Welcome to {{PAGENAME}} | |||
=={{PAGENAME}} = [[12edo]] × [[13edo]]== | |||
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. | |||

Revision as of 15:43, 17 July 2020
156edo is the 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.
156edo
Welcome to 156edo
156edo = 12edo × 13edo
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 156/13 and 156/12 vals respectively.
7.692
156edo has a step size of 7.6923076923077 cents. Microtonal enthusiasts might notice it seems close to the 225/224 ratio, but it isn't in the patent val, because 156edo 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 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.
