-'''128/81''' is the '''Pythagorean minor sixth''', created by stacking for instances of [[4/3]] and [[Octave reduction|octave-reducing]].  In contrast to the more typical [[8/5]]- with which it is conflated in [[meantone]]- this interval has a [[harmonic entropy]] level roughly on par with that of [[12/11]].  Thus, some would argue that it is functionally an imperfect dissonance.
