193 equal divisions of the octave (abbreviated 193edo or 193ed2), also called 193-tone equal temperament (193tet) or 193 equal temperament (193et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 193 equal parts of about 6.22 ¢ each. Each step represents a frequency ratio of 21/193, or the 193rd root of 2.

Theory

193edo is consistent to the 11-odd-limit, and almost consistent to the 23-odd-limit, the only failure being 13/11 and its octave complement. This makes it a strong 23-limit system.

As an equal temperament, it tempers out the kleisma in the 5-limit; 5120/5103 and 16875/16807 in the 7-limit; 540/539, 1375/1372, 3025/3024, and 4375/4356 in the 11-limit; 325/324, 364/363, 625/624, 676/675, 1575/1573, 1716/1715, and 4096/4095 in the 13-limit; 375/374, 442/441, 595/594, 715/714, 936/935, 1156/1155, 1225/1224, 2058/2057, and 2431/2430 in the 17-limit; 400/399, 969/968, 1216/1215, 1445/1444, 1521/1520, 1540/1539, and 1729/1728 in the 19-limit; and 460/459, 507/506, and 529/528 in the 23-limit.

It provides the optimal patent val for the sqrtphi temperament in the 13-, 17- and 19-limit, and for the 13-limit minos and vish temperaments.
