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.
==Selected just intervals by error==
The following table shows how [[15-odd-limit|some prominent just intervals]] are represented in 156edo (ordered by absolute error).
