This mode can be improved in 181edo by stretching some "s" of the mode with 1 step of 181edo: 31 22 31 23 31 22 23
This mode can be improved in 181edo by adding 1 more step on the fifth, and 1 more step on the octave: 31 22 31 23 31 22 23


With this stretched mode, more JI ratios are approximated thoughout the octaves
With this stretched mode, various simple [[Just intonation|Just Intonation]] ratios are approximated thoughout the octaves.
