This MOS is the simplest that has a [[tritone]] as the only possible size of a [[generator]], since the smallest size for a tritone is defined to be 7\[[15edo]] (560{{c}}). Since its generator is a tritone, its [[harmonic entropy]] minimum is where the generator is 7/5.

2L 13s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 2 large steps and 13 small steps, repeating every octave. 2L 13s is a great-grandchild scale of 2L 7s, expanding it by 6 tones. Generators that produce this scale range from 560 ¢ to 600 ¢, or from 600 ¢ to 640 ¢.

This MOS is the simplest that has a tritone as the only possible size of a generator, since the smallest size for a tritone is defined to be 7\15edo (560 ¢). Since its generator is a tritone, its harmonic entropy minimum is where the generator is 7/5.

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.
