Introduction
As of now, EDO impressions are mostly melodic rather than harmonic.
EDO Impressions
Note: They are by no means final!
12: We've all heard this system thousands of times before.
17: The diatonic scale has a septimal flavor to it, with major thirds sounding nothing like 12edo ones. The minor second is the perfect size melodically, though it may take a while to get used to it.
19: Due to the flat tendency of the system, melody seems to have a feeling that is hard to describe, that you can't replicate with 12edo. So far my biggest issue is that the minor seconds are too wide.
