This is the first edo with a perfect fifth, coming in 18.04¢ sharp of [[3/2]]. Because of how sharp the fifth is, 5edo works best in timbres with quick decay (like a marimba), so that the dissonance of the fifth is softened. Although, the sharp fifth when used melodically has quite a desirable "uplifting" quality that brings it out amidst the texture of the rest of the scale.

This edo also features [[Interseptimal interval|interseptimal intervals]], a very interesting class of intervals characterized by toeing the lines between extreme [[7-limit|septimal]] intervals. There's the 240¢ "second-third", which lies between [[8/7]] and [[7/6]], and the 960¢ "seventh-sixth", which lies between [[7/4]] and [[12/7]]. I'd say 240¢ definitely sounds more like a supermajor second than an inframinor third in most cases, and I find it almost impossible to hear 960¢ as a sixth since it's so close to the 7th harmonic, but it is interesting how these intervals are technically ambiguous.

Oh yeah, did I just mention it has a decent approximation of the 7th harmonic? It's only 8.83¢ flat of 7/4, which is cool because this approximation extends to all 5n-edos. Anyway, the equipentatonic scale that this edo sports is a bit reminiscent of the minor pentatonic scale of 12edo (or, dare I say, the dorian pentatonic scale), making it quite familiar to unaccustomed ears, but still with a tang of xen. In many cases, it is rather difficult to notice if a piece is in this edo if you aren't familiar with it. Because of this, I'd say 5edo is a good starting edo when venturing into xen territory.
