Here’s my idea for a way to measure better especially when comparing short bell horns to longer bell horns. Why not measure from the end of the bell but from the center point straight down by the same amount on both tubas then measure the bell circumference at that point. In my mind I’m thinking 18...

I'm sure you're making that up.

sorry...no charts/graphs/numbers (and I respect and am fascinated by them)...but (only relying on observations, memory, personal anecdotal, and the like...) If an ancient Conn 36J is a "grand orchestral" (yes...?? no...??) tuba (am I wrong, that this was the first tuba with that sort of d...

When a tuba is built 7 - 9 inches taller than another tuba (as the CSO York-style key-of-C lap sousaphones are often not much taller than three feet tall...37" tall seems common), the equivalent place in the expansion of the bugle of the taller one (compared to the shorter one) is necessarily ...

Okay, guys. The quarter system was a way for any one company to distinguish instruments in their own product line. All Rudi Meinl rotary tubas are similarly configured, and their dimensionless ratios are sort-of similar. So, the 6/4 Rudi has a bigger bell, a bigger bore, a bigger throat, more volum...

No idea, I've got it from Uwe Schneider but there is only the picture and no text that I could find.

So no debate but probably a typo or a reference to the bore, 21 mm, of the StPete. I mean if you have as many kaisers as Uwe has you´re not going to miss that it is a rather small instrument. I´ve played mine besides to miraphones 190 and it looked ridiculously small. Nobody is going to call the St...

I’m not sure what a “monkey sandwich” is...(??) Maybe, some people - who like to target/shadow selected subscribers, here, and pick random specious arguments about tuba stuff - are ~also~ cannibals...(??) I don’t believe the ~term~ “piggy“ (as a size and shape of tuba) existed a hundred years ago, ...

With the impedance curve you could see if there are any notes that don´t resonate properly or if there are leaks in the instrument. There should never again be a tuba sold without an impedance curve, stop selling lemons. In a casual search, I found no equipment suited to this procedure, nor even a ...

That's not the way stuff works man, you're asking a LOT from humanity at that point. I don't even think most people buying a tuba for their high schooler or grad even know or care 4/4, 5/4, or 6/4. Isn´t this the time of smartphones, youtube... If you want to invest a little time you find a video o...

Shouldn´t everybody known when buying a secondhand car to check the compression, all you need to known is one number and it needs to be the same for every cylinder. That's not the way stuff works man, you're asking a LOT from humanity at that point. I don't even think most people buying a tuba for ...

There hasn't been and isn't going to be any such scientific system of measurement in our lifetimes, so we're just going to have to hold off on issuing citations. That is also because the customer doesn´t ask for it and nobody learns the customer what to ask for. I can think of three curves that cou...

I’m not going to get involved in the chest puffing nor technospeak, but there is a size designation for short (usually rotary valves) tubas with relatively fat bodies and not-the-largest bell flare diameters: “piggy” Originally, the term pertained to one model made by one manufacturer, but - since ...

There has to be an agreed upon scientific system of measurement. Imagine if your system of determining tuba size was how the Police determined speed on the highways? There hasn't been and isn't going to be any such scientific system of measurement in our lifetimes, so we're just going to have to ho...

Violin, viola, cello, and bass size designations actually refer to specific body/neck lengths. Such specificity can never be assigned to tubas. It could be but a tuba is much more difficult to measure. The question is if it is useful. An pro player seems to mostly decide himself which tuba he plays...

When both Bb and Cc are pure conical the Cc will look fatter because it has less length to get to the same bell size (asume for both) but the Bb will have 10 percent more volume. Depends on the comparison. The more common C version of that tuba is very likely built on the same bell and bows, and sh...
