'''1L 3s<3/2>''' (or '''neptunian'''), is a fifth-repeating MOS scale with 1 large step and 3 small steps. The name "neptunian" was given by [[User:CompactStar|CompactStar]] in analogy to "uranian" name for [[3L 2s (fifth-equivalent)|3L 2s<3/2>]].
{{MOS intro}} The name "neptunian" was given by [[User:CompactStar|CompactStar]] in analogy to "uranian" name for {{mos scalesig|3L 2s<3/1>|link=1}}.

Due to being a tetratonic scale, neptunian interval classes often line up with diatonic interval classes (at least for L/s <u><</u> 2/1) so similar note names can be used. Although, one difference is that the "perfect fourth" can go up to a subfifth in the most extreme case.

This temperament equates 2 [[11/8]] with [[5/4]]. It contains an 8:10:11 triad, which sounds quite similar to a major triad although with increased tension. [[9edf]] (and thus [[Carlos Alpha]]) is a good tuning for this temperament with its accurate 5/4 and 11/8.
