Hemipyth implies (P8/2, P5/2) pergen; Alpha-dicotpyth implies (P8, P4/2), (P8, P5/2) is a subset of hemipyth.


The nomenclature is called EPN and EHPN (Eufa's Pythagorean Nomenclature and Eufa's HemiPythagorean Nomenclature). It is based on [[User:Eufalesio/PLIN|some other musings I did]].

=== General case ===
Not used necessarily with just fifths, can use ideally with fifths between 24\41 and 38\65 inclusive.
* Use normally for any tunings with fifths inside that range.
* Fifths wider than 10\17 have to use m2 fractions as the mapped poma is far too big
* Compton has to use aug/dim fractions
* Fifths flatter than 7\12 now use d2 to refer to sub/super prefixes, the meantone diesis
* Fifths flatter than 11\19 have to use aug/dim fractions because the mapped meantone diesis is far too wide
