952 equal divisions of the octave (952edo), or 952-tone equal temperament (952tet), 952 equal temperament (952et) when viewed from a regular temperament perspective, is the tuning system that divides the octave into 952 equal parts of about 1.26 ¢ each.
Theory
In the 2.3.13.17.19 subgroup, 952edo tempers out 793152/793117.
In the 19-limit as a whole, 952edo tempers out 1445/1444, 1540/1539.
952edo is notable for having a concoctic scale which represents a natural phenomenon - 169\952 is useful both as a cycle length for a leap week calendar and its generator, thus being associated with a 169 & 952 mos sequence. The resulting calendar has a year length of 365 days 5h 49m 24.7s. 169/952 of a week, 1d 5h 49m 24.7s is roughly the fraction by which Earth's year length exceeds 52 weeks. The leap day cycle of 33\136 shares the exact same property of concoction, thus 952edo can be viewed as a compound of 7 such MOSes.
Despite having bad approximations, in light of having 28 as a divisor 952edo provides the optimal patent val for the oquatonic temperament in the 7-limit.
