181edo and stretched hemififths
Normal Hemififths
181edo supports normal Hemififths (MOS 3L 4s) with the mode 31 22 31 22 31 22 22
Stretched Hemififths
This mode can be improved in 181edo by stretching some small "s" with 1 step of 181edo: 31 22 31 23 31 22 23
With this stretched mode, more JI ratios are approximated
