319edo is [[consistent]] to the [[7-odd-limit]], but [[harmonic]] [[3/1|3]] is about halfway its steps. The full 11-limit [[patent val]] is nonetheless a reasonable interpretation since the lower harmonics all tend sharp. Using this val, it [[tempering out|tempers out]] [[6144/6125]], [[10976/10935]], and {{monzo| 9 -10 9 -5 }} in the 7-limit; [[3025/3024]], [[4000/3993]], [[6250/6237]], 15488/15435, 59290/59049, and [[65536/65219]] in the 11-limit. It [[support]]s [[mystery]] in the 5-limit and [[protolangwidge]].

===Odd harmonics===

If we instead adopt the 2.9.… [[subgroup]] interpretation, then 2.9.15.21 is a good subgroup to start with.

319 factors into 11 × 29, ~~with~~ [[11edo]] and [[29edo]] as its ~~subset edos~~. [[638edo]], which doubles it, gives a good correction to the ~~harmonic~~ 3.

Since 319 factors into 11 × 29, 319edo has [[11edo]] and [[29edo]] as its subsets. [[638edo]], which doubles it, gives a good correction to the harmonics 3, 5, and 7.
