29- and higher-limit accidentals
Could someone please do the 29-limit and higher accidentals? This has been a "TODO" for a while now. [math]\displaystyle{ \overrightarrow{\,\,\scriptsize\text{ArrowHead294}\,\,\,} }[/math] (speak to me) 13:24, 22 May 2024 (UTC)
23-limit vs syntonic comma arrows
I don't know if this is anything you can actually do anything about (if it's the actual standard, it's the actual standard), but those 23-limit comma arrows look EXTREMELY SIMILAR to single syntonic comma arrows, with the only discernable difference that the syntonic comma arrows are shown attached to other accidental symbols, whereas the 23-limit comma arrows are shown by themselves.

Typo in Latest revision as of 2024-11-19T14:22:59?
Latest revision says "
is n a half-sharp, as F is 7.1¢ flatter than F♯." (used to have not instead of n). Is this a typo/copy-paste error? Lucius Chiaraviglio (talk) 20:18, 19 November 2024 (UTC)
- FloraC fixed it in revision of 2024-11-21T04:39:55. Lucius Chiaraviglio (talk) 11:10, 21 November 2024 (UTC)
31-limit schisma and 41-limit comma symbols
I don't know if you can do anything about it (if it's the standard, it's the standard), but the symbols for up/down by 31-limit schisma look extremely similar to the symbols for up/down by 41-limit comma. Lucius Chiaraviglio (talk) 07:30, 12 July 2025 (UTC)
- The 31-limit schismata come from the deprecated pre-2020 version. Since 2020 the quartertone accidentals have been standard. I split off the deprecated symbols to hopefully make this clearer. FloraC (talk) 13:36, 12 July 2025 (UTC)
- Okay, thanks, it makes sense now. (And then we have to wait for whoever is in charge of the Helmholtz-Ellis standard to realize that the 23-limit symbols could cause confusion). Lucius Chiaraviglio (talk) 19:00, 12 July 2025 (UTC)
Dual-value harmonics (Helmholtz-Ellis edition)?
What notation should one use for systems with dual values for a harmonic? For instance, 55edo has a 7th harmonic that is far enough from just to merit interpretation as 7♯ with only mostly more raw error than 7♭, and the 7♯ would actually introduce less error in combination with the sharp (but not split) 5th harmonic, while 7♭ would introduce less error in combination withe flat 3rd and 11th harmonics or by itself. Similar situations occur with 48edo and 67edo with their split 5th harmonics, and with any dual-fifth system. Lucius Chiaraviglio (talk) 09:15, 24 August 2025 (UTC)
