11L 2s

11L 2s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 11 large steps and 2 small steps, repeating every octave. 11L 2s is a grandchild scale of 2L 7s, expanding it by 4 tones. Generators that produce this scale range from 646.2 ¢ to 654.5 ¢, or from 545.5 ¢ to 553.8 ¢. This scale is most notable for being used by Ivan Wyschnegradsky, bearing the name diatonicized chromatic scale. Eliora has proposed the name hendecoid for its strong relationship to the number 11, as it's an 11+-limit scale and has generators that are close to 11/8. Frostburn has proposed the name p-enhar balzano, as a grandchild scale of 2L 7s.

From a regular temperament theory perspective, is notable for correponding to the mega chromatic scale of Heinz temperament. Its generator of 5\11 to 6\13 hits so close to 11/8 as to be able to be called nothing but that interval, making it an 11+-limit scale. If just 11/8 is used as generator, the step ratio is around 1.509.

Scale tree

Template: Scale tree is deprecated. Please use Template: MOS tuning spectrum instead. Details: Use of a single Comments parameter has become unmaintainable. Existing scale trees should be migrated to the new template, where comments are entered using a step ratio p/q as a parameter: {{MOS tuning spectrum | 3/2 = Example comment | 4/3 = Another example comment }} The parameters tuning and depth have been replaced with Scale Signature and Depth, respectively.
