2L 1s is a trivial 3-tone scale. 2L 1s is one of two halves in the tree of strict MOSes, the other being 1L 2s. 2L 1s is the parent MOS of the pentic scale 2L 3s, which is itself the parent of the diatonic and antidiatonic scales, as well as the antipentic scale 3L 2s, which is itself the parent of the oneirotonic and checkertonic scales.

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.
