12L 6s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 12 large steps and 6 small steps, with a period of 2 large steps and 1 small step that repeats every 200.0 ¢, or 6 times every octave. 12L 6s is a child scale of 6L 6s, expanding it by 6 tones. Generators that produce this scale range from 66.7 ¢ to 100 ¢, or from 100 ¢ to 133.3 ¢. Scales of the true MOS form, where every period is the same, are proper because there is only one small step per period.

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.
