User:IlL/Inthar's primodality impressions

My impressions of Zhea Erose's prime families (the lower ones, anyway). Subject to updates as I familiarize myself more with them.

  • /2: Its raw power does have its place but it's surprisingly monotonous (especially without modulations).
  • /3: More interesting than /2; 6:7:9:11:13, 9:11:13:15:17 or subsets thereof are good basic harmonic units. /3 can be used to contrast with /2 chords in temperaments that are noticeably not JI.
  • /5 (overtones 10-20, no 16): still kinda blending and somewhat familiar due to 5 limit major and minor triads and some leading tones. Most sticking out are the 11/10, 13/10, and the sharp 19/10 major seventh which I love.
  • /7 (overtones 14 to 28, no 16): I find myself sliding up chords and seeing them deform. More complex identities let you transition between the simpler ones like: 17-19-21-23 (complex); 9-10-11-12 (simple); 19-21-23-25 (complex); 10-11-12-13 (simple). The fifth (14-21) helps you appreciate the complexity of 17-19-21-23-25 by itself. The 21/20 and 22/21 are also nice to have, and help bridge the lower and higher complexity parts of the scale.
  • /11 (overtones 11 to 22, add 33): Neogothic major and minor thirds. Lots of neutral-ish and quasi-24edo intervals; somewhat 17edo-y too. The weirdest parts for me are the 15/11, 17/11 and 19/11.
  • /13 (overtones 13 to 26, add 39): Feels somewhat like a chameleon of 19edo, 13edo and 17edo; it has the 19edo minor second and godzilla third, and then you have the 13edo-like 17/13 and a succession of 12edo-to-13edo-sized steps in the middle, and then you have 17edo-sized sevenths.
  • /17: 1st octave looks like 13edo-16edo-18edo-22edo. Has believable approximations of some Father octatonic scales.
  • /19: Just eyeballing: The notes are already changing way too fast for a good coarse edo description. I'll have to stop here, except to note that some things here look good for basing a 14neji on (might be better than 13neji).
