperament. The harmonic entropy minimum for this scale has three dark generators map to 8/5 (~813.6 ¢), where the generator is ~271.2 ¢.

Scale properties

This article uses TAMNAMS conventions for the names of this scale's intervals and scale degrees. The use of 1-indexed ordinal names is reserved for interval regions.
