10L 9s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 10 large steps and 9 small steps, repeating every octave. 10L 9s is a child scale of 9L 1s, expanding it by 9 tones. Generators that produce this scale range from 1073.7 ¢ to 1080 ¢, or from 120 ¢ to 126.3 ¢. The 10L 9s MOS scale divides its large steps 2-1-1-1-1-1-1-1-1 like the 10edo nonatonic scale. Its 'trienthird' generator falls in the narrow range of 1/10edo (120) to 2/19edo (126.316 cents).

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.
