This looks like a good candidate for the "Starling" name. Besides having 126/125 as a unison vector, its generator is a prominent melodic interval in Starling temperament.

I used to spell it that way, but quit because everyone seemed to spell it differently. Still use "sk" to mean 2^(1/612), though. how do you
> pronounce "schism"? like "shism"? naah . . .
Usage Note: The word schism, which was originally spelled scisme in English, is traditionally pronounced (szm). However, in the 16th century the word was respelled with an initial sch in order to conform to its Latin and Greek forms. From this spelling arose the pronunciation (skzm). Long regarded as incorrect, it became so common in both British and American English that it gained acceptability as a standard variant. Evidence indicates, however, that it is now the preferred pronunciation, at least in American English. In a recent survey 61 percent of the Usage Panel indicated that they use (skzm), while 31 percent said they use (szm). A smaller number, 8 percent, preferred a third pronunciation, (shzm). In the ethnic bread department, the closest I can come to "chromic" seems to be "chimichurri", an Argentine bread. Other great names abound--lavosh, focaccia, ekmek, hapanleipa, panatone and malasadas.

I followed that conversation and, although I have strong convictions about what was discussed, I just didn't have the time to get involved in it. My thoughts on this are: 1) Johnny is already very familiar with cents, so that is what works for him. For the rest of us it would take a bit of training to be able to do the same, and then might we need a calculator to determine the intervals? When you are writing chords, where do all the cents numbers go, and how can you read something like that with any fluency? (But that is for instruments of fixed pitch, which do not require cents, which brings us to the next point.) 2) Tablatures were mentioned in connection with instruments of fixed pitch, where cents would be inappropriate. I hate tablatures with a vengeance! Each instrument might have a different notation, and this makes analysis of a score very difficult. We need a notation that enables us to understand the pitches and intervals, regardless of what sort of instrument is used. 3) Gene mentioned that we are most comfortable with whatever is the most familiar, but a multi-EDO/JI notation such as we are trying to achieve is going to have something new to learn, no matter what. It's best to make it as simple and logical as possible, and in my opinion this is best accomplished by symbols that correspond simply and directly to tones in each system, maintaining commonality across those systems as much as possible. Whether the maximum symbols per note should be one or two is something that still needs to be resolved, but I think that we should develop both approaches and see what results. Once that is done, then we can evaluate each, pro and con. As long as microtonality is such a niche market, I think that this is one extravagance that we can afford.

The comma is 4095:4096 (~0.423 cents). (Has anyone previously found it and given it a name?) Multiplying 81/80 by 64/63 gives 36/35 (~48.770 cents), which comes very close to 1053/1024 (~48.348 cents), the ratio which is to define the 13 factor. This very small comma vanishes in ET's 12, 17, 22, 24, 31, 34, 36, 39, 41, 43, 46, 53, 94, 96, 130, 140, 152, 171, 181, 183, 193, 207, 217, 224, 270, 311, 364, 388, 400, 494, 525, 581, 612, and 742. It does not vanish in 19, 27, 50, 58, 72, 149, 159, or 198, and this seems to be due to inconsistencies in those ET's. For those systems under 100 in which it does not vanish, I don't think that ratios of 13 will be used to define their notation, so this should not be a problem.

Or given these choices, (a) one and a half, less an eighth, or (b) one and three eighths, or (c) three, less one-fourth? The particular intervals that were mentioned (farther above) in connection with this issue are ratios of 11 and 13 that I like to think of as semi- and sesqui-sharps/flats. Making these the large units of notation (according to the number of stems in the symbol) rather than full sharps and flats makes the reading of these ratios much simpler and solves the problem of having to decide whether to notate a half-sharp/flat or a sharp/flat less a half. In effect, by halving the units I have turned the halves into wholes, which makes available choice (c) above, which, in addition to being at least as simple as choice (a), does not combine an up with a down. (As to how I make the distinction between ratios such as 11/9, 39/32, and 16/13, you will have to wait a while to see; at present I have two different methods.) Anyway, when in doubt I think it will come down to trying it both ways in order to see what looks better. I mentioned that my latest approach has two variations, and if I can't determine a clear choice of one over the other, then I will be presenting both so that we can decide which is better. --George

When was it decided these temperaments were "far harder for the ear to understand"? Even if so, augmented is more complex than meantone if you measure by the simplest MOS to contain a consonant chord (8 compared to 5 notes). Still, for whatever reason you want to privilege fifths. The rule you give, generalized to higher limits, will favour simpler ratios in general. That'll give the usual bias towards temperaments that work with the limit lower than the one you asked for. And it'll miss temperaments where a simple interval is close enough to use in modulations, but isn't the defined approximation to 3:2. Graham

That was before I went back to using Paul's weighted complexity. Now it comes out badder than pelogic and semisuper (and with my new parameters 5.5c and 0.43 power, badder than seventh of major third [-9,7] and parakleismic).

Being good at 7-limit is a good reason to have a name for it, but obviously should have no bearing on whether or not it's included in the 5-limit list. If you modify your badness to use log-of-odd-limit weighted complexity you will see that its requirement of 9 generators to the fifth combined with its so-so 3 cent rms error, gives it a badness of 1113 that pushes it way down the list. The worst on my proposed list so far is only 625 by this badness (quadrafourths). But I don't mind including it so long as it doesn't require you to include anything else. By your badness with weighted complexity, there may well be some others in between quadrafourths and "chrome" that I will find objectionable. There are certainly some that _you_ will find objectionable: the half and twin neutral thirds and kleismics (that I'm happy to omit).

Not accurate; I think "chromic" would be a good name, since the generator is 21/20~25/24, the chromatic semitone or chroma.

There shouldn't be anything special about 1.3.5 and 1.3.7 compared to 1.3.7:5 as defining chords. So far my script only works with the former, but don't make any plans assuming that will always be the case. It should even be possible to automatically find and evaluate the simplest subset if that's all you want. Graham

Paul, don't you mean "divided by". log(3) is smaller than log(5) so if you want to favour fifths ... Here's the formula I'm using: SQRT(((gens(1:3)/LN(3))^2+(gens(1:5)/LN(5))^2+(gens(3:5)/LN(5))^2)/(1/ LN(3)^2+1/LN(5)^2+1/LN(5)^2))*1200/period_in_cents

carl, if 'identity' is defined as 'consonant interval', then the *only* thing going in here is the individual gens per identity. that's all. E13-F13 is the major sixth or minor third.

I have no idea what torsion is, but of course this is not simply meantone. It has a half-octave period. And thanks to Graham's list I've corrected its (lowest-terms) generator now to 96.2 cents.
>> 81/80 half meantone-fifth [0,2,8] [1,2,4] 348.1 1200 >> 81/80 half meantone-fourth [0,-2,-8] [1,2,4] 251.9 1200 >

This assumes the reader is a mathematician. Are we planning to publish this in a math journal or a music journal? I don't see a problem with listing them in the appropriate place in the list, based on their complexity. I don't see how you can disqualify them as 5-limit temperaments simply because all the 5-limit intervals are approximated by an even number of generators. What kind of a definition of temperament would disallow that? Isn't a (octave-equivanlent) 5-limit temperament simply any scale or tuning system that approximates ratios of 1,3 and 5 and their octave equivalents? There can be no argument that they are not _linear_. They have a single generator operating withing a whole-number fraction of an octave. I think, Paul, that maybe you're being blinded by your "hypothesis", since here we have the same comma involved in different temperaments with different complexities. How about you modify your hypothesis to take care of that, rather than try to deny that these are temperaments. And lest you are tempted to now claim as Gene has, that these are simply meantone, I claim that a temperament is fundamentally defined by its mapping of generators and periods to primes (with generator and period in lowest terms), not by the commas that vanish. different mapping = different temperament. Seems obvious enough to me. If your algorithm fails to find certain kinds of temperament that other algorithms do find, you shouldn't try to deny their existence, you should fix your algorithm.

Oh dear I keep doing that don't I. Must be the Alzheimer's. :-)

Well, crazy names won't tell you as much, but are more memorable, and might make up for it. See also my complaint about using diatonic intervals for temperaments where the diatonic scale may not even be supported.

I still don't know the generators for these.

Where historical names exist, I think they should be used.

But you'll never forget it once you've heard it.

I'm not sure I do. I'd guess semi is partial, while hemi is exactly half. Super is short for super fourth?
>(b)The comma that vanishes: >schismic >kleismic >diaschismic >wuerschmidt >tiny diesic >minimal diesic >limmal >meantone (indirectly)
These are my favs -- I consider unison vectors far more informative than generator size. Except for stuff like "tiny" diesic vs. "minimal" diesic, which I still don't know as I write this.
>or is "meantone" indicating the generator size indirectly?
Meantone is just historical. It doesn't have to make sense.

I was just going to mention that.

Indeed. That's when we resort to shamelessly locking in all of our surnames! :)

That's okay. These names are historical now, too.

I don't think any established (as in, more than a month or two) names should be changed at all.

I don't care if it's hard to say, I just want people to want to say it. Compare "Acute minor thirds" to "kleismic" here. Characters from novels, breads, etc., are also good.

I'm willing to accept this, but I don't have to like it. I try to avoid it, at any rate.

There's not enough variety in this naming scheme for my taste. In effect, I'm going to have to think about the name each time I hear the temperament, whereas "orwell" lives in my mind as its own entity. -Carl
