'''129/128''', or the '''43-limit Johnston comma (HEJI)''', is a 2.3.43 subgroup comma. It is the amount by which 43/32 (the 43rd harmonic) exceeds the perfect fourth (4/3). It is significant in [[Helmholtz-Ellis notation]] as the formal comma to translate a Pythagorean interval to a nearby 43-limit (prefix???) interval.
