11L 15s
11L 4s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 11 large steps and 4 small steps, repeating every octave. 11L 4s is a grandchild scale of 4L 3s, expanding it by 8 tones. Generators that produce this scale range from 320¢ to 327.3¢, or from 872.7¢ to 880¢.
The bright generator represents a minor third slightly sharp of 6/5 (315.6¢). At its harmonic entropy minimum, the octave-reduced 7th harmonic (about 968¢) equals 3 of these generators.
