reduced
The ursulisma, or ursulic comma, is a 17-limit (also 2.3.5.11.17 subgroup) superparticular comma with a ratio of 375/374. It is the interval that separates 17/15 from 25/22, as well as separating 25/17 from 22/15.
Commatic relations
This comma identifies itself as the difference between the following superparticular pairs:
- 100/99 and 136/135
- 120/119 and 176/175
- 225/224 and 561/560
- 273/272 and 1001/1000
- 325/324 and 2431/2430
- 364/363 and 12376/12375
It factors into the following superparticular pairs:
Not to mention some nonsuperparticular but useful relations:
Temperaments
Tempering out this comma in the 17-limit leads to the rank-6 ursulismic temperament. Tempering it out in the 2.3.5.11.17 subgroup leads to the rank-4 ursulic temperament. Both enables ursulismic chords.
Etymology
The ursulisma was named by Aura and VIxen in 2023. It refers to 375 Ursula, the asteroid. After some naming attempts in the XA Discord Server that tuned out dissatisfactory to the participants, VIxen came up with the idea to look up the list of minor planets in case everything else failed, and Aura was the first to put together the word ursulisma.
