Different ways edos I deem important map intervals, made mostly for myself for notekeeping but may be useful to you.
Different ways edos I deem important map intervals, made mostly for myself for notekeeping but may be useful to you. Nomenclature is a mix of my [[User:Eufalesio/Holopyth and Hemipyth|Holopyth and Hemipyth]] and [[Kite's ups and downs notation]], but resumed: sub/super/hypo/hyper add -1/+1/-2/+2 mapped pythagorean commas, up/down add edosteps.
 
Before going into the tables: edos listed here are 
 
== Meantonoids* ==
Edos that temper the syntonic comma '''in the golden series'''. Up/down can be used for diesis halves.
 
* 19edo is coarse, decent 5-limit.
* 31edo has a great 11-limit, usable 13-limit, still a bit coarse.
* 50 has a worse 7-limit, but better overall 19-limit.
* 62edo greatly improves upon 31edo expanding it to the 23-limit. Finest reasonably usable meantone edo.


== Meantonoid edos ==
Edos that temper out the syntonic comma, in the golden series.

<nowiki>*</nowiki>Treating super/sub as meantone dieses (d2) not pythagorean commas.
== Comptons ==
Edos that temper out the [[Pythagorean comma|poma]]. Not using up/down in 24edo because up/down differ too much in size from 72 and 84. The mapping of up/down is obviously fractions of 1\12.
* 72edo has an astounding 11-limit, usable in the 19-limit.
* 84edo has a great 2.3.5.7.13, worse 11.

Treating super/sub as meantone dieses (d2) not pythagorean commas
== Panschismoids ==
Edos that have very accurate fifths and temper out very small or unnoticeable commas.


== Schismoid edos ==
* 41edo has a great 11-limit, usable no-17,23 29-limit
Edos that temper the schisma(s) or garischisma(c), or both(g).
* 53edo has an extremely accurate 2.3.5.13.19, decent 13-limit.
* 94edo has a well-rounded 23-limit with good accuracy.
 
=== Cassandroids ===
Have fifths close to just, supporting garibaldi. Up/down can be used for pc halves (or mercommas) in the case of 94edo.

=== Helmholtzoids ===
Have fifths a smidge flatter than just, along the optimal range for schismic and pontiac. Up/down can be used for pc fractions. The true mappings for 171 and 224's edostep are -53 fifths (negative merccomma). 130 and 159 instead have a poma fraction as the only possible reasonable mapping.
 
* 130 has a well rounded 13-limit with very good accuracy, usable all the way to the no-29 31-limit.
* 159 has an unfathomably accurate 2.3.11, extremely accurate 2.3.5.11.17, usable in the no-17 29-limit.
* 171 has an unfathomably accurate 7-limit. Usable in the no-11 19-limit.
* 224 has an extremely accurate 13-limit. Bad for higher limits.

=== Non-cassandroid Ultimates ===
Have fifths a smidge sharper than just, along the optimal range for [[Cassaschismic|cassaschismic (Ultimate)]]. Up/down can be used for pc fractions.
 
{{Databox|The true mappings of the up/down are contrived.|41-comma (transsuperunison) for 217edo<br>53-comma - half poma (transsemisubunison) for 270edo<br>135-comma for 311edo<br>also -41 hemififths (sesquisubbarbaric) for 270edo and 311edo}}
* 217 has a well rounded 31-limit with great accuracy.
* 270 has an astonishingly accurate yazalathana. Usable in higher limits.
* 311 has a well rounded 41-limit with great accuracy.
