[edit] Magic temperament?

Theres some reference made in this page and on 22 equal temperament to a magic temperament. I would suggest that it's confusing and should be removed, since we don't even have an article on it to follow up on. Any objections? - Rainwarrior 04:37, 7 May 2006 (UTC)

I totally understand magic temperament and I could write an article on it but the problem is it would mostly be original research (well, not original to me, but thought up by members of the tuning list and not published in any peer-reviewed thing). I fear that's a problem with many articles related to tuning and temperament. —Keenan Pepper 04:53, 7 May 2006 (UTC)
Hmm. I'd say to go ahead with the article then. It at least wouldn't be out of place around here... but even if it's a scale no one's published, unless you think it's so obscure that it doesn't belong on wikipedia. If the source is the tuning list (...is that on Yahoo?) I guess you won't have much to link to, but you can at least explain its origins. My objection to its reference in this article is that there's no point in defining 19 temperament in terms of other things that aren't themselves worthy of an article on wikipedia. - Rainwarrior 05:03, 7 May 2006 (UTC)
Done. See if you can understand it and improve it. I'm looking for an example of a piece written in it, which I know exists because I've heard one before, but I can't seem to find any. —Keenan Pepper 05:46, 7 May 2006 (UTC)
The only thing I don't quite understand is the compatibility thing. Do you just mean that those EDO temperaments that have slightly-flat-from-just major thirds are considered magic-compatible? I might also mention that the term "tempers out" is something that has always bothered me a little. I haven't seen it anywhere except wikipedia, but in most of the uses I've seen it's not stated directly which interval is being tempered (traditionally, of course, it is only fifths that are tempered), and merely providing a comma's ratio doesn't really indicate how that ratio came about from the tuning system. "Tempers out", as I see it used on Wikipedia, is really only properly descriptive when you already know how the tuning system works. (What literature does the term appear in?) - Rainwarrior 18:27, 7 May 2006 (UTC)
This is what I mean by "compatible": The definining feature of Magic temperament is that five 5/4 "major thirds" exceed an octave by a 3/2 "perfect fifth". In 12-equal, this is not the case, because a major third is 4 steps, and 4*5 - 12 = 8, which is a minor sixth, not a perfect fifth, so 12-equal is not compatible with Magic. In 19 and 22, it is the case, so they are. It's not a strict definition because it depends on which approximations you use, for example 13-equal has two different approximations to 3/2 which are about equally bad, so it's not clear whether it's compatible or not, but it doesn't really matter because 13-equal is so bad anyway. Any "good" equal temperament will have a well-defined approximation to simple just intervals, so you can say whether it's compatible with a given linear temperament.
The practical meaning of all this is that if you have a piece written in Magic temperament, you can perform it in 19-equal or 22-equal, and the two will sound different but in both cases the harmony will work out. You definitely can't perform it in 12-equal, though. That's why I think compatibility is a good word to describe it. Meantone is compatible with 12, 19, and 31, so you can take something by Bach and play it in 19 or 31 and it sounds great, but if you try to play it in 22 you'll fail miserably, because it's incompatible. —Keenan Pepper 21:01, 7 May 2006 (UTC)
This is a good clarification, and explains that sort of usage of the term throughout the pages on tuning. (What, though, if the magic temperament is extended too far to be accomodated? Being a "linear temperament", isn't it infinitely extendable?). I might take a tour through the temperaments pages one of these days and try to replace or define these terms which seem to have become technical jargon. - Rainwarrior 22:17, 7 May 2006 (UTC)
