| '''156edo''' is the [[EDO|equal division of the octave]] into 156 parts of 7.6923 cents each. It tempers out 531441/524288 (pythagorean comma) and 1220703125/1207959552 (ditonic comma) in the 5-limit, as well as 1224440064/1220703125 (parakleisma); 225/224, 250047/250000, and 589824/588245 in the 7-limit. Using the patent val, it tempers out 441/440, 1375/1372, 4375/4356, and 65536/65219 in the 11-limit; 351/350, 364/363, 625/624, 1625/1617, and 13122/13013 in the 13-limit. Using the 156e val, it tempers out 385/384, 540/539, 1331/1323, and 78408/78125 in the 11-limit; 351/350, 625/624, 847/845, and 1001/1000 in the 13-limit.

| [[Category:Edo]] | | It [[tempering out|tempers out]] 531441/524288 ([[Pythagorean comma]]) and {{monzo| -27 -2 13 }} (ditonmic comma) in the 5-limit, as well as {{monzo| 8 14 -13 }} ([[parakleisma]]); [[225/224]], [[250047/250000]], and [[589824/588245]] in the 7-limit. Using the patent val, it tempers out [[441/440]], 1375/1372, 4375/4356, and 65536/65219 in the 11-limit; [[351/350]], [[364/363]], [[625/624]], 1625/1617, and 13122/13013 in the 13-limit. Using the 156e val, it tempers out [[385/384]], [[540/539]], 1331/1323, and 78408/78125 in the 11-limit; 351/350, 625/624, [[847/845]], and [[1001/1000]] in the 13-limit. It [[support]]s [[compton]] and gives a good tuning for the 5- and 7-limit version thereof. |

| Welcome to {{PAGENAME}}

| | Sinece 156 factors into {{factorization|156}}, 156edo has subset edos {{EDOs| 2, 3, 4, 6, 12, 13, 26, 39, 52, and 78 }}. It is the smallest edo to contain both [[12edo]] and [[13edo]] as subsets. |
|
| |
|
| =={{PAGENAME}} = [[12edo]] × [[13edo]]== | | == Intervals == |
| | | {{Interval table}} |
| Distinctively interesting choice for an edo, due to its divisibility by both 12 and 13. This means it can be used to play [[12edo]] music and [[13edo]] music at the same time, using the [[K/N|156/13 and 156/12]] vals respectively.
| |
| | |
| ==7.692==
| |
| | |
| {{PAGENAME}} has a step size of {{#expr: 1200.0/156.0}} cents. Microtonal enthusiasts might notice it seems close to the [[225/224]] ratio, but it isn't in the patent val, because {{PAGENAME}} tempers out [[225/224]]. The edo step size closest to [[225/224]], taking into account the primes that compose it, is in [[171edo]]. You have to use the [[K*N|2*156]] val, sacrificing 3 for a new 9, to make this approximation come true. It is up to the microtonalist to decide whether this tradeoff is worth it. | |

156 equal divisions of the octave (abbreviated 156edo or 156ed2), also called 156-tone equal temperament (156tet) or 156 equal temperament (156et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 156 equal parts of about 7.69 ¢ each. Each step represents a frequency ratio of 21/156, or the 156th root of 2.
It tempers out 531441/524288 (Pythagorean comma) and [-27 -2 13⟩ (ditonmic comma) in the 5-limit, as well as [8 14 -13⟩ (parakleisma); 225/224, 250047/250000, and 589824/588245 in the 7-limit. Using the patent val, it tempers out 441/440, 1375/1372, 4375/4356, and 65536/65219 in the 11-limit; 351/350, 364/363, 625/624, 1625/1617, and 13122/13013 in the 13-limit. Using the 156e val, it tempers out 385/384, 540/539, 1331/1323, and 78408/78125 in the 11-limit; 351/350, 625/624, 847/845, and 1001/1000 in the 13-limit. It supports compton and gives a good tuning for the 5- and 7-limit version thereof.
