1323 equal divisions of the octave (1323edo), or 1323-tone equal temperament (1323tet), 1323 equal temperament (1323et) when viewed from a regular temperament perspective, is the tuning system that divides the octave into 1323 equal parts of about 0.907 ¢ each.

Theory

1323edo is the smallest uniquely consistent EDO in the 29-odd-limit.

It provides the optimal patent val for the 11-limit trinnealimmal temperament, which has a period of 1\27 octave.

1323's divisors are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, of which 441EDO is a member of the zeta edos. 1323edo shares the 7-limit mapping with 441edo. As such, it can be interpreted as an improvement for 441edo into the 29-limit by splitting each step of 441edo into three.
