"stacking 3 wholetones" is not what tritone means in this context
Line 216: Line 216:


In 13edo, 11/8 and 16/11 map to the tritones 6\13 and 7\13, respectively, and are valid generators for it.  Furthermore, although 12\26 is not valid as a generator for 26edo with a whole-octave period, it ''is'' valid with a half-octave period, for a temperament analogous to [[Injera]] but substituting 11/8 for 4/3.

Note that many temperaments that can use 11/8 as a generator do ''not'' have it as a tritone — for instance, 11/8 (or 16/11) is an excellent generator for [[24edo]], but in 24edo, a stack of 3 whole tones (9/8) is the semioctave, the same as in [[12edo]] apart from being represented by twice as many EDO-steps.
