There's pretty smart fellers (or fart smellers) out there in the world, much smarter than any of us that I'm certain can figure these things out. We have nanotechnology, Space X, Large Hedron Collider...maybe it's because "they" don't think tubas are important enough and see us as ants arguing over a piece of tree bark.

I'll quote my friend the now-retired college physics professor / horn player who said that a concrete flute with the exact same internal dimensions / smoothness / etc as a zillion dollar platinum custom handmade flute, would sound exactly the same because the sound has to do with the internal dimensions. I have no idea how that relates to tuba but it is fun to post it in this thread.

If this were true, then you'd see a whole lot more concrete flutes..maybe even fiberglass, titanium, etc. I think instruments and their makers' million dollar original ideas have worked so well for hundreds of years there's really nothing to debate. A concrete tuba would make a neat center piece for NAMM in 2022 though

I'd like to revisit that glass tuba!!

Maybe. This issue is more deeply felt by woodwind players, especially clarinet. Which may be of wood, plastic or metal, and many players are certain there's a significant enough difference that no self respecting player would play anything but wood, unless outdoors. Flutes can be made of wood, and the way I remember it, the conventional wisdom is that it gives them a more penetrating tone. Acoustically, wood is more dead, than metal, and might be soaking up some harmonics? At any rate, for me that's the function of any resonance in the body, to subtract rather than add. I found a terrible youtube recording or two of that glass bugle mentioned above, and to me the sound seems rather harsh. But poor fidelity recording, who knows.

Carbon Fiber?

I'd definitely be interested in trying a carbon fiber tuba. I've played a small bore cf trombone. It was fun and sounded fine. The group of musicians standing around all agreed that my old King 2B Silvertone sounded better. But I'm sure there was all kinds of bias at play. And whiskey.

My post was referring to brass. Just adding my $0.02 to the conversation. I'm not looking for a magic tonal quality as much as I'm looking for a durable horn that doesn't break the back. And by horn, I mean sousaphone (cuz thats what I do). So my preferences might be slightly out of line with the sitting down and counting rests set.

curious:
The King Silvertone trombones that I’ve seen feature solid silver bells and are actually smaller than size 2B King trombones. They are quite old and did not have a slide lock. Is that what yours is like?

No, it's almost identical to an HN White 2B Silversonic.
Similar size with a slide lock and sterling bell.
I believe it dates to '42 or '43.

We've made ships out of concrete, why not tubas?

I recall seeing the wreck as a little boy.....all the time before that, my father building up the excitement in my incredulous mind the concept of such a crazy thing.....

All the comments about what the player feels seems to indicate the player gets much (or at least part) of the perceived effect.

So.. Does thickness of the brass, hydro vs. hammered, etc/whatever have more effect (perceived or real) on the sound column or on response? Is it really about sound or ease of play? Or both? Neither? Or simply the player's perception?

We're neither percussionists nor stringed instrument players.
Rather, we are sympathetically-activated air-column vibrators...and it's not even about "moving air". Rather, (again) it is about vibration. Were it that (and it's not possible, obviously) we could vibrate our lips without moving air past them, the air column within the instrument would still (I believe) vibrate sympathetically with the lips.

Of course, thinner/lighter instruments are going to physically vibrate more in our hands/laps/against our chests (which will affect our own perceptions of what we're hearing being emitted from our instruments), but that physical vibration - by/of a wind instrument - has very little (imperceptibly little, I believe) to do with what is heard by others.

Maybe slightly unrelated to this, but in a survey conducted by real scientists, violinists could not tell the difference between century-old Garnieris/ Stradivaris and new violins, and in fact preferred spanking new off-the-shelf instruments.

Maybe a similar experiment involving thin/thick and light/heavy instruments would yield the same result?

Going from a very thin Cerveny to a tank-built JP, my experience is this: Thinner instruments DO dent more easily.

A trend - with all types of musical instruments, since the mid-1970s - has been to figure out ways to make them be able to be played louder…this: over all other characteristics.
Not only (with so many makers, and so many dollars chasing high-end violin consumption) must there have been developments in improved aesthetic sonic characteristics of violins, but surely many makers have figured out how to make them (simply) play louder.

perception/belief = reality

Before all of the entertainment venues/acts/ensembles were *systematically destroyed, one of the orchestras that hired me to play paid more than a token amount, and it’s music director is known more than locally.

One of the cellists used a carbon fiber cello. As we understand it, those instruments actually do vibrate in order to amplify the sound of strings vibrating.

No one has ever said anything to them about that instrument, and they were certainly never sent home - due to bringing and using it.

two weeks, to flatten the curve

There's one of these ALCOA basses, painted brown, for sale somewhere online at $10K. From what I can make out, they sound better than you might think, but not exactly the same as any kind of wood bass.

I straddled one of those (no bridge nor strings mounted...painted to look like wood) and took it out on Green Lake (Interlochen) late one night, about 45 years ago...

Two years ago I purchased a 36K to replace my 14K, both from the 60’s. Why have more weight on your shoulder (which is on top of your lung) than necessary, right?
No 2 instruments could ever be alike, but fortunately Conn was pretty consistent in making quality instruments during the Elkhart years, so at least that wasn’t an issue here.
On recordings no one ever heard a difference other than that there was a little difference (go figure). The difference is in how they feel. The 36 feels more nimble but I tend to work harder in larger ensembles. I’m certain that’s more of a perception thing from behind the mpc. Also important.

Hands down, I have never enjoyed playing a tuba made from red brass. They “feel” like they absorb all my input, thus I work harder. Again: it’s perception from behind the mpc. I’ve recorded with a red brass Cerveny oval baritone and also with an Amati B&F yellow brass. I like the Amati better but for the life of me I have no idea which one I played during the professional (as opposed to iPhone) recordings.

There’s been some great research done with carbon fiber trombones. Like has already been mentioned, part of one’s perception of playing is transferred physically through our body (bones). And also we as brass players are not used to hearing how an instrument responds from behind the mpc when it isn’t made of brass. So companies like Butler trombones have busy research where to put the real brass, and how much, so as to compensate for what we are want to hear and feel.

That’s my experience to date.

With fiberglass sousaphones (as the sound bounces through the two elbows) I actually HEAR a subtle "baaaoou" sound (from bouncing in a particular way off the plastic surfaces, I believe, but not really from the composition of the material).

Of course, we're all familiar with brass sousaphone bell "after-ring".
