Mclaren, you are right to say that 3-D objects, when struck, invariably
produce a mix of inharmonic pitches. It is, of course, possible to
guide the pitch set by manipulating the shape of the object being
struck, as is done with cast bells, but the mix will still contain a
large set of inharmonic tones.

It is also true, from what I've read, that real musicians don't tend to
adjust their pitches toward JI any more often than they do away from JI.
The biggest consistent adjustment I'm aware of is to sharpen leading
tones relative to 12-tET, which of course is opposite from the
flattening that would be necessary to become closer to JI against the
fifth degree.

And it is also true that the ear doesn't have an "integer detector" as
such. Still, the ear can and does distinguish between the smoother
sound of an interval that is close to a low-integer ratio and the more
"energetic" sound that is farther from a low-integer ratio (when the
timbres are harmonic). Whether or not this distinction has direct
implications for how the best music might be produced is of course a
separate question.

When you list the objects in nature which produce inharmonic sounds vs.
the few that produce harmonic sounds, unless I missed it, you left out
the human voice, which is highly harmonic (plus a little white noise).
It seems to me a logical conjecture that the earliest music was a
combination of inharmonic struck objects and the harmonic sound of the
human voice.

When the largely-harmonic instruments produced in the last few centuries
(string, reed, wind, brass, ...) are added to the percussive and voice
mix, harmonicity becomes more represented than inharmonicity, and the
option of exploiting the special characteristics of near-harmonic
intervals becomes very feasible, though certainly not the only choice.

Why. he said all this before and we are going in circles at this point,
he believes what he believes i what i believe and we both have science
behind us. i just don't have time to answer all same material over and
over again.

OK a little music history first the west did music in unison and
octaves, then fifths and then something called thirds, and guess what
after that they added sevenths. Sounds like the harmonic series to me.
and the ear did it first

what would a kindergardener say

OK i am going to push the "Devils Advocate" on this one. Much of what i
take issue with is "not" necessarily my own stance but feel is still a
part of the equation. My basic point being is that one cannot disect
even one aspect of a work of art. Its findings are not only inconclusive
are more often than not unappropiate to the situation at hand. How you

As i stated before the question far exceeds what can be tested in a
labratory. If in our musical language we have certain intonation
tendency depending on where you are in a phrase than unlesds you kjnow
exactly what these are any test is meaningless. What we want from
Dominants is entirely different than what ewe want from a tonic chord.
we raise the third. why? because we are creating something that need to
be resolved.

yes when people sing the aimlessly wander within a pitch band, In fact

Boomliter and Creel asked singer to find the pitch they were attempting
to sing which is a far more acturate way in that it is influenced by

If you put different pitches in different ears the ear will hear

since according to all this scintific data on the perception of pitch ,
I see none wheree listeners attempt to produce an ET like 17 or 22. The
result would be far greater discrpancies than you will get from JI
If the tolerance is so great it seems to me that any mood does in an ET
could be done with a Cosntant structure of a JI in close approximity.

These scales only exist because of the computer and they are the
easieest things to do on them. They are not something that can be tuned
by ear and exstemely difficult with even a monchord.

listen to tuvan sing.
the fact is that then we can tune it by ear and if it doesn't exist in

In Ethnomusicaology thety have a system of measurement equivalent to
cents for rhythmn. All the test finds the same thing it does with pitch.
the beats are not equal nor are the subdivions of even the simpliest of
rhythm patterns. So you should encourge everyone to dispell of the even
beat because it doen't exist.

yes, a kindergartener would say "the overtone series". Then you pick up
a guitar and play a C13 chord, and compare it to 4-5-6-7-9-11-13 and
say, "well geee, thats not really it at all". I was dissappointed to
see the book 'Lies my music teacher taught me' making these sorts of
claims.

I started my quest with exactly this belief, and my first experiments
got me off of that track. I'm not exactly sure WHAT Western 'rich'
chordal practices are based on, but I THINK it has a lot more with
triad stacks (based originally on a JI trad) which are then warped till
they settle to some minimum energy level (which still can have a nice
buzz to it). (I guess I'm a kook that think that whatever JdLs program
does, te basic intent is correct, IN THE CONTEXT OF WHAT HAPPENS WITH
SUSTAINED CHORDS. Melodic cinsiderations and what happens when you mix
them are another thing).

I'm not saying that overtones aren't where all this stuff starts out,
and in McLarens post (where he was needlessly rude to you for three
paragraphs, but I skipped that part) after making the great claims
about inharmonic timbres being the majority of natural sounds he
points out that harmonic timbres seem to be the majority of musical
sounds. Works for me, I think.

Yes, that was interesting, however, thats generally my definition
of "post-modernism". There are no more "ism"s (and this is true
of all the arts).

However, almost none of the "ism"s were fully explored in every way
they could be, because you only got credit in twentieth century art
industry for doing something "new".

Given that, many of us are picking up a few pieces of "stuff" from
the past and putting them together in a personal style, exploring
perhaps some overlooked gem in the rubble, and finding other people
with common interests and goals.

Gee, like forming internet microtonality communities.

Musicians in general, maybe. But professional a cappella groups
of free-pitched, timbre-alike instruments (choirs, brass choirs,
string choirs) overwhelmingly manage to produce a closer
approximation of vertical JI than 12-tET. In Barbershop, at
least, this has been repeatedly verified with spectrum analysis.
Your ears will have to tell the rest.

Brian's post contains more references than that, but you'll notice
he confuses vertical and horizontal JI in several places.

But have you heard, "sharpen the fifth, flatten the third"? An
old adage that is taught in conservatories the world over.

There is some evidence that such a detector exists in the periodicity
mechanism. The spectral mechanism doesn't care any more than the
timbre.

Brian left out all the major free-pitched instruments of western
classical music, instead discussing timbres which might be of
interest to composers seeking new resources, or timbres that are
used in cultures whose music is not tuned precisely. He also
selectively ignores the fact that while instruments such as the
piano are inharmonic, they are only slightly inharmonic. Finally,
he either ignores, or is unaware of the fact that the loudest
few partials in the attack of highly inharmonic percussion
instruments tend to dominate the pitch they are perceived to have,
and that such pitches can be combined in harmonic proportions to
generate an ersatz JI effect, as is clearly audible in the work
of Harry Partch.

Don't be spoofed by Brian's "factual", but highly manipulative
article.

Not to my satisfaction, unless you've got something I
haven't seen.

On the other hand, there are at least three phenomena that
would cause a reasonable person to suspect the ear/brain
may be equipped with (which is not to say it "boils down
to") a small-ratio detector...

[1] Folks more reliably agree on the pitch of a
complex timbre to the extent its partials are
harmonic, with the possible exception of a few
specially-designed auditory illusions that can be
created with a synthesizer but which do not occur
in acoustic musical instruments.

[2] Intervals expressed by small integer ratios are
easier to recognize (identify) than other intervals,
unless the other interval is near in size to a small
integer ratio, _in which case it takes on the quality
of the nearby small-integer-ratio interval_. This
was observed by Harry Partch ("field of attraction"),
explains why musicians tend to use temperaments whose
irrational intervals approximate JI, and has survived
peer review on the tuning list (in this case, at
least as good as a vanilla scientific paper).

Another possible explanation of this phenomenon is by
appeal to a cultural accident that occurred in Europe
and spread around the world with the rest of European
culture. If this cultural bias is truly universal,
it is impossible to test this hypothesis today.

[3] Virtual pitch - I hope I don't need to go into
detail here... although Kraig recently stated that
difference tones are created between binaurally-
presented pitches... I don't think that's right.
Kraig, did you mean "virtual" or "periodicity"
pitch?

...The only hypothesis I know of that can explain all three
without going to fantastic lengths is that of an "integer
detector", and it seems plausible the evolution of such a
skill could have increased the fitness of early man by
helping him distinguish a language cast in human voices
(with harmonic spectra).

I'll agree with that.

The product of the numbers in a frequency ratio, also
called Tenney dissonance (actually the log of the product
of the numbers in a frequency ratio), has been found to
agree fairly well with something people can hear (unlike
the metrics mentioned above), and might be called
psychoacoustic consonance (or maybe "concordance", after
Easley Blackwood). It isn't intended to justify any style
of music or tuning, and it has the following limitations:

() Tolerance - it only gives reliable results when
its value is less than 100, give or take. This is
because when the numbers in a ratio get big enough
that their product is near 100, the resulting
interval is likely to be close enough in size to a
ratio of smaller numbers that it assumes the sound
of that smaller-number-ratio interval, as described
above. This limitation may be avoided by using
harmonic entropy instead, which is entirely
consistent with Tenney dissonance, but also defined
over the irrational numbers. Tenney dissonance may
therefore be considered a quick and dirty
approximation of harmonic entropy for ratios
involving whole numbers.

() Span - consonance and dissonance both seem to get
weaker as interval size increases past three octaves
or so. Also, all intervals are somewhat dissonant
when they are small enough to be in the critical
band, due to roughness.

() Timbre - harmonic, or nearly. It'll still work on
inharmonic timbres to the extent that beating doesn't
obscure the effect.

Too many exceptions? Maybe, but Denny Genovese, Graham
Breed, Paul Erlich, and Tenney himself all independently
concluded that this measure was useful.

True, to some extent. I'll claim that what the human mind
actually craves is information. That would mean random
noise is best, right? No- our sensory organs are better at
extracting information from some types of stimuli than
others...

All true, but the brain also has some surprisingly feeble
limitations on things like short-term memory, which may be
a reason that meter exists... why melodic scales larger
than 10 or 12 tones start to sound like smaller scales with
altered tones, etc.

Wouldn't it be better to say "harmonic series extractor" rather
than "integer detector"? The mechanism itself may or may not have
anything to do with the "integer" aspect of the harmonic series. What
you appear to me saying here is no different than what you were
saying in [1] above. One should hasten to add that there is more than
likely some relevance to _harmony_ in this observation -- see, for
example, Parncutt's book _Harmony: A Psychoacoustical Approach_.

True, but it's not a feature of our sensory organs that makes random
noise uninteresting, despite its apparently large information
content. Patterns are what give meaning to a string of data . . .
read up on Kolmogorov complexity and the like.

Try telling fans of meditational minimalist music that our brains
crave irregularity and complexity . . . it's completely a personal
preference.

Maybe. I was using "integer detector" because it was the
language used in the thread of which my message was a part.

I wrote a paragraph on that, but took it out for length concerns.
Also, I don't seem to place as much importance on it as you and
Keenan.

I'll have to disagree. I believe my original statement is
accurate. If you could tell me more, I could reply more
precisely.

Actually, I have read a bit of Kolmogorov and Chaitin.
I'm not aware of either having a formal way of dealing
with this... AIC is higher for random noise than most
music, etc. Can you give a reference?

In the context of the thread, my statement holds (I was merely
trying to correct what Brian's "people" crave). And to continue
in this context, minimal music has less information content per
minute, but is meant to be listened to in a state of mind when
minutes are faster. In general, it is the pleasant effect of
this state of mind that makes such music great (I like it too!),
but it isn't hard to fire such music out... all the stuff about
special intervals is hocus pocus, IMO.

So yes, I mean to say that it is a personal preference. I'm a
person who likes both very much. In both cases, I'd say music
is about artificially re-creating mental states -- learning in
the case of complex music, and relaxing in the case of minimal
music.

Ah- I think I see what you mean... Above all the perception
stuff, in the end, the mind is concerned with patterns, not
randomness. Yes, I agree. Gell-Mann agrees too. I'm not
aware of any Kolmogorov on this, so a ref. would still be
great.

So I do think that our brains are better at extracting info
from certain kinds of stimuli, but if they still get
randomness, they still aren't happy. They need some amount
of regularity -- not just because of memory limitations, but
also because music hopes to get the same emotional response
as real learning, which involves detecting patterns, etc.

I'll have to dig up my Information Theory textbook.

All what stuff about special intervals?
