This MOS, also called the '''Happy tridecatonic scale''', has its first [[harmonic entropy]] minimum at 1/[[14edo]]-3/[[40edo]], where 3:2 is +8 [[generator]]s (giving [[Octacot]]). However, the absolute harmonic entropy minimum is [[Nautilus]] (3:2=-6 generators), and that is not complete until 14 tones.

1L 12s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 1 large step and 12 small steps, repeating every octave. 1L 12s is a great-grandchild scale of 1L 9s, expanding it by 3 tones. Generators that produce this scale range from 1107.7 ¢ to 1200 ¢, or from 0 ¢ to 92.3 ¢.

This MOS, also called the Happy tridecatonic scale, has its first harmonic entropy minimum at 1/14edo-3/40edo, where 3:2 is +8 generators (giving Octacot). However, the absolute harmonic entropy minimum is Nautilus (3:2 ← −6 generators), and that is not complete until 14 tones.

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.
Template:MOS data is deprecated.

Details: Please use the following templates individually: MOS intervals, MOS genchain, and MOS mode degrees
