No I wouldn't call "dominant sevenths" any kind of meantone since I don't consider anything with fifths wider than those of 12-ET to be meantone. But I note that "simple-7 kleismic" does far less violence to the 5-limit ratios of the parent 5-limit temperament than does "dominant sevenths". Your proposed system does have a precedent in the naming of rivers where, as you work your way up-river and you come to forks, the widest one gets to keep the name and the other is referred to as a tributary. But sometimes it's a tough call. What would correspond to tributary wideness here? Shouldn't it be some kind of badness measure (combining error and complexity, rather than just error as you and Paul seem to be proposing)? You know me. I like systems. And since you're proposing a system here, I'll be happy. Meyers-Briggs personality type INTP = "the architect". :-) When there is no system to the naming, the name just becomes one more thing you have to memorise (or look up every time), rather than an aid to memory.

I hadn't intended any meaning for the "2" from February. "Hitchcock", although named in reference to the 39-step MOS, does have a smaller 32-step MOS with full 13-limit hexads, but my program was set to ignore scales with large steps more than 3 times the size of the small steps (which tend to be less useful musically), so I didn't notice it.

Message: 11163 - Contents - Hide Contents Date: Wed, 30 Jun 2004 18:36:38 Subject: Leapday From: Gene Ward Smith This is the 13-limit temperament with wedgie <<1 21 15 11 8 31 21 14 9 -24 -47 -59 -21 -33 -13|| and mapping to primes [<1 2 11 9 8 7|, <0 -1 -21 -15 -11 -8|] The generator is a fourth or fifth, and if we want the completem temperament, including fives, then in terms of equal temperaments there is not a lot of point in tuning it to anything but 46; 27/46 is a poptimal generator, and the next one I found was 254/615; hence leapday is firmly wedded to 46. The TM basis is {91/90, 121/120, 169/168, 352/351}, compatible as we have seen with HTT. The no-fives version of leapday has a TM basis {169/168, 352/351, 364/363}, which adds 169/168 to the commas of HTT. It has a different TOP tuning, and we may want to use the 63-equal tuning in place of 46 equal if we have no interest in 5, because this gives better results for the other primes excepting 3, and is close to the no-fives rms optimal value. We have MOS of size 17 and 29, and a white-black analysis gives the 46 equal tuning as 29+17; the 63 equal tuning has a white-black of 46+17. Here's a comparison of 46 and 63, using 21/63 = 400 cents in place of 20/63. 46 vs 63 sharpness of primes 3: 2.39 2.81 5: 4.99 13.67 7: -3.61 2.60 11: -3.49 1.06 13: -5.75 -2.43 ________________________________________________________________________ ________________________________________________________________________ ------------------------------------------------------------------------ Yahoo!

Message: 11165 - Contents - Hide Contents Date: Thu, 01 Jul 2004 00:58:31 Subject: Simultaneous temperament approximation From: Gene Ward Smith If we have several temperaments we want to approximate, we can treat it as a modified multiple diophantine approximation problem, modified since we step through the lcm of the periods. Hence, to approximate meantone and pajara simultaneously, we look for even numbers n which give a good simultaneous approximation to both fifths. Below I give the maximum relative error, with the rms tuning treated as optimal, times the square root of n, where 2n is the approximating et; and list solutions under 1000 with this badness figure less than 0.6. We can, of course, do this for more temperaments than just two. We've discussed 198, and Paul mentioned 88. That 12 should be good is of course obvious. 12 .215906 -.033520 .088143 88 .580526 .087518 -.020282 100 .479848 .053997 .067861 198 .528192 -.053085 -.045636 298 .271293 .000912 .022225

I did discuss it fairly extensively when I first introduced the wedge product, if I recall correctly, in connection with the commutator.

As a consequence, you get a {3,5} version of the 7-limit which is wafso-just if I recall correctly what that means. In place of 2, you would use (27/25)^9, and in the place of 7, (3^17/5^11)^2. While ennealimmal is accurate enough that this will work, it isn't a very good tuning, relatively speaking, and you can do much better by using a tempered 3 and 5.

Maybe upload it, or post it if it is postable. I suppose I should get an alternative email address.
Message: 11171 - Contents - Hide Contents Date: Thu, 01 Jul 2004 23:25:48 Subject: Extending temperaments using TOP tuning From: Gene Ward Smith I havn't made use of the "brute force" approach Dave and Herman have had success with as a temperament finding algorithm, being an algebraist by training. However, it occurs to me that if I want to find higher limit tunings which accord with a lower-limit tuning and hence deserve the same name, I could as an alternative to my algebraic approach simply use the TOP tuned generators and search for good approximations to the higher-limit primes. If I use the 5-limit TOP values for 2 and 3, and if I search for exponents for each in the range -100 to 100, I get only one value within 2 cents for 7, namely 3^10/2^13 (leading to 7-limit meantone), and only one value for 11 within 2 cents, 2^24/3^13, leading to 11-limit meantone, or "meanpop". I find nothing for 13 under 2 cents, and it hardly makes sense to increase the range of the exponents past a complexity of 100. Pushing the error limit up to 9 cents gives 3^46/2^69, which isn't going to break any records for wonderfulness. The wedgie for this 13-limit meantone is <<1 4 10 -13 46 4 13 -24 69 12 -44 92 -71 92 207|| The mapping is [<1 2 4 7 -2 23|, <0 -1 -4 -10 13 -46|] The TM basis is {81/80, 126/125, 385/384, 1573/1568} The TOP generators are only slightly different. 112 equal is one tuning choice, but the temperament really makes no sense, since you may as well simply use 31.

(Be sure to send a copy of it with the paper.) Augmented should be [7 0 -3> in the table at the end. The mathematical parts looked easy enough to understand -- some of it seemed a little too obvious to me, but for the average reader who hasn't been following the tuning-math list it would be more of a challenge. A whole paper could be written just on the musical applications of wedgies, so it's probably just as well that they're not mentioned. But you should at least have some description of what a "bivector" is if you're going to include them in the tables. A couple of brief notated musical examples would be nice, like a typical octatonic chord progression you might find in 12-ET music to illustrate the 648;625 comma (the A minor - C minor - Eb minor - F# minor cycle on my diminished temperament page for instance).
