319et is consistent to the [[7-odd-limit]] and the [[harmonic]] 3 is about halfway its steps. Using the patent val, it tempers out 156250000/155649627, 1220703125/1219784832, [[6144/6125]], [[10976/10935]] and 420175/419904 in the 7-limit; 95703125/95664294, 161280/161051, 35156250/35153041, [[4000/3993]], 117649/117612, 1296000/1294139, [[6250/6237]], 107495424/107421875, 4302592/4296875, 825000/823543, 422576/421875, 15488/15435, [[3025/3024]], 59290/59049, 766656/765625, 456533/455625, 202397184/201768035, 3294225/3294172, 585640/583443 and 644204/643125 in the 11-limit. It [[support]]s [[mystery]] in the 5-limit and [[protolangwidge]].
319edo is [[consistent]] to the [[7-odd-limit]], but [[harmonic]] [[3/1|3]] is about halfway its steps. Nonetheless, it provides the optimal patent val for 5-limit [[mystery]] temperament, which tempers out the [[29-comma]], despite poor 5-limit harmonic approximation.


===Odd harmonics===
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]].
 
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.
