Request for Assistance on a Scale

I am working on a project that requires prehistoric music.

I found this article in wikipedia
http://en.wikipedia.org/wiki/Prehistoric_music

and was wondering if anyone knew the correct scale interpretation of
this sentence:

The bone flute plays both the five- or seven-note scale of Xia Zhi and
six-note scale of Qing Shang of the ancient Chinese musical system.

Neither of the scales are listed in this reference on Chinese music:

If you have another suggestion that is non-Chinese it would be welcome
also.

Thanks!

i can't imagine that ethnomusicologist would not rip this page to threads. I think i will send it to their list! the idea that music relate to literacy is absurd. India is much more classical music and much older than the puny few hundred years Europe has climbed out of its beastly existence ( of human sacrifice BTW which we can debate has ended there [ Srebrenica <http://english.aljazeera.net/news/europe/2008/06/2008619125525418575.html>] <http://english.aljazeera.net/news/europe/2008/06/2008619125525418575.html> or by its colonies elsewhere [Iraq])

Jim French convinced me that the bones were used for reed instruments not flutes. try and make a bone flute. The spacing of equally placed holes leads to the subharmonic series of which Kathleen Schlesinger knew the most. Her book- The Greek Aulos- should be in every microtonal library IMHO :).
since it is hard to get i will mention that she site examples of where the exit hole is tuned to a perfect fifth below various notes in the subharmonic series. you can play as you which keeping in mind sub 7, 9,10 or 11.
Because of the times and her sexual persuasion, her book and work where attacked on the most trivial of grounds, yet appeared to be successful . Within the first few pages she shows the common tone modulations of the subharmonic series which gives you- the diamond! Which she argues was the basis of the Greek system. Her references to other indigenous music. the relation to Patch is uncanny in this regard and maybe his meeting with her made Mayer's work even more clear, or not.

It is the same intervals as the harmonic series except going down instead of up. if you divide a string into equal parts, usually done at the midpoint of the string or equally spaced wholes you will end up with this series.
A practical application would be in having a high drone and you sounded just intervals below.

It is much less explored than the harmonic series these days, but is just as musically viable. there is a certain depth it has that the harmonic series can lack.

on page 3 of
http://anaphoria.com/tres.PDF
there are some interesting subharmonic based scales using two different series instead of one.
But this is a little developed over the prehistoric idea. yet people where little different than us biologically so they might have taken to music way more than we give them credit for. I mean did birds have to learn monosyllable songs first? i doubt it!
i have notes on other scales that i will have to put up at some point. twist my arm if really urgent.
but i go to Japan on Friday

I would vote for the sort of pentatonic used by the Tuvans, which is
straight out of the overtone series. Not only do they use these scales
for singing (where they essentially have no choice unless they alter
the base note, which they sometimes do), but they also use them when
playing their bowed string instrument. Thus you've got tonic, pure
major second, pure major third, the jump to the pure fifth (funny how
they mostly avoid the sharp fourth), and the last note can have a dual
identity, either be the natural sixth when it occurs above the fifth
or the natural 7th when it occurs below the tonic. I have some
recordings of aboriginal music using similar scales. Can't get a whole
lot more "natural" than that.

But then, maybe it doesn't sound "primitive" enough for your purposes.

Say what?! If you divide a string into equal parts, you get the normal
harmonic series. Shorter length = higher pitch. Or does Anaphoria
represent a "Mystery Spot" outside the normal laws of physics?

In order to reproduce a subharmonic series acoustically, you will need
to multiply the lengths of a string or tube by whole numbers, not divide.

He said divide into equal parts, not divide by whole numbers. What happens if you multiply the smallest of the equal parts by whole numbers?

no i am afraid not. take a guitar and place the frets equally spaced apart and you will have the subharmonic series ( mixed with the distortion of string bending.)
there has been a few subharmonic guitars made and this is what you have

Another miracle! No matter how you slice it, frequency is inversely
proportional to length. ANY series of equally spaced holes will
produce a linear progression of length, thus a linear progression of
pitch. Both harmonic and subharmonic series are log progressions...
and last time I checked, linear and log were like night and day, cat
and dog, hot and cold, etc etc etc. in other words, never the two

I would also be very interested in the evidence which supports the
conclusion that bone instruments were always excited by a reed. A tube
is a tube, and I'm sure an experience kuval player (especially an
Iranian) cold pick up a clarinet without the mouthpiece and play it no
prob. No how is someone in 10,000 year who finds one of the joints of
a clarinet going to divine how the instruent was excited? Do tell!

all i know as that i have played many flutes with equally spaced holes and they gave me the subharmonic series except for the exit hole which, more often than not a fifth or fourth against one of the other notes. Schlesinger's critic by the way did not disagree with her math or measurements, just her history. French actually duplicated many of these by pulling them right out of the book.
i will leave it to Graham or the more mathematically inclined to explain the subharmonic series in terms you have a problem with. perhaps if you have a monochord you can plot out where the subharmonic series 8-16 is and observe the distance

Well, you have the write idea, but you're misinterpreting Kraig's
statements. Think of it this way:

If I take a guitar string, and I put 7 evenly spaced frets in it: one
halfway through the length of the string, one halfway between each of
those segments, and one halfway between each of THOSE segments, I will
have eight evenly spaced "positions" on the string. Not
logarithmically placed, but linearly placed.

I'll have the open string,

I'll have a string length which is 7/8 of that, so the frequency will
be 8/7 times that of the open string,

I'll have a string length which is 3/4 of that, so the frequency will
be 4/3 times that of the open string,

and so on. The full pattern is that the frequencies will be in this
ratio, where s represents the frequency of the open string:

s, (8/7)s, (4/3)s, (8/5)s, (2/1)s, (8/3)s, (4/1)s, (8/1)s

Now, if we recenter our perspective on this series, so that we call
the TOP frequency the fundamental frequency -- let's call it "f" --
we'll get this perspective:

(1/8)f, (1/7)f, (1/6)f, (1/5)f, (1/4)f, (1/3)f, (1/2)f, f

Which is a subharmonic series. Neat, eh?

Of course, what I meant to say was that you have the ryte idea.

Just out of curiosity, what does the fretting pattern look like for a
guitar that has frets placed at each harmonic from 8 to 32 or
something? How would that diverge from a 12-equal logarithmic looking
fretting pattern? Would the pattern still look logarithmic in nature,
but have even more of a "curve" to it or something? Maybe an
exponential looking curve rather than a logarithmic one?

If you say this then each of us probably uses different terminology for different things. For one thing, I find harmonic series to be "linear" because one of the most important properties of a period is its frequency -- i.e. either relative (in form of a ratio) or absolute (in Hz). As the tones in the harmonic series are equally spaced in terms of frequency (i.e. the differences between consecutive frequencies are the same), then I would call the harmonic series "linear" and the subharmonic series "inversely linear". A series of intervals of equal sizes (like a chromatic scale in 12-EDO, for example) is exponential because instead of keeping the differences the same, here the factors are the same (i.e. ~1.05946 for 12-EDO).

For another thing, how could equally spaced holes produce the steps you call "linear" if you mean equally sized intervals by that? You yourself said that length is inversely proportional to frequency, which, however, contradicts your second statement that a linear progression of length is a linear progression of pitch. Equally spaced holes would result in frequencies of 1/f, 2/f, 3/f and so on -- approximately, of course, because of the end effect.

Now, THAT'S a difference without a distinction. I defy you divide a
string into equal parts without using whole numbers. If you have a
string divide into 10 segments of equal length, then I'm pretty sure
that each segment will be equal to the total length divide by uh, um,
er, well...10, for example. Now, last time I checked, 10 was indeed a
whole number.

Then it is no longer "division", is it. By your own words...

from the top down rather than the bottom up. Still the same old mountain.

This is not just a shift of emphasis, this is a fundamental reversal
of the process; you are no longer "dividing" a *long* string length,
you are multiplying a *short* string length. The simple fact that you
started with a longer string in order to arrive at the generating
string length is of no consequence.

As I said, you must "multiply". A subharmonic series is, by
definition, "sub", below. You cannot descend in pitch by division of
dimensions of the string or tube. I'm not misinterpreting Kraig's
description, he is simply using the wrong words. If he had used the
right terms, I would have had no trouble.

I see my mistake in thinking, now. I was thinking a linear division of
the *octave*, since all modern wind instruments work on that
principle, as do all descriptions of the construction of sclaes using
string lengths. It is the space between the full tube length and the
half tube length which is divided into x parts by whatever scheme. It
didn't occur to me to think of dividing the *entire* tube length into
equal bits. Ditto with strings.

But my basic objection to the descriptions so far remains. The term
"subharmonic" means going down in frequency. Acoustically, you are
multiplying lengths, not dividing. The critical difference is which
length do you consider to be the generating length: the full length,
of the smallest segment. If it is the full length and you are
dividing, then it cannot be the subharmonic series. If it IS the
smallest length, and you are multiplying, then it IS the subharmonic
series.

The critical difference of course is that the one way allows infinite
progression through the appropriate series while the other is a
limited series. You can *divide* a length into however many equal
parts you want, and rise as far as you want through the harmonic
series. However, if you play the slight of hand you guys are playing
and take a short segment of a longer object as the generating length,
you can only descend through the subharmonic series to the longest
multiple of the generating length allowed for by the maximum length of
the object.

Anyway, in a much broader sense, and much more interesting, the whole
crux of the issue revolves around how primitive man approached the
issue. Did he first listen and then construct instruments in such a
way that the imitated what he heard, or did he just make things and
accept the sounds as they came? I suspect a some of both, but they
represent a fundamental difference in approach. Do we control the
sound we make, or do we simply make sounds? Does the ape simply pick
up any old stick to bash in the head of the ape from the other tribe,
or does he, after a spell, start seeking sticks which are heavier at
one end, or perhaps with pointy protrusions, or does he figure out a
way to wedge a stone into the split stick, or ...

Getting back to music, it is impossible to argue which approach is
more "natural", for the moment you CONSTRUCT something, you have
already made a quantum leap. In this sense, even something which seems
as simple as "equal division" is already an intellectual construct of
fairly advanced proportions. Thus any argument that the one or the
other solution is more "primitive", i.e. "less advanced", "less
developed", whatever terminology you want to pin on it, this argument
is bogus. As soon as we start to MAKE things, the genie is out of the
bottle, and we are free to design the object according to our
expectations. And one thing I am sure of, prehistoric man did a good
bit o' singin' long before he started to make melody producing objects.

Granted, the foreign sound of a scale using a subharmonic series would
perhaps present the dramatic effect of being "something different"
which may be advantageous to the ultimate goals of the "project" at
hand, whatever it may be (documentary film? theatre play? Hollywood
pseudo-historical narrative?). In that case, the possible veracity
(which cannot but be suspect in all cases) of the approach is of no
consequence, so one may as well grab whatever scale one wants.

Maybe we have a bone flute (or was it a reed? still waiting for that
explanation) with equally spaced holes precisely because the guy who
made it played it and thought, "Yuk! This thing doesn't sound good at
all!" and threw it promptly into the beat bog.

Who knows?

Now, "dividing a string into equal parts" (which is what he said, need
i stress again) is EXACTLY what I and the other 2 professors teach the
students of acoustics at ESMUC in order to produce the HARMONIC (not
the lack of the prefix "sub") series. It might appear that we are in
good company in this practice:

http://www.music.sc.edu/fs/bain/atmi02/hs/index-audio.html

http://www.cartage.org.lb/en/themes/arts/music/elements/generalities/harmonic/harmonic.htm

http://graham.main.nc.us/~bhammel/MUSIC/ovrtns.html

http://www.answers.com/topic/harmonic-series?cat=technology

http://www.guitar-vacation-retreats.com/resources/overtone_series.html

(I could go on and on listing literally hundreds, but I hope you get
the point)

ALL of which talk about DIVIDING the string up into equal parts to
produce the HARMONIC series.

Now, practically speaking, you CAN arrive at a limited subharmonic
series by FRETTING a string using any ONE set of equal division points
and then considering the SHORTEST FRET to be the fundamental position,
, but this represents a significant divergence from the normal state
of affairs and the normal approach when designing or talking about
string instrument construction. Somebody who doesn't know what you are
on about can't get it, precisely because you have properly described
neither the theory (i.e. multiplication of the generating length) nor
exactly what you are doing (fretting)... especially if the are used to
the normal description of how to produce the harmonic series.

It's not weaseling, it's just trying to keep the terminology straight.
If I were to teach my students exactly what a "subharmonic series" is
(and I think I will next year, it's an interesting idea!) I would
start by STRESSING that it is the reverse of the harmonic series in
EVERY aspect, involving multiplication instead of division,
frequencies going DOWN instead of up from the generating tone, and a
real world a short tube or string made progressively longer.

BTW, I DID get the whole business about linear and log totally messed
up, thanks to trying to recover from a "contact" hangover and almost
no sleep when I wrote the message, due to the biggest party night of
the year in Catalunya, said partying of which I did not partake but
the constant din of thousands upon thousands of exploding firecrackers
and rockets until almost daybreak DID deprive me of a normal night's
sleep. The harmonic series IS a linear progression of frequency, no
matter which direction you move through it, up or down, but the
subharmonic series is NOT a linear progression of frequencies, not in
any normal sense of the word. Perhaps it is derived by a "reverse
linear" process (though the only references to "reverse linear" I
could find was complex stuff about data analysis), the series of
descending frequencies which a subharmonic series describes is NOT linear.

Glad you liked the other posts, anyway.

Dividing a string into equal parts won't produce a harmonic series.
How could it? The distance along the string from the 2nd harmonic to
the third harmonic is obviously not equal to the length from the 1st
harmonic to the second, if we're counting the first harmonic as the
open string. Dividing a string into equal parts will produce a
subharmonic series from the perspective of the shortest length used in
the string.

The crux of the matter, and the original source of confusion in
Kraig's post, is what you mean by "dividing". In acoustics, when
talking about the harmonic series in regards to tubes or strings, it
means that the string vibrates in segments which divide its length
into equal parts; 2 equal parts for the second harmonic, 3 equal parts
for the third harmonic, 4 equal parts for the fourth harmonic, etc,
the rule being that in order to produce harmonic X, the tube or string
must be divided into X equal parts, ALL of which are simultaneously
vibrating. You can, of course, physically produce these frequencies by
touching your finger lightly against the string at any one of the
division points for the mode in particular, or in the case of wind
instruments, opening a very small vent hole at any one of these
division points, though in the case with even-numbered modes, some
points may produce more than one harmonic mode of vibration.

Now, if for you "dividing" means placing frets at points which
represent a series of equal divisions of the total string length, or
in the case of a tube, boring holes at these points, then the series
of notes produced when the tube or string is redimensioned by the act
of placing a finger on the fret or opening a large tone hole
(essentially changing the length of the tube), it cam be considered as
a means to produce a subharmonic series IF and ONLY if you consider
the shortest segment thereby produced to be the fundamental length,
i.e. the length which generates the whole series. Note also that you
are not "dividing" the vibrating object in any acoustical sense, but
rather what you are "dividing" equally is only the measurement of the
object's initial length in order to define a series of different
sublengths.

So the former is an acoustic interpretation of the word "divide", i.e.
literally dividing the vibrating object into smaller units, all of
which are vibrating, and the latter is a completely practical "get out
the ruler" and figure out where to put the elements that will alter
the functional acoustical length of the object. The former literally
produces the harmonic series, the later produces a SCALE which, when
played in a descending direction, follows a limited subharmonic
progression. While the latter may suffice in the instrument workshop,
it won't garner you a passing mark in any acoustics or physics class.

Ah, I see what you're saying now. Kraig was referring to putting
evenly-spaced frets down, you're referring to putting unevenly-spaced
frets down at places where the string would be divided into 2 equal
parts, 3 equal, 4 equal, etc.

i was talking about a string, a physical object.
there is nothing in your original description that says you have to do the process for each harmonic so i am afraid your own definition lacks clarity being incomplete. fail.

why anyone would assume that if i said divide in equal parts, that this would be a process you would repeat over and over again for each harmonic. only if you already knew this. So the confusion is in just how you are used to thinking of harmonics on a string.

if i said divide this paper in equal parts starting at the halfway point. what would most people do.

This is another use of the term used by improv and other instrumentalist. pulling extreme pressure on the string producing lower tones than the fundamental. it is a may or may not be a different thing all together. i don't know enough about what is actually going on.

There may be an easier way to think about and conceptualise the frequency and ratios of the sub/harmonics..

Sub harmonics ratios may be considered as the reciprocals of the harmonics ratios.

e.g. harmonics 3/2, 4/3, 5/3 ..... etc.
sub harmonics 2/3, 3/4, 3/5 ..... etc.

The what, which, why, where, when and how exactly of the sub/harmonics are other questions.

I shall resist the temptation to comment further;-)

musically it is found most often when the drone is higher and the melodic lines are below.
but it should be understood that if you have a subharmonic scale, you could use any tone as the tonic; any of it modes.

I imagine someone on this list knows more about this particular bowing technique.
i can say little here without someone finding issue with it.
it does not occur in nature acoustically ( or possibly rarely depending on the above)

think of a string half the length
as done with a fret, you will have the octave. let say this distance is 16 inches,
if you put a fret every inch between this octave point and the nut and play this series
you will have the subharmonic series 16 through 32.

well then let me say you can use the relationships found in the harmonic series to make a scale. and likewise the inversion.
The music of Ben Johnston commonly does just this.

Since the subharmonic series is not found in nature (for the most part) i felt no reason to qualify.

8-10-11-12-14-16 in terms of harmonic or subharmonic relations is just one of many examples. personally i prefer examples.

No, you are talking about the measurement of the space on the neck of
the instrument underneath the string. You do not divide the string
itself, you simply stop it at different lengths which represents
division of its MEASUREMENT. NOT the same thing.

Hmmm. I'll try to communicate this to the entire acoustics community
world wide, that our standard definition lacks clarity. It's a huge
task, maybe you can help? You take all the physics/acoustics teachers,
writers, theorists on your side of the world, I'll take all those on
mine. Ready? Go!

That's precisely the point. Saying "divide the string into equal
parts" already IS something thousands of people say in a certain
context, so it is YOU who is pissing against the wind here.

So many of us used to thinking in this confused way!

Which paper would that be? The imaginary one that a computer screen
represents in the minds of some people? Sort of like the imaginary
length of the string (not the string itself) that you are dividing?

And besides, what you actually said was:

Now the "or" in this sentence implies multiple solutions to the
problem. Obviously the option of starting at the center implies
progressive halving, but the "equally spaced wholes" option would seem
to imply the other possibility, which is of course dividing the length
of the string (again, not the string itself) into any odd number of
equally spaced wholes, i.e. divided by whole numbers, or dividing the
length by multiples of 6, which have a division point at the center
but are not derivable by further progressive halving. So yeah, your
sentence implies multiple solutions, not just the one of progressive
halving you now seem to wish to have said in hindsight.

fine thanks for clearing that up, although we don't know if it is being over driven or not.
It does not appear to be so.

Well, if you're looking at a subharmonic series, the fundamental is
usually considered to be the highest tone.

The word "harmonic" simply means that the elements of the set are all
multiples of the generating element. So if all of the frequencies of a
scale are multiples of the lowest tone, then the scale is a harmonic
series. That said, generally speaking a scale is usually imagined as
existing within the confines of an octave, so by definition a harmonic
series cannot be a scale and vice versa.

However, it IS possible and quite common that real harmonics of a
fundamental frequency are used as a musical scale. Examples abound,
from natural horns and trumpets to tromba marina to Tuvan singing:

I generally agree completely with that approach. That's exactly why I
choke on the idea of a subharmonic series being created by reducing
the length of a long string. It's putting the cart before the horse.

Ah. That's an interesting question. You're referring to string
"crunching", as it were.

I'm not sure how that works any more than I'm sure how a speaker can

It would seem that what would be important is whether it is musically viable or not.
In regard to prehistoric music, i do not envisions strings being the first instruments.
Tuvan music is very beautiful, yet harmonic singing appears to limited around the world to a few places . (Angola is another locale although difficult to find recordings)
Still it could be quite old or not. We have no reason to assume that prehistoric music was the same the world over.

A subharmonic series WILL be created relative to the frequency
corresponding to the shortest division of the string. Why do you
insist that the center frequency of any series of harmonic
relationships has to be viewed as that corresponding to the open
string?

Pipes vibrate at either 1/2 (open at both ends) or 1/4 (closed at one
end) of the wavelength in the open air. I think what you mean is that
waves can form internally which have half lengths which are equal to
divisions of the total length.

That's a different thing altogether, the mind filling in the missing
fundamental. And then there are Tartinni tones, which is another thing
yet.

It can't, not under normal conditions. The description of increase
pressure with slower bow speed makes me suspect she is mucking with
the Helmholtz motion, maybe causing the normal wave to be rereflected
once sending it back around the loop where it is again reflected from
the bow and then when it finally comes around again it creates enough
displacement to overcome the increase friction caused by the extra
pressure? Don't know, just an idea. But this has nothing to do with a
subharmonic series per se, since her audio samples make it obvious
that the first subtone produced is NOT the octave, followed by a fifth
down followed by a fourth down, which would be the case in a real
subharmonic series.

these are harmonics of the tube. not subharmonics.
and this series will produce what Paul had pointed out.
We cannot find the subharmonic series in nature or in a tube. you have to drill equidistant holes in it to force it to sound this series.

One can base a scale on anything and people do.
The point is that it appeared people used these subharmonic scales quite far back, and they stuck with them. We still find flutes/winds of this construction the world over.

Then the question is, how does the speaker produce (3/2)f, 2f, (5/2)f,
3f, (7/2)f, and so on, so that we perceive (1/2)f as the fundamental?

Wait, I'm confused... Are you talking about the equally spaced frets
or the subtone crunching of a violin?

I missed the link to the sample, but thanks for clearing up that these subharmonics are different than the ones we are referring to.

this is a good perception question.
i imagine with a gong or more with a tam tam the brain might fill in a bass based on the cues it is presented which might not coincide with the actual source. i don't know

Kraig & Paul --

you are writing past one another by confusing two ways of producing subharmonic relationships: the first is a division of a string into equal parts, which are then related subharmonically with the shortest part the "fundamental" (/1 or, better, perhaps, Wilson's term "guiding tone") or tones which are related as subharmonically to the whole length of a given string (each successive string then 2x, 3x, 4x... the length of the first, sounding, respectively, at 1/2, 1/3, 1/4 etc. the frequency of the first).

One can, in fact, drive a bowed string into oscillation at the first one or two subharmonic modes by bowing with increased pressure, a technique I use in my 2nd Quartet. I heard this first in Crumb's quartet _Black Angels_. The violinist/composer Mari Kimura has become rather proficient at this technque, and samples of her playing and research can be found online.

a flute without holes will produce a harmonic series.
but if you drill holes randomly and play this it will not be harmonics of this tube.

i am not sure what you are asking a reference to.

I'm not really a string player, but this is one of the tricks I can
do with a fiddle. The first mode of playing with increased pressure
is indeed an octave below the fundamental and, by further increasing
pressure, on a good day, you can get the twelfth below, thus the
subharmonic relationships. Kimura is now able, by varying pressure
very subtly to play pitches in-between these modes. I can't
duplicate that, but, as a trombonist, I believe that what she is
doing is exactly like brass players playing "falsett tones" between
the lowest ordinary pitch and the highest pedal tone, thus playing a
pitch continuum although theory says there should be an unplayable
tritone gap between the two. Falsett tones are produced by the lips
vibrating at an intermediate mode (i.e. 1.5 x the pedal tone
frequency) with, of course, considerable adjustment by slide and
lipping up or downward.

That's right, except 12-equal string lengths (and hence fret positions
as measured from the nominal bridge position) aren't proportional to
the logarithm but inversely proportional to the exponential.
Subharmonic is proportional (linear). Harmonic is inversely
proportional which is also called hyperbolic (with an offset in this
case).

For fret number n, the relative string lengths (full string = 1) are:
12-EDO: 1/(2^(n/12))
Subharmonic: (32-n)/32
Harmonic: 8/(n+8)

If measuring from the nominal nut position the relative distances become.
12-EDO: 1 - 1/(2^(n/12))
Subharmonic: n/32
Harmonic: n/(n+8)

But you either already knew that, or didn't really want to know
because this isn't tuning-math. Sorry.

And I say "nominal" because the real nut position is set forward from
its theoretical position by about 0.5 mm (shortening the strings) to
compensate for the increase in tension when strings are fretted as
opposed to open, and the bridge or saddle-pieces are set back between
about 1 mm for treble string and 5 mm for bass string (lengthening the
strings) to compensate for end-effects due to string stiffness.

the subharmonic is the inverse, the mirror, the reciprocal, of the harmonic series. Like how the minor is to the major. or the major scale to the Phrygian.

yes. it is more involved as to the size of the hole and where you start your series of holes. i can't help you with that i am afraid.

This is in fact desirable, since when the wavelength is shorter
than the diameter of the driver, the sound becomes highly
directional, which means you need to stand directly in front of
the speakers to hear it. This is a principle reason for tweeters
being small, and, existing at all.

It was explained wrongly then. Since sound is a longitudinal
wave, it is the *throw* of the driver, not its diameter, that
is important to low frequency reproduction.

This does happen to some extent, and in fact there's a
company that sells a DSP to add in harmonics to boost the
perceived bass (often used with NXT-type speakers, which
lack real bass). It was also important in the phone
system, where for decades (still?) the system couldn't
carry frequencies as low as the fundamentals of typical
male speaking voices.

If one partial is louder than the others, especially in
the all-important 100-800 Hz. range, you may hear that
out and not notice the other partials as much. The brain
is very aggressive with pitch extraction. Not until we
get to stuff like snare drums does the thing give up the
ghost. Sometimes they can be ranked higher or lower that
some pitch, but you'd be hard-pressed to say exactly what
the pitch is.

Uh, that looks like an RF calculator. Wavelength is
speed/frequency. Light travels through air significantly
more quickly than sound. :)

I didn't say the throw of the driver had to match the
wavelength. Rather, it has an impact on the efficiency
of the low-frequency sound that can be produced.

It makes a difference because if f is the actual frequency, and you're
saying that we want to get the harmonic series of f/2 so that the
brain can "hear" that phantom fundamental in there, we're going to
need the harmonic series of THAT frequency, not the harmonic series of
f Putting a harmonic series over f will cause the brain to hear f as
the phantom fundamental, and we want to hear f/2.

So the harmonic series we want is (2/2)f, (3/2)f, (4/2)f, (5/2)f,
(6/2)f, (7/2)f, etc. and then the brain will hear (1/2)f as the
phantom fundamental. How does the speaker generate (3/2)f and (5/2)f
and such?

So what is proportional to the logarithm? Nothing?

Interesting. So if I was actually refretting a guitar, would I measure
these lengths from the actual nut position, or from 0.5 mm down past
where the nut lies? I just defretted this guitar, and I was going to
make it fretless; but I might do 19-tet instead, or even 31-tet if
it's a viable option.

Mike;

Since you have defretted a guitar, before refretting it, may I make a suggestion.

Instead of cutting the new grooves for a permanent refret, fill the old grooves with plastic wood and sand the surface..
By tying nylon first or second strings around the neck at various positions you will be able to experiment before deciding which fretting system to go for.
It is easiest to tie the nylon frets below their eventual position and then push them up the fretboard, which will tighten the knots, into the desired location.
I suggest that you make the knots in the uppermost position around the fretboard, so that you minimise the restrictions to your hand movements, although you will feel the nylon strings at the back of the fretboard.

As you know there are thousands of possibilities for the fret positions for you try.

Here are the specs for a couple which work for me:

http://www.lucytune.com/guitars_and_frets/frets.html

Doing it this way gives you the opportunity to find what works best for you without the need to be "stuck" with any particular choice.

Have fun!

Alright, the the question I have is, in what sense does a speaker
generate the first subharmonic, and is it the subharmonic of the
frequencies being PLAYED, or the subharmonic corresponding to the
wavelength of the speaker?

Sounds to me as though it must be of the signal, as you can "hear" low frequencies even on tiny "ear buds".

How exactly is it that a speaker can do this, and can it generate a
whole subharmonic series, or just the first undertone?

Okay, let me rephrase: WHY does a speaker produce the first undertone
of a given signal, if that signal isn't there in the original
recording?

Man, we're going in circles! If it's a phantom tone, then the speaker
will need to produce the harmonic series of that tone. And if that
tone is f/2, then the speaker has to produce 2f/2, 3f/2, 4f/2, 5f/2,
so that the brain can fill in the f/2 phantom fundamental. And what
kind of nonlinear distortion produces 3f/2 and 5f/2 and 7f/2, for
example?

Do you mean whether or not subharmonics exist sounding simultaneously
in nature...? Or just the series sounding simultaneously?

Er, I mean the subharmonic series sounding simulateously, like the
harmonic series, or just the series being played out in some fashion?

I don't know of any useful meaning that could be attached to string
lengths which were proportional to the logarithm of the fret number.
But of course in the case of 12-equal the fret number is proportional
to the logarithm of the frequency.

It can also be confusing because the "inverse" in "inversely
proportional" is different from the "inverse" in "the logarithm is the
inverse of the exponential". Inversely proportional really means
_reciprocally_ proportional, i.e. proportional to 1/(whatever).

Some manufacturers don't bother with nut-setforth and they may use
different amounts so I can't say. I suggest you measure all the
existing fret positions (at least up to the 12th) to the nearest 0.25
mm and put them in a spreadsheet. Then take your scale length
initially to be double the distance from nut to 12th fret and try
adding various amounts to all the fret distances (and twice to the
scale length) until you get the best agreement with the theoretical
formula. (You could make a spreadsheet on Google documents and invite
me or others to help you get it right).

Here's a paper of mine you might enjoy.
http://dkeenan.com/Music/MicroGuitar.pdf
There's an untried Blackjack design at the end.

Another method for rapid prototyping of microtonal frettings is to use
1 mm diameter nylon monofilament fishing line (hard trace or leader)
and file notches in both edges of the fingerboard (or in something you
attach to both edges of the fingerboard, like some wood, plastic or
wire) where you want the frets, then tie the fishing line under the
top strap button and just wind it around and around the neck
spiralling up through all the notches and eventually tying it off to a
tuning machine. I learnt this trick from one Charles Neville. See
http:// www.cyberferal.com/UncleBob/gallery
Click on a photo to zoom it.

We independently came up with the same idea of using one continuous
piece of fishing line for all the frets. I laced them _through_ a
hollow tube neck with holes, he wrapped them _around_ a solid neck
with notches.

The speaker ideally is not a sounding membrane, but a piston that moves the air. It shouldn't, but nevertheless may contribute its own vibrations across its diameter, but the frequency is due to the magnet behind it and its possible acceleration. I think you mix this up with an old saw about the frequencies transmitted by telephone, where the lower ones are or were simply filtered away.

Wow, that's a great idea. I might actually do just that.

On a side note, my nephew was reading my posts on this forum, and he
read these ones out loud:

Do you realize that we're slowly losing all sense of how to
communicate with normal people? I don't know what to say.
