[edit] Too many redlinks
Generally, something should only be linked if it makes sense to write an article about it. What material could be used in an article on the septimal minor third? It's a good interval, even one of my favorites, but that doesn't mean it's worthy of its own article. —Keenan Pepper 05:06, 8 December 2005 (UTC)
[edit] Flip the ratios
As suggested, indeed we should flip all ratios. See for example in the article Interval (music). The ratios should have values over 1. For example a fifth is 3:2. It is more common to think in frequencies than in string or tube length. −Woodstone 21:34, 20 February 2007 (UTC)
- Makes sense to me, especially for the sake of consistency with the other article. Rigadoun (talk) 16:16, 21 February 2007 (UTC)

- Yes this is all backwards, if I am not mistaken. An octave being "twice" the pitch should be 2:1, and intervals between unison and octave should be between 1:1 and 2:1, no? Also, the interval 4:7 (apparently 7:4) is listed as the "seventh harmonic" -- but strictly speaking, isn't the seventh harmonic 7:1? I'm also wondering if 7:4 is also called the "harmonic seventh" (perhaps the words got reversed?), the "blues seventh", and/or the "barbershop seventh"? Pfly 06:51, 9 March 2007 (UTC)
- Well, it wasn't exactly wrong, as getting the intervals backwards just makes them descending instead of ascending, or in terms of string lengths and so forth, but having them greater than one is more common. Anyway, I've flipped them all for the sake of famiiliarity and consistency with most description. Yes, strictly speaking I suppose the seventh harmonic is 7:1, but it's more often thought of as being in the same octave as the nearby minor seventh (dividing by four just moves the pitch down two octaves). I'm not really sure abut the nomenclature, though. Rigadoun (talk) 18:07, 9 March 2007 (UTC)
- True, it wasn't wrong, although the cents would be negative :) ...thanks for flipping. As for 7:4, the Scala's list of pitches (which seems to be a widely used standard) calls it "harmonic seventh",[1], as does Mathieu's book "Harmonic Experience", as I read last night. So I think I'll flip the words. It appears that Harmonic seventh was once a page here, or at least there are some redlinks to it. A quick google seems to imply that there is some mild controversy about 7:4, but the sources I am most familiar with seem comfortable enough calling it "blue seventh" as well as "harmonic seventh". But perhaps "blue notes" are inherently not well defined. Thanks for the response! Pfly 18:50, 9 March 2007 (UTC)

[edit] Distance in semitones
I think it might be much more usefull if at least the musical intervals in the equal temperament would also include their width in semitones. —The preceding unsigned comment was added by 86.121.142.63 (talk) 13:29, 20 March 2007 (UTC).
- It's already there. The first column states the interval in cents. One hundred cent is a semitone. So where it says 500 cents, you can read 5 semitones. −Woodstone 15:02, 20 March 2007 (UTC)
[edit] Factorization column
In the table of intervals may be column named Factorization to indicate intervals of Just Intonations and its limit for them. If somebody have another opinion, please discuss. Commator (talk) 18:31, 13 December 2007 (UTC)
[edit] Unreferenced material
Intervals such as "ragisma" and "breedsma" need to referenced (dictionaries, texts, peer-reviewed journals). Frank Zamjatin (talk) 12:40, 15 April 2008 (UTC)
