9edo is the first edo with 2 flavors of thirds. It is notable for its uncanny approximations of septimal intervals down to a fraction of a cent. These intervals have an almost ghostly quality to them, giving this edo an incredibly unique, resonant sound that other edos of this scale simply cannot match.


This edo, while I put it in low B tier, is actually a very fun edo. It is, what most people would say, the first edo with 2 flavors of thirds, featuring the familiar 400¢ major third because it's divisible by 3, but also a scarily close approximation of 7/6. In fact, this edo approximates many septimal intervals down to the decimal point, which is quite strange, but definitely contributes to its sound. The fifth is heinously flat (over 30¢ flat of 3/2), but I've found that even this fifth can be softened via the use of a honky-tonk piano timbre. The distinct septimal resonance of the subminor third juxtaposed with the abhorrently flat fifth is an almost ineffable combination, but one that creates some of the most beautiful harmonies. The only reason I put this temperament so low is because the fifth is so flat, so it really is pretty difficult to listen to if you're not using a timbre that is literally out of tune. Plus, there are other edos that support [[Mavila]] with much better fifths. Overall, while the tuning isn't very versatile, the sounds it makes are utterly phantasmagoric, and I highly recommend you try this temperament in a harmonic context.
For example, the juxtaposition of the 266.67¢ subminor third (nearly exactly 7/6) and the 400¢ major third (the one from 3edo) is totally jarring. The incredibly acrid fifth also contributes to the general vibe of resonant septimal consonances battling against sour dissonances. It's an ineffable combination of opposing stimuli, giving this edo an unmistakable sound.
 
9edo is also the first edo to support [[mavila]] temperament, being one of 3 that support it natively in the [[patent val]]. It's certainly an extreme mavila temperament, but making the fifth any sharper would get rid of the septimal consonances, so this particular way of approaching mavila is truly unique.
 
As this edo is right on the border of what I consider to be the macrotonal edos, 1 degree of 9edo has a particular quality to it that makes it sound like a semitone in some contexts and a neutral second in other contexts. My piece ''[https://www.youtube.com/watch?v=1D2_6LsRsPM Elegy of the Willow]'' illustrates this by including many chromaticisms, sometimes in the context of a chromatic scale and sometimes in the context of cadential motion.
 
Other inspiring works in this temperament include [https://youtu.be/O9fJnq-WkqQ?si=3tIsJpfrOHkWZLt2 ''Buttered Cat Paradox''] by Xolta and [https://youtu.be/oXe1mSIMrho?si=_dX7MiN3AgVPPnXm ''Caelum''] by miaxia. ''Caelum'' especially illustrates the nature that I've described, leading me to believe 9edo works best in such a style. The demo I wrote for this edo, however, is nowhere near the style of any of these pieces, yet I think it works quite well. The aforementioned "ghostly" quality of 9edo, particularly the fifth, gives the tango an "abandoned" quality that would fit well in an abandoned ghost town, like the Hidden Village from The Legend of Zelda: Twilight Princess.
 
Overall, a very solid edo. You can choose to avoid the dissonant fifth or embrace it, with both approaches leading to an incredible sound. It's surprisingly versatile, more so than any edo smaller than it, putting it above 7edo. More people should use 9edo.
