Some 23-EDO Stuff

Hey all, just posted a new "video" to my YouTube channel demonstrating some of the main heptatonic MOS scales found in 23-EDO.

http://www.youtube.com/watch?v=Hqst8MaRiYM

They're just rough little improvs, they don't really go anywhere, but they do give a fair impression of some of the moods of these scales. In order, the scales I used are:

3343334, 5225252, 3335333, and 5151515. The first is a form of Mavila temperament, but it's very different in character from 16-EDO. I like this version better, actually...it feels more consonant. The second is sort of a cross-breed of Dicot and Father, where the generator is a very flat major 3rd and two of them form a very sharp fifth. It's improper and that leads to some pretty interesting consequences, like a minor 3rd being a 9/8 while the major 2nd is a 7/6. The third is superficially reminiscent of Porcupine[7] but the harmonies are very different--two generators is still a 6/5, but four is either a 10/7 or a 13/9 (depending on your mood) instead of a 16/11, five is an 11/7 instead of 8/5, and 6 is a 12/7 instead of a 7/4. The fourth scale is maybe Myna temperament, maybe not (depending on whether you're listening to Graham Breed or Paul Erlich). The generator is a 6/5 and two of them gets you a 10/7, but the approximations to the 3rd and 5th harmonics are, uh, "questionable". I don't know why anyone would use it for full 7-limit harmony but it's pretty solid as a 2.5/3.7/3 subgroup. The scale itself is pretty out-there, though...it sounds kind of like two diminished chords tuned a quarter-tone apart, but I kind of love the shimmering "double minor" effect of playing a 6/5 and a 7/6 simultaneously.

Well, enjoy! (Or not)

Igs,

I know these were just designed to "give a fair impression of some of
the moods of these scales", but they were really good and interesting.
Thanks for posting them. I especially liked the second one.

Regards,
Jake

I like the last one best myself.

Same here, and I was wondering what it would sound in in other versions of Myna[7], presuming I can call this a version of Myna[7].

Nice use of a tuning that doesn't get much attention (and usually as a mavila temperament when it does).

Essentially in the fourth scale you're tempering out 126/125, so it's a starling temperament of some kind. Keemun also fits your description, and it's simpler than myna. 7/6, 6/5, and 10/7 are mapped the same in keemun and myna, but 5/4 and 3/2 are more reasonably mapped for 23-edo.

Love the format and enjoyed the tunes. Thanks for putting
it together. -Carl

Hi Igs. I liked this a lot & shared it on Facebook, where a couple of musicians I know began asking about the instrumentation. What'd you play this on?

Hi MLV ("Major League Vaseball"?), thanks for the listen and share. My setup for that piece is just my little M-Audio Axiom 25 into Logic, using the EXS24 sampler plug-in. Super basic mildly cheezy fake guitar sounds have to hold me over until I get my 23-EDO axe from Ron Sword (hopefully by summer time).

Thanks for the listen!

You can call it whatever you like, just don't call it late for dinner!

If you want, I can retune it and upload just that part. I can imagine 27-EDO and 31-EDO working alright, although the 1-step melodic interval will probably all but disappear in 31. Alternatively, 15-EDO or 19-EDO might work just fine, since it's not a terribly harmonic piece. I know they're not Myna temperaments, but they fit the scale. Post a scala file of the tuning you'd like to hear and I'll let 'er rip.

Here's the file:

The difference is very mild to my ears. Maybe even placebo effect.

I can see a slight family resemblance to 23-EDO, but only in some areas. Some notes are right between two 23-EDO pitches.
