'''13.888edo''', also known as '''1 equal division of 86.4¢''' ('''1ed86.4c''') or '''arithmetic pitch sequence of 86.4¢''' ('''APS86.4¢'''), is an [[Equal-step tuning|equal-step]] scale generated by | '''13.888edo''', also known as '''1 equal division of 86.4¢''' ('''1ed86.4c''') or '''arithmetic pitch sequence of 86.4¢''' ('''APS86.4¢'''), is an [[Equal-step tuning|equal-step]] scale generated by dividing [[2/1]] into 13.888 equal parts of about 86.4 cents each. | ||
Because 13.888 is not actually an integer, the scale that results does not actually include [[2/1]], so it is not a ''true'' [[edo]]. Instead it has a [[pseudo-octave]] almost 10 cents sharp. | |||
13.888edo has been voted "monthly tuning" multiple times on the [[Monthly Tunings]] Facebook group, owing to its unexpectedly close approximations of many harmonics, but especially [[3/1]], [[7/1]] and [[11/1]]. | |||
It is very close to [[Table of zeta-stretched edos|zeta-stretched 14edo]]. | It is very close to [[Table of zeta-stretched edos|zeta-stretched 14edo]]. | ||
