User:Inthar/Inthar's EDO impressions
(if i say meh, then that just means i havent messed with it enough or heard enough music in it)
5 - Equipentatonic.
7 - Equi-diatonic.
8 - Good edo if you like having 10:11:12:13-based harmony, only neutral second steps and no conventional consonances.
9 - Simplest and most extreme mavila tuning.
10 - The first conventional-sounding EDO in that it has both fifths and at least two sizes of seconds. The 7-note neutral third scale is cool.
11 - Supports some cool chords and scales. The widened seconds and thirds are a vibe in itself. Underrated.
12 - Not a bad tuning, all things considered.
13 - The 7- and 8-note pseudo-diatonic scales are good entry points for a beginner. Using the intervals which are similar to 12edo but have different moods requires balancing different tradeoffs.
14 - Intriguing and spicy tuning.
15 - Great tuning for simple but cool alternate-universe 5-limit temperaments such as porcupine and blackwood.
16 - Decent 5/4~16/13 and good 7/4. OK mavila tuning, but 41edo is better because of the harder but not too hard step ratio.
17 - Smallest edo that supports both the diatonic scale and (non-degenerate) 10-note neutral-third scales.
18 - The quintessential dual-fifth edo, with two fifths (667¢ and 733¢) that are almost equally off from 3/2. Supports the dual-fifth temperaments A-Team and sixix. It's the sixix tuning with the "worst" fifths but it still sounds fine; you just have to watch out for commas when viewing 18edo sixix as a dual-fifth temperament.
19 - The diatonic scale is useful for relaxing music; the Lydian especially shines. Also good for alternate-universe 5-limit comma pumps, and OK for semaphore.
20 - Meh.
21 - Interesting oneirotonic tuning (generator 8\21).
22 - Efficient 11-limit edo with features of 15edo, 17edo and 19edo. Some scales are good like superpyth and porcupine, others like pajara I don't like so much.
23 - The most interesting edo without a good fifth.
24 - Neutral-thirds edo with 12edo subset. Better semaphore than 19edo.
25 - Meh.
26 - Cool lydian. Also adds a perfect fifth and a 7/4 to 13edo's good approximations of 11/8 and 13/8; worth exploring for that reason alone.
27 - Great underexplored edo, with solid harmony and scales. Better than 19edo on the 18.104.22.168.13 subgroup. This is the point where rank-2 theory starts to be very insufficient for fully exploring the possibilities.
28 - Nothing interesting lower numbered edos don't have.
29 - Very cool diatonic scale.
30 - Meh.
31 - Meantone plus galaxy-brain enharmonic harmony.
32 - Like 27edo, with worse major seconds and thirds.
33 - Meh.
34 - 17EDO, but now there's a good third. The oneirotonic scale (generator 13\34) is very nice.
35 - Meh.
36 - 12EDO with 7th and 13th harmonics and phi.
41 - This and more accurate tunings are essentially JI.
