1L 2s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 1 large step and 2 small steps, repeating every octave. Generators that produce this scale range from 800 ¢ to 1200 ¢, or from 0 ¢ to 400 ¢. 1L 2s is a trivial 3-tone moment-of-symmetry scale.{{Infobox MOS

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
