 ::: This is great news, is it the original one with the error or the fixed one? Anyway, I can now start working off my [[:Category:todo:add color name|todo list]]. --[[User:Xenwolf|Xenwolf]] ([[User talk:Xenwolf|talk]]) 22:52, 29 June 2021 (UTC)
+: Just now seeing this. (Feel free to message me on my Thank you Matt for finding this error and fixing it! I will update the page with the correct formulas.
+: I looked at your xen-calc, very nice! (Xenwolf, can we add this to the "Useful Tools" page?) I REALLY like your use of e.g. vM3\22. I will add that to the page on ups and downs notation.
+: But I don't consider y1 a valid name. I would call 80/81 a descending g1, not a y1. Same for z1, zg1 and sgg1. Considering all the possible 7-note segments of all the possible colors, half of them have no unisons, because the 8ves are less than 1200¢. Some don't even have 2nds, e.g. the central bizogu segment. An 8ve minus the 50/49 comma is a zzgg9 of 1165¢, and a zzgg2 would be a descending rryy-2. My reasoning is that intervals can be either ascending or descending, and also either positive or negative.
+: Ascending positive intervals (includes most ratios with N > D) go up in pitch, and either up the scale (e.g. 9/8 = w2) or stay the same (e.g. g1 or ry1 = 15/14)
+: Ascending negative intervals go up in pitch but down the scale, e.g. 50/49 = rryy-2
+: Descending positive intervals go down in pitch and either down the scale (e.g. 8/9 = desc. w2) or stay the same (e.g. 14/15 = desc. ry1)
+: Descending negative intervals go down in pitch but up the scale, e.g. 49/50 goes from ry4 "up" to the flatter zg5
+: Your broader use of the term negative to include descending is mathematically sound. 49/50 is a (positive) zzgg2. It also reduces (eliminates?) invalid color names, which is nice. But negative intervals are different than descending ones, and IMO it's nice to distinguish between them. They feel different. Descending intervals are commonplace and straightforward, but negative intervals only apply to certain JI commas. My narrower usage of negative functions as a warning that interval arithmetic works counter-intuitively. And the concept of descending intervals is well understood and doesn't require a new term like negative. So I think the narrower use of negative is better for pedagogical purposes.
+: Another objection: I see that xen-calc calls 4/5 a gu negative 3rd. Playing a note and adding a note 5/4 below it makes a yo harmony with a distinctly 5-over sound. If we call that interval a gu negative 3rd, that implies a 5-under sound. Sure, you can deduce from the term negative that the color is inverted, but that's extra mental work. I'd rather say the added note is a yo 3rd below the 1st note than a negative gu 3rd above it.
+: As I've said elsewhere, I'm the inventor of color notation, but I'm not a dictator. I welcome debate on this matter. :) --[[User:TallKite|TallKite]] ([[User talk:TallKite|talk]]) 09:36, 12 July 2021 (UTC)
