A revised view on old small Eb tubas and mouthpieces

During the thread started by me, but really initiated by questions from another list member, about the optimal choice of an American cum CC-ish sounding Eb with certain playing facilities making it easier to play, I mentioned my doubt about the adequacy of older small bore Eb tubas being played via the original mouthpieces or their modern equivalents: large bassbone mouthpieces.

This morning I took out my 1870 Besson non-comp 3+1 Eb and flushed it with hot water in the bathtub. Not too much dirt came out, but another problem surfaced: the piston springs are too sloppy. The pistons are not shot, but could be tighter. The alignment probably also could be improved by a few felt shims/rings/or-whatever-you-call-them.

With that in mind I did a playing test making sure that the pistons didn’t stick midways. Nothing about virtuosity, not really about intonation either. Response was the main target of the test.

I used my Yamaha Yeo signature mouthpiece, which I use on my euph and Bb bass bones.

The result was amazing despite the fact, that I am not really in shape playingwise. A, hopefully temporarily, constricted/cramped nerve in the diaphragm area doesn’t inspire playing that much.

But this 135 years old tuba revealed a resonance especially in the lower 2 octaves down to the second pedal, which surprised me. The upper 2 octaves up to the 8th partial took some more care to get, but then my breath support obviously doesn’t take too much resistance right now.

In a way this lightweight instrument mostly reminds me of my YEP-641 euph, even if the latter is a heavyweight. The 1870 Besson has this amazing aliveness, resonance, and vibrancy, but it is neither CC-ish like the Besson 981, nor does it approach the sound of a bass trombone. I think it is the epitome of what older Brits would call a single Eb bass.

And then it has some smallish measurements, which truly surprised me, when I finally applied my calliper and ruler:

The bore is 0.634 right from the 4th valve placed in the leadpipe through the 1-2-3 valves, which are placed after the main tuning slide.

In style with some other old Brit tubas, the 1-2-3 slides are placed on the back of the body.

The bell diameter is only 13.78"

The weight is only 5.8KG

Maybe I missed stating my point:

An unlikely small mouthpiece may work with a small tuba.

And my big question is:

How can an instrument with such a disproportional length of small bore cylindrical tubing actually sound like a tuba?

A couple of years ago, i purchased a couple of Marcinkiewicz contrabass trombone mouthpieces (106 and 107) for the purpose of playing around with an old Eb tuba with a super small shank.
They're around the same size as an old York 18 mouthpiece I have.

They used their ears to build them, and were not as easily swayed by what the "scientists" (who knew a lot less about acoustics, back then) told them

For example... take a look at the differences between Eb and BBb mouthpieces (which were much smaller in 1924 than they are now; they look about euphonium size inside!... )

Please check your link. I came up with error messages when I tried to hyperlink.

Sorry; they do, indeed, seem to be gone/offline now. The image was from an H.N.White mouthpiece catalog from 1924. It showed the relative sizes of the mouthpieces as cut-in-half shapes.

Yes, I also looked at the site to get information in the past. I hope they are able to come back! In the meantime, try http://www.hnwhitekings.com

Right now, only information regarding trumpets and cornets, but good information nonetheless.
