In [[13-limit]] [[just intonation]], '''128/91''' is the '''91st subharmonic''' or '''smaller huntmic tritone''', measuring about 590.6¢. It is [[640/637]] (huntma, about 8.13¢) sharp of [[7/5]], or [[4096/4095]] (schismina, about 0.42¢) sharp of [[45/32]]. Its inversion is the larger huntmic tritone, or octave-reduced 91th harmonic [[91/64]], and the interval that separates them is the small [[comma]] [[8281/8192]], about 18.7¢.
