Subject: I get the message!

From: Dave Keenan

I guess I'm a bit slow on the uptake, but I think I'm getting the
message now, from both Gene and Carl. If I may be allowed a little
exaggeration:

Dave, we don't want to know about any systematic naming schemes for
temperaments or commas. Stop spoiling our fun. We were having a fine
time making up silly names for everything we could churn out, until
you turned up.

Well, I shall go and leave you in peace.

Peer review? More like peer insult-exchange.

Gene,

I apologise again for the personal insult.

You said you did not call me names, and that's technically true.

However I pride myself on my teaching and writing ability (perhaps
mistakenly) as well as my system design ability, and so I'm afraid I
do take it as a personal insult when someone who hasn't even read my
article makes assumptions about what my method of exposition will be
and declares them "sloppy", using the word three times, no less.

You also said I was "going about it in a very, very bad way", and
implied that my readers would need a "secret decoder ring" to
understand my article. All without having read any of it.

Yahoo groups: /tuning-math/message/7236 * [with cont.] 

I hope you can now understand why I found all this far more hurtful
even than being called an anal retentive. 

But even if I felt insulted, I should not have responded in kind. I'm
sorry.

By the way, you probably don't realise that before you arrived,
practically _all_ the prime-exponent vectors we used were 2-free, and
no one had a problem with that.

Paul,

I certainly don't want you to use letters instead of names in those
wonderful diagrams. I'm just saying I think it has gone far enough,
and besides there is at least _some_ kind of logic to most of those names.

Regards,
-- Dave Keenan

Subject: huge list of 11-limit intervals

From: monz

spurred on by the work i did on Dave's list of "kommas",
i've made a huge list of all the 11-limit intervals where
the <3, 5, 7, 11>-monzo exponents are 
<-15...+15, -10...+10, -4...+4, -2...+2>, arranged in
order by cents.

it takes quite a while to download ... there are over
28,000 intervals in the list.  i hope it will be very
useful as a reference.

this looks important to me, and i want to understand it.
can you help, by labeling these lists of numbers?

in this example, i think i recognize [0, -2, -3, -2] as 
a monzo, but it doesn't make sense as a [2, 3, 5, 7]-monzo.

and is [1/9, 1/24] meant to represent 2^(1/9) and 2^(1/24)?
if not, then what?

and what about [9, 15, 22, 26]?  what's that?


Gene, it would help me a lot if you would *always* put
a brief legend before lists like this.  pretty please?

ah, thanks for mentioning a third important example!

the software retains the data for 2, but the default 
in *displaying* the data to the user is to start the 
prime-series with 3.

if the user wants to see the data for 2, that option 
is available.  

for that matter, if the user wants to see ratios, 
that's available too.

the default notation right now is what we're calling
"prime ratios".  for example, the 15/8 ratio is displayed
by default as 3^1  5^1 / 2^3 ... well, that's the best
i can do in ASCII equivalent, but the software uses
actual superscripts instead of carets, and puts the
numerator and denominator on separate lines with the
separator line running horizontally.

i hope to be able to get regular monzo notation, i.e.
where 15/8 would be [-3 1 1], as soon as possible ...
but it will entail a lot of work with the graphics,
so the first release will probably not have it.  i'm
disappointed about that, but my partner does the 
coding and he has a much larger role than i in 
determining the priorities on the coding work.

it's the same thing that's shown in the linear temperament table on 
your et dictionary page -- the mapping from generators to primes. so 
for example, the third entry in each of the vectors, 22 and -3 
respectively, refer to the fact that the third prime, 7, is 
approximated in the temperament by stacking 22 of the first generator 
(otherwise known as the period) and -3 of the second generator 
(otherwise known as, simply, the generator).

> and is [1/9, 1/24] meant to represent 2^(1/9) and 2^(1/24)?

yes.

thanks ... mainly because i'm not even sure *how* to search

hi monz, i found this:

Yahoo groups: /tuning-math/message/3151 * [with cont.] 

but for some of the ETs you're asking about (namely the ones 
inconsistent in the relevant limit), gene is going to assume the 
standard val, even when better vals are available . . . to get 
an "untainted" answer, you should provide a list of vals, not merely 
a list of ETs.

hi Gene,


have you already posted the TM-reduced bases for a number
of common ETs in various prime-limits?  if so, can you
point me to them or repost them?

right now, i'm particularly interested in 7-limit 41-ET.
i've tried putting various unison-vectors into my
software, but while i always get 41-ET for the temperament, 
i keep getting 82-tone periodicity-blocks for the JI.
i don't know if these are cases of torsion (which is
what i suspect), or if there's a bug somewhere.


but aside from that specific example, i'd like to
have a nice list of TM-reduced bases for, say,
12, 13, 15, 16, 17, 19, 22, 24, 31, 34, 36, 41, 43, 46,
48, 50, 53, and 72-ETs, in the 5-, 7-, and 11-prime-limits.

There isn't a problem with the ones I did in that posting--namely, 
7-limit 9, 10, 12, 15, 19, 22, 27, 31, 41, 68, 72, 99, 130, 140. Monz 
wants 13, 16, 17, 24, 34, 36, 43, 46, 48, 50, 53 as well, and also 
the 5- and 11-limits. Some of these *will* lead to problems, so a val 
is going to be required in some cases.

the first one assumes the standard val (or something) for

The 5-limit needs to be what it is in order to include 81/80, and for
some of these, the 7-limit needs to be what it is to avoid torsion.

yes, that process should be made explicit though -- i'd rather 
explain that 24-equal sometimes doesn't have a reasonable basis due 
to torsion, and in those cases is best understood as an equal halving 
of each 12-equal step, instead of using hidden rules to provide a 
nice-looking answer.
