2L 1s⟨3/2⟩ is a 3/2-equivalent (fifth-equivalent) moment of symmetry scale containing 2 large steps and 1 small step, repeating every interval of 3/2 (702.0 ¢). Generators that produce this scale range from 234 ¢ to 351 ¢, or from 351 ¢ to 468 ¢. Scales of this form are always proper because there is only one small step.

Scale properties

This article uses TAMNAMS conventions for the names of this scale's intervals and scale degrees. The use of 1-indexed ordinal names is reserved for diatonic interval categories.
