: '''Vector:''' Our first [[mavila]] edo! I'm not a huge fan of this tuning, because of all the enharmonic notes it gives in mavila. It's the first time we have a distinction between normal major and minor chords, though.

: '''Budjarn Lambeth:''' Offers exciting melodic shapes, but requires careful attention to timbre to prevent it sounding "out of tune".

: '''Zhenlige:''' A subset of [[ennealimmal]].

: '''Zhenlige:''' A stack of [[7/6]]. A subset of [[ennealimmal]].

: '''Eufalesio:''' Potentially useful, but I don't really like it. D

: '''Deja Igliashon:''' if this EDO got as much attention as [[31edo]], the world would be a better place. For many EDOs, getting into the particulars of how they [[temper]] extended [[JI]] is kind of unnecessary to really appreciate them, but 27edo is just so disgustingly ELEGANT in how it tempers that it makes it SO MUCH EASIER to navigate extended JI than darn near anything that can approach it in [[accuracy]]. First, consider the [[unison vector]] 64/63: just like {{EDOs|5, 10, 15, 20, 22, and 25edo}} (and I guess 12d?), tempering this out makes it so you can divide [[7/4]] into two equal parts that are each equal to [[4/3]], so even a short [[chain of fifths]] just automagically incorporates a bunch of ratios of 7. Then you've got [[128/125]], aka the Augmented comma, aka the diesis or something, which makes it so three approximate [[5/4]]s span exactly one octave--if you simply follow a chain of 5/4s, you literally can't get lost in the tuning! So far so good but also [[15edo]] can do both of these as well, so what else do we have? How about the holy trinity of 144/143, 169/168, and 196/195, the vanishing of which make it so [[12/11]]=[[13/12]]=[[14/13]]=[[15/14]]? This is the trinity that really gives 9edo its mojo, and in 27edo we have three parallel closed circles of [[9edo]], offset from one another by 1 and 2 steps of 27edo (respectively). Why is this cool? Because if you have a root note on one chain of 9edo, you have a [[5/4]] above it on the same chain, and then you have [[11/8]], [[3/2]], [[13/8]], [[7/4]], and [[15/8]] on the next chain of 9edo that's 1\27 higher. So you can just arpeggiate a bunch of [[harmonic]]s using motion by a single uniform step size, and if you keep moving by that same step size, instead of getting lost or circulating through ALL THE NOTES OF THE TUNING, you end up back at familiar territory after just a few off-kilter notes. Basically 27edo just makes it really easy not to get lost in [[15-odd-limit]] JI, because you have can find your way between harmonics with simple motions on small closed circles. Just AMAZING!

: '''Fumica:''' The cyberpunk edo. Good sharp-tending tuning profile in the 2.3.5.7.13 [[subgroup]] with the sole exception of harmonic 15 tuned way too sharp, for I prefer a flat tuning of 15 or at least no sharper than 12edo's to improve its stability as a consonant major seventh. Other than that it's pretty good. Octave compression gives better intonation. A-tier.

: '''Zhenlige:''' ~~A stack of [[7/6]].~~ Worse than both 12- and 22edo for 5-limit. Its fifth sucks and its diatonic scale makes little sense. Its 7/3 and 7/5 are good, but 3, 5 and 7 are off. Use [[108edo]] to make it a true 7-limit EDO, and [[270edo]] is excellent. When I hear its ~[[10:12:15]] and ~[[6:7:9]] chord I feel the fifth is obviously off. I have listened to both 22edo and 27edo and I feel the former is better. Compared to 22edo, it is like fixing 7 by ruining 5 and partly 3. There are beatings here and there. It really needs compression. The fact that [[53edo]] is good indicates that 26- and 27edo are probably bad.
