296edo
| ← 295edo | 296edo | 297edo → |
The 296 equal divisions of the octave (296edo), or the 296(-tone) equal temperament (296tet, 296et) when viewed from a regular temperament perspective, is the equal division of the octave into 296 parts of about 4.05 cents each.
Theory
In the 5-limit, 296et not only tempers out the semicomma of 5-limit orwell (orson) temperament, 2109375/2097152, it also provides its optimal patent val, and tempers out the minortone comma, [-16 35 -17⟩. It is also an interesting temperament in higher limits, being distinctly consistent through to the 15-odd-limit. In the 7-limit it tempers out 4375/4374 (ragisma), 16875/16807 (mirkwai), and 118098/117649 (stearnsma), supporting 7-limit octoid temperament. In the 11-limit, 540/539, 1375/1372, 3025/3024, 4000/3993, 6250/6237 and 9801/9800; in the 13-limit, 625/624, 729/728, 1575/1573, 1716/1715, 2080/2079, and 6656/6655, so that it also supports the 11- and 13-limit versions of octoid.
296 is divisible by 2, 4, 8, 37, 74 and 148.
