*Meantone, with a generator size around 696¢, corresponding to a step ratio within the hyposoft range (3:2 to 2:1).

===Ultrasoft to parasoft===
===Parasoft===
Ultrasoft to parasoft tunings correspond to flattone temperaments, characterized by flattening the perfect 5th (3/2) to achieve a diatonic major 3rd that is flat of 5/4 (386¢). Examples of this include 26edo (step ratio 4:3).
:''Main article: [[Flattone]]''
Parasoft tunings (step ratios between 4:3 to 3:2) correspond to flattone temperaments, characterized by flattening the perfect 5th (3/2) so it makes the diatonic major 3rd flatter than 5/4 (386¢). Compatible edos include 26edo, 45edo, and 64edo.

:''Main article: [[Meantone]]''
:''Main article: [[Meantone]]''
Hyposoft tunings correspond to meantone temperaments, characterized by flattening the perfect 5th (3/2) to achieve a diatonic major 3rd that approximates 5/4 (386¢). Examples of this include 19edo (step ratio 3:2) and 31edo (step ratio 5:3).
Hyposoft tunings (step ratio between 3:2 to 2:1) correspond to meantone temperaments, characterized by flattening the perfect 5th (3/2) to achieve a diatonic major 3rd that approximates 5/4 (386¢). Compatible edos include 19edo, 31edo, and 50edo.

===Hypohard ===
:''Main articles: [[Pythagorean tuning]] and [[Schismatic family#Schismatic aka Helmholtz|schismatic temperament]]''
The range of hypohard tunings can be divided into a minihard range (step ratios 2:1 to 5:2) and quasihard range (step ratios 5:2 to 3:1).


{{MOS degrees|Scale Signature=5L 2s|Step Ratio=3/2; 5/3}}
==== Minihard ====
Minihard tunings correspond to Pythagorean tuning and schismatic temperament, characterized by having a perfect 5th that is as close to just (701.96¢) as possible, resulting in 81/64 (407.8¢) for its major 3rd. Compatible edos include 41edo, and 53edo.
{{MOS degrees|Scale Signature=5L 2s|Step Ratio=7/3; 9/4}}


===Hypohard===
==== Quasihard ====
Quasihard tunings correspond to "neogothic" or "parapyth" systems whose perfect 5th is sharper than just, resulting in major 3rds that are sharper than 81/64. Compatible edos include 29edo and 46edo.


===Parahard to ultrahard===
17edo is considered to be on the sharper end of the neogothic spectrum, with a major 3rd that is more discordant than flatter neogothic tunings.
{{MOS degrees|Scale Signature=5L 2s|Step Ratio=5/2; 8/3; 3/1}}
===Parahard and ultrahard===
Parahard and ultrahard tunings (step ratio 3:1 or sharper) correspond to "archy" systems. Compatible edos include 17edo and 22edo.

5L 2s has a parent scale of 2L 3s, meaning 5L 2s contains 2L 3s as a subset. 5L 2s also has two child scales that both contain 5L 2s as a subset: either 7L 5s (if the step ratio is less than 2:1) or 5L 7s (if the step ratio is greater than 2:1). A step ratio exactly 2:1 will produce 12edo, an equalized form of 5L 7s and 7L 5s.
