'''9L 2s<3/1>''' or '''sub-[[Arcturus]]''' is a [[tritave]]-repeating [[MOS scale]] having 9 large steps and 2 small steps. This MOS family is the simplest tritave-equivalent scale using an "ordinary" ~5:3 as a generator. Of course, it is on the extremely flat end of what is "ordinary", being the same size as a neutral sixth. Coincidentally, its categorical name in this scale happens to be "sixth" also, just not in the "ordinary" diatonic sense of the name. Because this "sixth" is so flat, "sixths" in the range of propriety lead, in three steps, when tritave reduced, into the Mavila continuum and the bottom of the syntonic continuum.

== Name ==
The name '''ultratriatonic'''{{idio}} was coined by {{u|ArrowHead294}}, as a back-formation from the name "ultradiatonic" for the octave-equivalent [[9L&nbsp;2s]] scale with di- being interpreted as 2 (the [[2/1|octave]]) and tri- being interpreted as 3 (the [[3/1|tritave]]). It is not an official name in [[TAMNAMS]].
