In Just Intonation, 127/72 is the frequency ratio between the 127th and the 72th harmonic.
It is the mean between the [[7/4|harmonic seventh]] and the [[16/9|Pythagorean minor seventh]]: (7/4 + 16/9)/2 = 127/72.
It can also be calculated from the [[64/63|septimal comma]]: ((64/63 - 1)/2 + 1)⋅(7/4) = 127/72.
