Knowing what we know now...

Sousaphone design that spreads weight to both shoulders.

That stick supporting the bell is going to get in the way on the football field! Maybe put a wheel on it.

Can we take the toilet seat tuba and fold the bottom bow down over the back? So one doesn't have to worry about balance issues? It looks like it's going to fall over if you were walking around. It also seems like having both arms so high up would become tiresome.
Or, as I proposed in the last thread, put the entire tuba in a backpack, with only the valves and lead pipe up front.
And as I recall someone else proposed putting the valves in the back also, and controlling them remotely via bicycle brake cables.

Actually, I think rounding it over your back would lose the leverage gained. These are actually (usually) very well balanced, with the back bow acting as a counter weight; otherwise you'd be continuously bench pressing the thing!

[jacobg]

I realize that the toilet seat tuba might seem well balanced, but ponder for a second:
If someone asked you to carry a weight of 15-40 lbs, in any form, for 3 hours, what would be the best way to do it?
Isn't this exactly what outdoor backpackers have to do? And don't they choose to carry the backpack with two shoulder straps, loosely attached to their backs, with a frame that touches their butts, and a strap around their waist?
I'm using armchair ergonomics here, but it seems as if the butt acts as a third point to distribute the weight, and your upper back (rhomboid and deltoid) makes for a stronger base than the trapezius muscles adjacent to the neck.

This discussion actually starts my thoughts down the path of building a backpack-like frame and straps then modifying a helicon/sousaphone design so that the entire instrument hangs off of that frame with the COG at waist height.
Adjustable straps are necessary so that the bell will fit above the player's head regardless of height (or so that the instrument body isn't below the player's hips for marching. With adjustment to the straps, a piano bench should be comfortable (no back interfering with the tuba).
Start with a Helicon with a lengthened mouthpipe. Rotate the valveset as needed for ergonomics.
Two options for the bell:
1 - Stay Helicon. Bell under the left arm, pointing forward. Not ideal for sitting in a chair in a group rehearsal, but should work fine on a marching field (as long as the bass drums aren't incorrectly placed).
2 - Modified Sousaphone/Recording Tuba. This time the bell needs a taller section between the gooseneck at the top and the right angle at the body. Make it tall enough to place the bell over the player's head (centered). This one's also tricky because of the length of pipe going up the player's back.

The design for bell option 2 may end up looking more like a twisted open paperclip with the final wrap going around 1 side to the bell behind the player before heading up. It also allows the player to put the instrument on from 1 side (clipping into the frame) instead of having to lift the entire thing over their head.

I'm pretty sure Yamaha already made the electronic trumpet.

I have an early 1970s version Steiner EVI electronic instrument (pre-MIDI) that sort of works, but there were a lot of ergonomic problems with it. Having just three key switches required another controller to set the octave, that is the big round rotating switch. It can play in tuba range as well as higher, but it never really seemed to feel right to me.

I haven't tried any of the later versions that are still in limited production...

Maybe something like this? (Sorry for the small image, but there are more views at http://www.fanfarelesnob.com/index2.htm )

Actually, that's pretty close.
If there's a way to flip the bell so that it's not around the player's knees, I think that might work. Everything from the circle up to the mouthpiece is about what I was thinking.

[jacobg]

This guy has managed to create a 3d model of individual components of a tuba.
The parts can then be combined into a tuba of any shape.

How about an adjustable/flexible leadpipe? If you like to rest your tuba on your chair, the mouthpiece often hits us in the nose or the chin. If we are downstream players, the mouthpiece often arrives at our face at the wrong angle.

So we go through all kinds of workarounds to raise or lower the tuba.

Or we raise or lower the leadpipe.

Or we change the angle of the leadpipe.

None of which is inexpensive, easy to do (or undo) or ideal.

If only we could just turn a dial (or something like that) to bring the mouthpiece to our face at the height and angle that works best for us.

[Tubajug]

I like the idea of a 4 front valve tuba having the fourth valve on the thumb.

I toyed with the idea of doing that on a Yamaha YBB-103. The rotor could go right in that tubing before it enters the valve block since the leadpipe/main slide enter the bottom of the valve block.

This already exists for the sousaphone and would be quite easy to modify to work on a standard tuba.

At what cost to intonation and response? Modifying and shortening the leadpipe to accept such a mechanism again wouldn't be cheap unless a do-it-yourselfer took it on.

It's a mod I'd personally love to see. I have a fairly short (and wide) torso, and I'm tired of mouthpieces being at nose-to-forehead height when resting on a chair. I have to sit on the front of the chair and let my legs hold the horn. I haven't managed to find a tuba stand/chair combination that doesn't leave me with backaches.

A flexible or re-angleable leadpipe would do wonders for me. Having a tuning bit on my old 25J made life much easier, and a flexible pipe would be even better, as I need the mouthpiece to be low and angled down a little

[J.c. Sherman]

An adjustable lead pipe would be a relatively easy design, with little compromise in response or openness. The main "challenge: would be the receiver support, but not a prohibitive challenge (I have a design in my head).

Martin and Conn both messed around with the bit system to relatively, if not modern, effect. But it doesn't allow a huge height adjustment... just about 1.25 inches or so.

[Donn]

Aren't leadpipes thought to be critical to a good tuba, small details matter, the slightest dent ruins the whole tuba, etc.? Could the articulated leadpipe play a significant role in the sousaphone's generally undistinguished reputation for fine tonal quality?

Without a doubt.

[Jack Denniston]

Thanks for all the responses to my flexible leadpipe suggestion.

In my case, I'm noticing that when I play my old detachable bell King 2341 (which I love otherwise) I get a sore nec,. I have to scrunch down and point my face up to get the mouthpiece to address my face at the right angle (I'm a downstream player) and I have to hold the tuba up on my legs instead of resting it comfortably on the chair. I also have a king sousaphone, so I tried using one of its tuning bits, but it didn't fit (too big). Even if it did fit, I think it would cause the tuba to play flat (I already have my tuning slide pushed clear in).

So, while I like the idea of using a tuning bit, I don't think it's quite that simple.

Other thoughts?

[Art Hovey]

An idea that was tried but did not catch on.
Too easily damaged.

If your leadpipe isn't right for you but you like the tuba, get out the torch and move it.
You'll be glad you did even if it leaves a scar on the tuba.

[Tubajug]

I'm curious, when you guys say it's easy and rather inexpensive to raise/lower a leadpipe, what all is involved? Do you remove the leadpipe, fill it with pitch, cerrobend, etc. and rebend it? Inquiring minds would like to know.... Thanks!

,,, <SNIP> ...
I will note, however, the originality of the "Orenophone". A very cool, probably more flexible instrument ergonomically. It's the most innovative layout since the King Pit tubas.

After reading this while looking for something else I stumbled upon the "Antoniophone", perhaps precursor/prototype for Oren?


Which in turn led me to Steve Dillon's video blog about this class of instruments.

I've been brainstorming as of late, and I've come across a few things; The tuba player for Mnozil Brass has had a 3+3 F developed by Meinl Weston, if memory serves. I thought about making one, but... nah. Ain't got the budget. I also thought about making a 3+1 compensating euphonium-esque rotary F tuba, maybe CC with 3 double-rotored Hagman valves and an axial flow valve under the thumb leading back into the set of double rotors. The Hagman valves could corkscrew out, too. I'm thinking it could lead to uniform pipe size, rather than having an enlarged 4th and 5th for a freer blowing horn. And space saved by the Hagman corkscrew thingy, you could compact these horns, so cases would be smaller. On top of that, you could have a much more reasonable bore size, and still get that open blow. The parts would be a bit more expensive, and it doesn't help that I was thinking of buying, say, an Adams Custom (for, hopefully, better intonation tendencies) or old York bell to stick on it, so this would be a seriously expensive pursuit. In terms of leadpipe angles, I've got nothing; I don't really put much thought towards that aspect of the horn. Any feedback on this would be appreciated; I'm totally working off of my mental image of the moving parts on this one. EDIT; I haven't actually read through the article as of yet. If this has already been covered in any fashion, that's on me. I sorta got a bit overexcited, starting foaming at the mouth, and began to key out my latest brain-child in the most frenzied manner possible.
