This extends to the 7-limit system 5120/5103^4375/4374 =
[5,13,-17,-76,41,9], with a 28/99 generator. This could be called "amt" also, unless someone has a better idea for a name--which probably would not be hard.

How about "quarter major thirds"?

I've called it "quarter fourths" in the past, but it could also be
"third of major thirds".

I can certainly live without those 4 beyond pelogic, i.e. hemithird
and the three new unnamed ones (which can probably remain unnamed). So
that would leave 19.

How was the name amt arrived at. Is it an abbreviation for something?
It could be called "fifth of eleventh".

It's an acronym for "acute minor third", from its generator.

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

I think quadrafourths would be fine.

Lets call it that then, since AMT isn't pronouncable and why save one
syllable just to make it more obscure.

I'm happy with both of those. The only worry: there are lots of things
called chromas in Manuel's intnam.par. Would "chromatic" be better, or
would that tend to suggest something else?

so 7625597484987:7629394531250 would be the first major one we're
cutting off? it's of course important as the 5-limit aspect of
ennealimmal. you might argue that ennealimmal is a higher-limit
consideration. but will the current criteria dave is using preclude
its inclusion when we get to higher limits? i certainly hope not. we
don't want to go through this same subjective process over again for
every 'limit'.

This is about 2/3 of a whole tone, in Latin "bes toni".
So how about bestonic?

When I came up with "chromic", I thought of certain compounds of chromium, such as chromic acid. I suppose we could just call the thing "chrome".

16875/16384, right? "best tonic" -- 16384 is a power of 2 . . .
hmm . . .

sounds like 'bastoni' (italian bread). fits in well with 'injera'
(ethiopian bread). actually this works well, since 225/224^49/48
(bastoni) is in the same 'aisle' as 81/80^50/49 (injera).

Amt sure is pronouncable. I must say I'm quite amt about the keeping
the name. :)

Actually, I don't care what you call it.

Except "acute minor thirds". That's a terrible name:

1. Three words. Temperaments should have cool, single-word
names.

2. I find it perverse to name temperaments by their relation to
diatonic intervals. I guess this counts against Amt too.

Well yeah, but if possible, they should give you some clue as to what
the temperament is. This can be

(a) The size of the generator (and possibly how many periods to the
octave when there is more than one):

neutral thirds
acute minor thirds
hemithirds
quadrafourths/bestonic
chrome
augmented (indirectly)
diminished (indirectly)
pelogic (indirectly)
orwell (obscurely)

and possibly semisuper if "semi" is meant to indicate the half-octave
period and "super" is short for super fourth. However I don't think
most people distinguish between semi and hemi, so I think "twin" (or
"double") is a better indicator of a half-octave period, as in "twin
chains", which generalises to triple, quadruple, quintuple, sextuple,
septuple, octuple, ?...

Also note that in lowest terms the generator for "semisuper" is in
fact a better example of a chromatic semitone than the one for
"chrome".

or
(b)The comma that vanishes:
schismic
kleismic
diaschismic
wuerschmidt
tiny diesic
minimal diesic
limmal
meantone (indirectly)

or is "meantone" indicating the generator size indirectly?

Unfortunately this method doesn't generalise well to higher limits
since more than one comma vanishes. We could stick to using the single
comma that vanishes in its 5-limit subset, but that won't work for
temperaments that don't _have_ a 5-limit subset.

A problem with having these two different systems is that when the
comma is bigger than a chromatic semitone (71c) or the generator is
smaller than a large limma (133 c) it isn't clear whether the name
refers to the generator or the comma. limmal and chrome being
examples.

(c) No clue whatsoever:
porcupine
starling
pajara
magic
miracle

There's nothing particularly magical or miraculuos about Magic and
Miracle at the 5-limit.

I can't see any reason to stop calling neutral thirds by a two word
three syllable name. I think number of syllable is more relevant than
number of words. I think 2 words is ok if no more than 4 syllables.
di-a-schis-mic, par-a-kleis-mic, sem-i-su-per. And a-cute mi-nor
thirds isn't as bad as min-i-mal di-es-ic.

I know what you mean, but it's not too perverse for 5-limit since the
JI diatonic is 5-limit. But hey, that's simply how we name intervals,
of any limit. I think we're stuck with it.

I favour naming temperaments based on the size of the generator and
the number of periods to the octave. That immediately tells someone
how to make a scale from it with only basic math.

I favour describing the size of the generator as the appropriate
fraction of the interval (within the specified limit) that needs the
fewest generators and only whole octaves, provided it is accurate
enough and provided it can be done in four syllables or less. This is
more-or-less the approach Gene used with:

hemithirds
quadrafourths (except this should be trithirds, my mistake)

Using this system, AMT becomes

pentelevenths

I'm unsure whether we should put an "s" on the end or not. But I think
we should, because "neutral third temperament" sounds odd to me.

Porcupine would become hemiminorthirds. Too many syllables. We could
shorten it to haemorrhoids. No? OK, I guess it stays porcupine. :-)

Chrome would be quadraminorthirds. Too many syllables again. Is there
a shorter way to say "a quarter of"? Is there a shorter way to say
"minor thirds"? There _is_ a shorter way to say "half of", "bi" as in
bicarbonate.

Tiny diesic becomes hemisixths.
Minimal diesic becomes quadrafifths.
4294967296/4271484375 becomes septathirds.

Any valid generator could be used, not just the smallest one.
So semisuper becomes twin tritenths or double tritenths.

But it's no use calling pajara/twintone/paultone "twin fourths" or
"twin fifths", since that could apply to twin meantone as well.

And Magic and Wuerschmidt would both be "major thirds" so they had
better stay as they are.

There's not enough variety in this naming scheme for my taste. In

Does anyone have a list of the proper latin-derived prefixes for the
various fractions.

And shouldn't we use "semi" for 1/2 since we already have semitone.
And hemi is greek, not latin, as are tetra, penta, hexa, hepta, (octa
is both L and Gr). And please ignore my suggestion of "bi", it
cleraly means 2, not 1/2.

Similarly I realise we can't use "tri" to mean 1/3 since it already
clearly means 3 in tritone. Is "tertia" clearly 1/3 and not 3?

Do any of them beyond 2 clearly mean 1/n and not also n?

I think "quarta" is more clearly 1/4 than "quadra" which sounds to me
like it could equally mean 4.

Is "quinta" clearly 1/5 and not 5?

Or is it the case that you change them from a multiple to a fraction
by changing the final vowel e.g.

semi
terti
quarti
quinti
sexti
septi
octi

Even if there's no such rule, we can make one, it's pretty suggestive,
following on from semi.

Certainly a quartile and a quintile are 1/4 and 1/5. I could only find
that a tertian is 1/3 of a tun (liquid measure). And a sextary is 1/6
of a congius or modius. And there's sextant meaning 1/6 part.

So we have the following:
semiminorthirds (porcupine)
tertiminorsixths (orwell)
semisixths (tiny diesic)
quintelevenths (AMT)
quartififths (minimal diesic)
tertithirds (quadrafourths)
twin tertitenths (semisuper)
septithirds (4294967296/4271484375)
quartiminorthirds (chrome)
semithirds (hemithirds) [not on my list for the paper]

The only prefix I'm not real keen on there is "terti", maybe 'cause it
sounds like "dirty". Other suggestions?

I think some of these systematic names sound pretty crazy and if any
of them had had any history I thing you'd remember them just fine. I
been remembering several temperaments just fine up till now, simply by
the generator size in cents. I just say to myself "oh that's 126 cent
temperament" or whatever. Orwell was "272 cent temperament" or
"subminor thirds temperament" to me for a long time.

That's your problem. I long ago ceased to think of them as in any way
related to the diatonic scale, they are just particular sized
intervals near particular ratios.

I thought you said you'd rather know the comma. The generators are, as
my most recent name suggestions approximately tell you,
semithirds, half a major third, 193 c, (rms is 193 c)
tertithirds, a third of a third, 129 c, (rms is 126 c)
quartiminorthirds, a quarter of a minor third, 79c, (rms is 78 c)

Oh yeah. If folks were told once that it was a 19/84 oct
generator, I'll bet some would come back to it months later wondering
"was that a temperament consistent with both 19-tET and 84-tET".

Nah they're both half. Hemi is greek semi is latin. We need latin,
since semi is already used for exactly the purpose I want to use it,
in semi-tone.

Indeed. I think gene made up the "tiny diesis" to start with. But if I
say semisixths and quartififths anyone who knows the system (and
even the system is not too hard to figure out for yourself) can figure
out the rest if they want to.

Very few musicians and composers even know the difference between a
pythagorean and a syntonic comma, let alone what a diaschisma or a
kleisma is. The historical comma-based names can stay but I say we
don't base any more on obscurely named commas.

In contrast, everyone knows what thirds fourths etc. are, even if they
will assume the 12-tET version instead of the just.

They are fun when you're in the in-crowd who knows, but they are

But Carl, that's only because it has a history with you.

There is at least one temperament name that essentially uses this
system that has been around for a long time. I'm sure you don't have
any problem recognising it. neutral thirds.

Sure the terti quarti quinti ones are a little more difficult but they
will usually be the more complex and therefore less popular ones
anyway. When we go to higher limits, the best ones often have a
generator which is a whole consonant interval. Like "subminor thirds
temperament", the name that was used before "Orwell", for that 7-limit
temperament.

That doesn't really work in any exact way, and it incorrectly leaves the impression that temperaments are octave-based; if you want to really be scientific about it I suggest thinking of them in terms of the wedgies. To me wedgies do the precise naming thing, and verbal labels do the "remember this" thing.

It refers to 3125/2304, which I claimed was a semisuper fourth for the purpose of coming up with a name for the temperament. This, by the way, shows why I prefer "hemi" to mean "half"--"semi" is much more vague.

One thing they might help with is with this idea that things are octave-based. If 81/80 defines meantone, where's the octave?

I've added proposed systematic names to my spreadsheet now, for all

they were only invented yesterday.

There would be no harm in giving more than one name for each

This has been full-on addictive for me the past few days. You'll all

Carl, I believe I have provided the "crucial BS control" that you were
hoping for.

I hope that by the time I come back you will all have long-ago agreed
on the final list for 5-limit and moved on to 7-limit. I suggest doing
that before coming back to the incomplete ones, for the same reason we
did 5-limit first; we're familiar with it.

I mean more than that. My point of departure is that for example 5-limit meantone is defined by 81/80. I now decide to look at this in connection with octaves, and take 2/\81/80 = [0,1,4], giving me my map to generators. Then [0,1,4]/\[a,b,c] = 2^(c-4b) 3^4a 5^-a so if a=1, b=1, and c=0 I get [0,1,4]/\[1,1,0] = 81/80. This may therefore be used as a map, giving me generators of an octave and meantone fifth.

What if I look at 720 instead of 2? I now have 720/\81/80 = [-6,0,24].
This has a gcd of 6, so I divide out the 6, getting [-1,0,4]. I now wedge [-1,0,4]/\[a,b,c] = 2^(-b) 3^(4a+c) 5^(-b), so a=b=1, c=0 will work to give me 81/80: [-1,0,4]/\[1,1,0] = 81/80. I now use this as my map, setting the condition that 720 must be pure if I want. I get generators of about 3/2 and 3, and if 720 is pure, then the 3 is really 720^(1/6), and is my period, and the meantone fifth is my generator. Now meantone consists of six parallel lines of generators an approximate twelvth apart!

My point is, meantone is not really defined by the choice to priviledge octaves, which is a separate consideration.

You'll have to do better than that.

270.8 cent generator, [-2, -3, -1] mapping, 45 cent minimum MA error

The generator here must function as 7:8, 6:7 and 5:6. Look at the
minimum error. As a 7-limit temperament it is garbage. But if forced
to find a meaningful name for it I would call it "7:8 = 5:6" or
"supermajor second minor thirds" or "diminished third minor thirds",
after Gene's naming of "fourth thirds".

271.3 cent generator, [7, -3, 8] mapping, 4.5 cent minimum MA error

This is of course 7-limit subminor thirds or 7-limit orwell.

I must point out that Gene invented the "generator as fraction of
consonant interval" nomenclature, with "quadrafourths". I'm just
arguing that we should
(a) extend its use,
(b) refine the prefixes to more clearly indicate fractions as opposed
to multiples,
(c) use latin consistently (not mix it with greek), and
(d) apply it always to the interval that is made up of the fewest
generators (and doesn't contain any periods except as whole octaves).

Regardsing (c), I wouldn't mind if they were consistently greek except
I feel the latin ones work better regarding criterion (b) (fractions
versus multiples).

Regarding (d): In the case where there is more than one consonant
interval which is made up of the minimum number of generators, then
the largest and smallest in size should both be mentioned, as above.
This was Gene's invention too, with fourth thirds.

I also think that when a temperament _does_ extend to being good at a
higher limit, fewer generators map to a consonant interval at the
higher limit, then it fine to use the higher limit name prefixed by
the limit. So 5-limit Orwell can also be called 5-limit subminor
thirds and we can forget about calling it tertiminorsixths.

Kleismic and parakleismic is a better example of the problem you were
setting up for me. I approve of these names, and para (presumably
meaning "near to") might generally be used for the badder of the two
since para can also mean "improper".

So the horrible 270.8 cent temperament above could also be para-orwell
or para-subminor-thirds.

However I remember Gene using cata- meaning "down". Its opposite is
ana- (up). I quite like these two, and they (or para) would remove the
temptation to use semi to mean "almost", and leave it to mean "half",
as in semitone or semicircle.

So the horrible 270.8 cent temperament above could also be cata-orwell
or cata-subminor-thirds. And parakleismic could be catakleismic.

Gene, What was it that you used cata- for?

It had a generator in the 7 and 11 limit a whisker below the
kleismic 5-limit generator, but I really shouldn't have called it that, since it is a whisker *above* the h19^h15 = [6,5,3,-7,12,-6]
7-limit generator, which I was taking to be the 7-limit kleismic.
So it's a misnomer. The other reason is that it sounds like
"cataclysmic"--ha ha. Get it? I don't either. :)

It's referred to as "Starling temperament" on the Warped Canon page,
although of course the canon doesn't take advantage of the 7-limit commas
in this case. I believe I also referred to it as a temperament in some old
posts to the tuning list. I described it as essentially what we'd now call
a planar temperament with (approximate) major third and minor third
generators, having 126/125 as a unison vector. This would have been
sometime in 1999, but I don't have the exact reference.

The prototypical Starling scale had a 312 cent minor third and a 388 cent
major third. A later variation had slightly tempered octaves. But I'm
starting to think that the exact size of the thirds isn't the most
definitive feature of the tuning. Those were just the sizes of the
geenrators that optimized a particular set of 7-limit intervals I was
interested in at the time.

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.

wouldn't this be a *tempering of* starling? i thought that starling
was the *planar* temperament defined by *only* 126/125 vanishing;
this here is one *linear* temperament of that (1029/1024 vanishing as
well), with a 'fifth' of 702 cents, and a 'major third' of 390 cents.
this generator would imply that the most important scales have 15,
16, 31, 46, 77 . . . notes per octave. is this really starling?

This is the one you suggested calling chrome. Starling? No. As Paul
said, its only one possible further tempering of the real Starling
planar temperament. But also it's a very uninteresting temperament,
having so many generators to the fifth, with errors still as large as
3 cents. With a smallest MOS of 15 notes (having one triad) it's also
fairly uninteresting melodically. It's marginally more interesting at
7-limit, but beyond that forget it.

Quarter minor thirds is a good enough name for it for me.
