The guidelines
These are draft guidelines for what a standard "related tunings"-type section should look like on edo pages, using 36edo as an example.
- Which tunings should be listed for any given edo
- The edo's pure-octaves tuning
- 1 to 3 nearby edonoi (eg an edt, an edf, an ed5, an ed7, an ed4/3, anything like that)
- 1 to 2 nearby ZPIs (or any other "infinite harmonics" optimised tuning other than ZPI)
- 1 to 2 subgroup TE- or WE-optimal tunings, based on the best choice(s) of subgroup for the edo
- 1 other equal tuning of any kind at all (optional)
Additional guidelines for selecting tunings:
- In total, roughly 6 tunings should be listed, give or take a few.
- The selection of tunings should cover a range of meaningfully different tunings (eg they cover a range of different mappings and/or they approximate different harmonics well or badly).
- Further instructions
- Adding the comparison table at the end is optional.
- The number of decimal places to use in the comparison table is up to the user's discretion, as long as it is self-consistent within the table.
- Where this section should be placed on an edo page
- Synopsis & infobox
- (Any foundational introductory subsections)
- Theory
- Harmonics
- (Any short subsections about theory unique to the edo)
- Additional properties
- Subsets and supersets
- Interval table
- Notation
- (Any long subsections about theory unique to the edo)
- Approximation to JI
- Regular temperament properties
- Uniform maps
- Commas
- Rank-2 temperaments
- OCTAVE STRETCH OR COMPRESSION
- Scales
- (Any subsections about practice unique to the edo)
- Instruments
- Music
- See also
- Notes
- Further reading
- External links
Note: This particular set of headings in this order is only how most edo pages look at the moment, but it might be replaced with a more intuitive standard in the future. If and when that happens, this guideline should be modified to adopt that new standard.

Example (36edo)
Octave stretch or compression
What follows is a comparison of stretched- and compressed-octave 36edo tunings.
- Step size: 33.426 ¢, octave size: 1203.351 ¢
Stretching the octave of 36edo by a little over 3 ¢ results in improved primes 5, 11, and 13, but worse primes 2, 3, and 7. This approximates all harmonics up to 16 within 13.4 ¢. The tuning 21edf does this.

- Step size: 33.368 ¢, octave size: 1201.235 ¢
If one intends to use both 36edo's vals for 5/1 at once, stretching the octave of 36edo by about 1 ¢ optimises 36edo for that dual-5 usage, while also making slight improvements to primes 3, 7, 11, and 13. This approximates all harmonics up to 16 within 16.6 ¢. Several almost-identical tunings do this: 57edt, 93ed6, 101ed7, 155zpi, and the 2.3.7.13-subgroup TE and WE tunings of 36et.

- Step size: 33.304 ¢, octave size: 1198.929 ¢
Compressing the octave of 36edo by about 2 ¢ results in much improved primes 5 and 11, but much worse primes 7 and 13. This approximates all harmonics up to 16 within 11.6 ¢. The 11- and 13-limit TE tunings of 36et both do this, as do their respective WE tunings.

Plan for roll-out
Edo pages which currently have an "octave stretch", "related tunings", "zeta properties", etc. section:
- Done (with table): 36.
- Done (table not added yet): 7, 8, 12, 14, 16, 17, 19, 22, 23, 27, 31, 41, 58, 72, 99.
--
- High priority pages: 60, 32, 33, 39, 42, 45, 54, 59, 64.
- Medium priority pages: 118, 13, 103, 111.
- Low priority pages: 104, 125, 145, 152, 159, 166, 182, 198, 212, 243, 247.
- This standard will need to be rolled out to those above pages.
It can optionally be rolled out to other edo pages later:
- Some that might be of interest: 25, 26, 29, 30, 34, 35, 37, 5, 6, 9, 10, 11, 15, 18, 48, 20, 24, 28.
- Things to note
- When rolling it out try not to delete existing body text but instead rework it where possible.
- This section will not replace any "n-edo and octave stretch" pages. Still, add this section to the relevant edo page, but also link to the "n-edo and octave stretch" page at the top of this section, using the see also Template, e.g.: "{{See also|36edo and octave stretch}}".
What to do with edonoi pages that are very close to these edos
- Edt and edf pages should be permanently kept
- Other edonoi pages should be temporarily kept until all notable information from their respective pages has been added to:
- The "octave stretch and compression" section of the edo page.
AND/OR
- A new "Nedo and octave stretch" page (create one of these if there is too much information to squeeze into the "octave stretch and compression" section).
Possible tunings to be used on each page
You can remove some of these or add more that aren't listed here; this section is pretty much just brainstorming.
(Used https://x31eq.com/temper-pyscript/net.html, used WE instead of TE cause it kept defaulting to WE and I kept not remembering to switch it)
