So, for example, new type of valve is patentable; repositioning a leadpipe or changing the shape of a brace or bow guard is not.
While I tend to agree, I think I can imagine a situation where these seemingly minor changes *might* be patentable. It would require significant explanation - but it seems to me it might revolve around *why* the leadpipe is repositioned or *what the desired effect* of changing the shape of a brace or bow guard might be.
One can easily imagine all kinds of hypothetical scenarios in which such a change "might" be deemed patentable. It is debatable, however, whether a seemingly minor change,
i.e., one that does not involve a radical departure from prior art, *would* yield a patent.
Assuming for the sake of argument that tubas are, in fact, patentable, what new characteristics and inventive steps that cannot be deduced from prior art does the 1291 contain that would qualify it for patent protection?
Well...I would expect these to be outlined (in excruciating and redundant detail) in the patent application. If Miraphone hasn't filed a patent application, then the question is moot.
Given the assumption that:

it is reasonable to inquire what the basis for that assumption is, quite apart from the issue of whether or not the 1291 is, in fact, patented.
Certainly, there have been patents over the years for various aspects of "how to build a better tuba".
Emphasis on "build." New manufacturing processes have been deemed patentable virtually from the origin of the concept of patents, by virtue of their utility, novelty and non-obviousness, as are the individual parts,
e.g., the Saturn waterkey. But those are different issues than the patentability of a tuba
qua tuba.
