13 EDO

How do you notate 13 EDO? It's weird because father is an 8 note scale while glacial being a 7 note scale is not built from a chain of fifths.

Ah ok that makes sense just like 11 is every other note of 22.Dave Keenan wrote:In the Xenharmonikon article we recommend notating it as every 3rd note of 39-edo. But Cryptic Ruse has just made a reasonable case for notating it as every second note of 26-edo.
