You got it! Yay! (Except for the legs of the main tuning slide, of course, and sometimes the whole tuning slide, as with the Miraphone 186.)tooba wrote:If we go by by that standard, then there is little to no true cylindrical tubing in most rotary tubas except in the valve slides.
There are exceptions to any set of samples, but that doesn't necessarily lessen the accuracy of the characterization of those samples, or the accuracy with which they represent the population.
And, yes, I own both. Furthermore, I've measured them.

(By the way, Joe's comment on the topic is important. He is saying that the higher the pitch of the tuba, the more valves one needs to play a given set of notes, particularly low notes, in tune. It's hard to play a low F on a C tuba with four valves, and that is a common note. It's easy to play on a four-valve Bb tuba. It's easy on an F tuba, too, but the Gb right above it may require five valves on that F tuba, and still be out of tune. But it only takes two on a contrabass. It's also a common note. Many who have five valves on Bb tubas say they'd struggle to play low stuff in tune without them.)
