## 13/11-kleisma

How can this name be derived that it's called fairly intuitive? Please help me understand! --Xenwolf (talk) 08:26, 28 September 2020 (UTC)

- Fact 1: 352/351 = (32/27)/(13/11). This says it is how much 13/11 deviates from a Pythagorean interval, hence "13/11-kleisma".

- Fact 2: 352/351 = (1053/1024)/(33/32). This says it is the difference between the tridecimal quartertone and undecimal quartertone, hence "13/11-kleisma".

- The reason why it's of significance is that there's a dedicated symbol for 352/351~5120/5103 in sagittal notation, and this is how they call it. FloraC (talk) 08:48, 28 September 2020 (UTC)

- Is
*352/351~5120/5103*the official notation for tempering out the interval between the both explicitly given intervals? I also read*=*instead some days ago. Both seem quite intuitive, the equals sign is catchier but also more challenging from the mathematical POV. --Xenwolf (talk) 10:10, 26 November 2020 (UTC)
