Firstly a question, do older Shakuhachi predominantly have an utaguchi insert or not ?
I make mi Jinashi without an insert and so the blow edge most often has a slight ceration due to the bamboo fibre. As much as i fine sand to get a smooth regular curve, there remains a ceration. An insert of bone or plastic is smooth, without ceration.
I don't know whether this influences timbre, it may.
Secodly, I have used at least four different species of bamboo, varying in wood density, which is probably due in part to the species but also to the age of the culm as I think it develops a higher percentage of silica as it ages. This would have some influence on how the material cures over time and how it 'petrifies', which as you know, is morphing towards stone.
I have not made a decisive opinion regarding different species as to timbre but a harder wood will allow a smoother bore surface, I am confident that at a micro-fine level, the surface texture has a big influence on timbre and the resonance of the harmonics.
For example, with the blow edge itself, as it is being formed, it starts out coarse and is refined to a smooth surface, and there is a very noticable change in sound as this change happens, from a [dirty[ sibilant sound to a cleaner, fuller sound with more defined character regarding harmonic presence.
Also, after drilling a hole, it is rough at the edges, and changes quite dramatically particularly as the inner edge is cleaned, smoothed and bevelled, if it is bevelled, this is not always necessary.
I don't have an oopinion on a flute improving the more it is played, other than, yes, I get intimately familar with the character of each hole and the way the flute responds, and the wood warms with handling and even the warmth and moisture of the breath. BBut I never play the same way twice, I am in continuous flux myself.
I suspect with playing, oils and such will coat the bore one way or another, as the outer surface takes on body oils, this could have an influence.
Finally, I like my Scotch aged and at room temperature, so feel this would also apply to my Shakuhachi.

This is a fun argument.
Mentioning the Selmer Alto.............Steve Lacy was an endorser of Selmer saxophones. I saw he had a new one and asked him how he liked it. He said the other one he used for decades died and he didn't like the new one as well. But then he said the best sounding saxes he had ever played were a set of the original Adolf Sax saxophones he played in a museum. I asked him what made them sound better. He said the metal vibrated more than on more modern horns.

Musicians are a funny breed. Coltman's experiment raised a firestorm of protest from players. Here is what he had to say about it:
"First, the player and experimenter rarely, if ever, have any way of knowing whether the instruments they are comparing have differences other than those of the material, in fact I know of no reports in which the claim for 'no other variation' is made. Second, the musician cannot, under normal playing circumstances, dissociate his personal preferences and prejudices from the question at hand. In the case of the three 'flutes' I constructed, nearly every player who picked them up and tried them had a preference for one or the other. Often he would describe his impressions - the wooden flute has a 'fuller' tone, the silver one 'projects' much better, etc. He was then usually baffled to find that he could not identify any of the instruments under the 'blindfold' conditions I described. The plain facts are that his judgment is influenced by preconceived notions and mental associations of tone quality with other properties of the material. This is a normal human reaction, intensified in the case of those trained to incorporate feeling into their art, and to whom the instrument becomes, in effect, an extension of their own body and personality. It is just not suited for answering narrow, objective questions like the one I posed - namely: can the material of which a flute is made directly influence the tone quality produced? "
Coltman himself is an excellent flutist, and completely redesigned the scale of the Boehm flute to make it much better in tune.
BTW, the Adolphe Sax saxes were not made of thinner or much different metal than modern ones, but Sax did produce what he called a "conic parabola" as a bore shape, in which he placed great credence, and which has since been abandoned due to manufacturing difficulties. His bore dimensions were quite different from those of modern saxes, which are designed for projection. I have an old Conn soprano sax from 1924, and the sound and response are worlds away from those of modern design. I and many others find the old horns have much nicer timbre, but the intonation is all over the place, especially in the top notes. Noewer horns include a different conic section near the neck area, which locks the intonation in much better, but at the expense of a certain kind of sweetness of tone and liveliness of response.

I have a 1928 Martin soprano which I bought after trying all the soprano saxes in NYC because the tone was superior. And since I always play sax out of tune that didn't matter!

The smoothness and edge of the utaguchi are critical to timbre. Smoothness of the bore has a large effect on losses at the boundary layer: basically, a rougher surface slows down air molecules close the the wall, converting their energy to heat. This also has large impacts on the resistance, response and timbre of the instrument.
An interesting an often overlooked point is the presence of any sharp edges in the bore. Any sharp edge increases turbulence, which in turn increases acoustic losses, which get greater as dynamic intensity increases. In fact sharp edges can create a limiting case as blowing pressure increases, which will then limit maximum achievable sound intensity. Benade cites a case where five minutes of playing caused enough wear on the sharp edge of a clarinet fingerhole to noticeably change the playing characteristics. This is a second-order function, though: you get the most change when the edge is sharpest, and less and less as it is more rounded. I have the mathematical formula for figuring the losses based on edge diameter and frequency, but suffice it to say that the normal wear on the outside of shakuhachi fingerholes over the years can have a significant impact on the playing characteristics, and by all means undercut the insides when you build the flute!
I like that very much: always being in flux with oneself. A very poetic and accurate description of subjectivity

I could see where a cracked and repaired flute could have the repair settle. I've been reading some of Toby's posts some more too. It seems he's saying that, acoustically, softer material should give the same results as harder material. That seems entirely counter-intuitive to me.

It's not at all counter-intuitive if one attends to what Toby is saying here:
1. The sound is produced by a vibrating column of AIR.
2. Hardness/softness is a relative thing, and air is VERY soft compared to anything you can make an operational flute out of.

Have you ever felt the air coming out of a compressor? It's a lot harder than you'd think it could be, to the point of hurting against flesh. I know that is less pressure than that coming from our embouchures, but I'm not all sure how soft those pressure nodes inside the flute really are. It is compressed air after all.

The air column in the shakuhachi cannot have more pressure that what is put into it by the air pressure coming from your lungs. It is also instructive to note that the radiated sound power of any woodwind instrument is less than 1% of the power put into it. More than 99% is lost to viscous and thermal losses, mostly at the walls. This means air being slowed by "friction" and transferring its energy to the walls as heat, not energy spent flexing the walls, although there is some of that kind of thing happening at your soft fingertips. This is the vibration that you feel.

Toby I didn't think you had the experience you have with shakuahchi or other instruments BECAUSE of your statements.
I still think you're missing something, and thereby denigrating the views of MANY other musicians, but IMO that's your problem not mine, and I mean that sincerely, not spitefully. You think musicians are a funny breed, I think shakuhachi scientists are a funny (actually funnier) breed. I can agree to disagree with you on that. I will add though that you're using loaded words "funny breed," which is a quick way to get me to exit a debate (perhaps your intent?), and that how long or how wide one's experience is is only a small part of the picture, and not the most important one by a long shot--what matters is what you can do with the flute/sax/piano/violin you're playing. Send me a link to your CDs or send me some sound files if you want to convince me of your expertise.

I'd like to hear some sound files too, but a Dai Shihan from Yokoyama is a pretty convincing credential.
This is exactly the reason why, despite Toby's seemingly bullet-proof argument, I think there is still some work to be done on the science side. No double-blind equals no conclusive scientific proof, particularly when the rationale behind the conflicting observations is chalked up to being that some very highly trained musicians must be hearing things that aren't there. I'll concede that they might be hearing things I can't hear, but then I very often hear new things in familiar recordings, so I know I may not be hearing everything that's there.
In the '70's when the famous "material doesn't matter" experiment was done, it was common for people be amused by how thier minds could be tricked to perceive things that aren't really there. It was pretty much common knowledge that psychosomatic illnesses existed due to a focus on the subject by popular TV shows. I'm not sure what the doctors thought back then, but these days I know for sure that doctors do not chalk up much as being psychological. If all the tests for conditions that would result in the symptoms turn out negative, they typically look for some other explanation, and wouldn't even think of suggesting it's all in the patients mind. So why, and in this day and age, would anybody doubt when almost every very highly trained musician says there's a difference in the sound when different materials are used.
When someone get's a double-blind set up using robotics or something and every highly trained musician tested can't tell the difference between music played on similar instruments with identical dimensions, that's when I'll start doubting the perceptions of the master players.
I find it hard to believe that anyone would dimiss the observations of so many credible and brilliant musicians based on old, obviously flawed (not double-blind) experiments where the experimenter explained away anyone saying that they can hear that his theory is wrong by saying they are being misled by pre-concieved notions and that they aren't in actuality hearing any difference.
It kind of sounds like my favorite definition of "scientific method": collect as many data points as you can, toss out the ones that do not fit your theory as "anomalous outliers" and forget about them.

Oh, I'm sure that Ko Ro Ro is well-pleased with his own competence, but, according to his lights, should I not also be able to
"experience" it in order to make my own judgement on the matter?

That sounds scientific to me. In fact, it is currently in practice by many in the "climate industry".

Ed, there's just so much love in everything you say I can tell you must be very enlightened. That scientific method definition is a paraphrase from a scene in Donald Duck in Mathmagic Land. Somewhere near the end I think, it should be in here somewhere: http://vidbunker.com/disney_59_donald_i … _land_3of3

Musicians are a funny breed. By the way I called Toby "Shakuhachi Scientist" similarly to how I called you "Über-Sensei".

Anybody who calls themselves things like "master" or "expert" should have some evidence to demonstrate this to the general public.

Alas, blathering notwithstanding, it's still the definition of an ignoramus.
Additionally, I've never noticed that seemingly enlightened beings were inclined to suffer foolishness gladly.
