-The interval can be treated equally either as a comma, which results in the [[Ripple family]], or as a melodic interval in its own right, where it is exactly replicated in 5/12-comma meantone. The 5/12CM-meantone is represented well in [[400edo]], where 6561/6250 is approximated by 28 steps and the generator fifth by 231 steps.
