| Interval information |
125/121, the jug comma is a 11-limit (also 5.11 subgroup) medium comma of about 56.3 cents. It is the difference between 5/4 and a stack of 2 11/10s or 25/22s.
Etymology
The name for this comma was coined in 2024 by CompactStar, based on the name of juggernaut temperament.
Temperaments
Tempering out this comma in the full 11-limit results in the rank-4 jug temperament. Tempering out this comma in the 2.5.11 subgroup results in the rank-2 jugular temperament, generated by a meantone-like major second of 11/10~25/22, and in the no-twos-or-threes 5.7.11 subgroup it results in the nonoctave rank-2 juggernaut temperament, with a period that is the square root of 5 (representing 11/5~25/11) and a generator of ~7/5. 125/121 is also tempered out in 11-limit flattone, which can be viewed as a weak extension of jugular temperament slicing the generator into 2 fifths.
