375et is only consistent to the [[3-odd-limit]] and the harmonic 3 is about halfway between its steps. It can be used in the 2.9.5.7.13.17.19 [[subgroup]]. Using the patent val, it tempers out 40500000/40353607, 52734375/52706752 and [[6144/6125]] in the 7-limit; 100663296/100656875, 10333575/10307264, 166698/166375, 759375/758912, 151263/151250, [[540/539]], 4302592/4296875, 825000/823543, [[5632/5625]], 16808715/16777216, 1362944/1361367, 4108797/4096000, 67110351/67108864, 805255/802816 and [[1771561/1769472]] in the 11-limit. It [[support]]s [[aufic]] and [[persephone]].
375edo is in[[consistent]] to the [[5-odd-limit]] and [[harmonic]] [[3/1|3]] is about halfway between its steps. It can be used as a temperament in the 2.9.5.7.13.17.19 [[subgroup]], in which it [[tempering out|tempers out]] [[250047/250000]], 589824/588245, and {{monzo| 8 7 -13 }} ([[parakleisma]]).
 
For the full 7-limit, the 375cd [[val]] is the best, where it tempers out [[1029/1024]] and [[15625/15552]], [[support]]ing [[tritikleismic]]. In the 11-limit it tempers out [[385/384]] and [[441/440]], supporting undecimal tritikleismic.
 
Using the [[patent val]], it tempers out [[6144/6125]] and 177147/175616, supporting [[aufo]]. In the 11-limit it tempers out [[540/539]] and [[5632/5625]], supporting [[aufic]] and [[persephone]].

375 factors into 3 × 5<sup>3<sup> with subset edos {{EDOs|3, 5, 15, 25, 75, and 125}}. [[1175edo]], which triples it, gives a good correction to the harmonic 3 and is consistent to the [[15-odd-limit]].
Since 375 factors into 3 × 5<sup>3</sup>, 375edo has subset edos {{EDOs| 3, 5, 15, 25, 75, and 125 }}. [[1175edo]], which triples it, gives a good correction to the harmonic 3 and is consistent to the [[15-odd-limit]].
