Errors in edolists
The edolists are very flawed. How is 53edo a dominant meantone?! PiotrGrochowski (info, talk, contribs) 15:59, 10 October 2018 (UTC)
Typo in Septimal Meantone section?
In the Septimal Meantone section, it says that nine fifths are needed to reach the interval for 7, C ~ A#. I count ten fifths, and so does the Wikipedia article on Septimal Meantone Temperament.
| Note | Fifthspan |
|---|---|
| C | 0 |
| G | 1 |
| D | 2 |
| A | 3 |
| E | 4 |
| B | 5 |
| F# | 6 |
| C# | 7 |
| G# | 8 |
| D# | 9 |
| A# | 10 |
Edit: And the table in the Meantone vs Meanpop page also says ten fifths for C - A#.
Are we missing something?

- It seems like an error indeed, good catch. --Fredg999 (talk) 04:59, 22 July 2024 (UTC)
- I wonder if the error arose because whoever typed it was looking at the monzo [-17 9 0 1⟩ = 137781/131072 for the flattone comma (not sure if that is an official name), which maps 9 fifths (octave-reduced) to 8/7 as D♯ and thereby 9 fourths (octave-reduced) to 7/4 as B♭♭, and then they typed it into the septimal meantone description by mistake? (Unfortunately this comma doesn't currently have its own page as far as I can tell, although if it doesn't have an official name, not having its own page isn't surprising -- maybe also the problem for some of the other septimal extensions commas?)

Sharptone?
Still trying to figure out why sharptone exists as a septimal extension to meantone, when the only EDO it seems to really work for (that is, without a 'd' wart) is 5EDO, and then the other equal temperaments listed under it are 12d and 7d (the latter being way over on the flat end of the usable meantone tuning spectrum); meanwhile, Dominant also works for 5EDO, since B♭ is enharmonic to A in 5EDO. Seems like this name should have been saved for a more useful subset of the sharp approximate half of the meantone tuning spectrum. Lucius Chiaraviglio (talk) 12:04, 19 August 2024 (UTC)
Commas listed in Extensions?
Shouldn't the commas listed under Extensions also appear in the comma lists of the respective sub-temperaments listed later on? Lucius Chiaraviglio (talk) 22:08, 23 August 2024 (UTC)
