Some euphoniums and tubas were built like this, but today, this approach has become highly exotic for all instruments except horns, where it is the norm, usually in a double, sometimes even triple configuration. Some valved brass instruments provide triggers or throws that manually lengthen (or, less commonly, shorten) the main tuning slide, a valve slide, or the main tubing. These mechanisms alter the pitch of notes
Victor Ewald instruments played in Bellon’s quintet and certainly in current times, by such as Canadian Brass. Photographic evidence from about 1912 shows that Ewald himself played in a brass quintet. It is seen to consist of two piston-valved cornets, rather than the modern choice of trumpets; a rotary-valved alto horn, rather than the French horn; a rotary-valved tenor horn, rather than the trombone; and a rotary-valved tuba (played by Ewald himself).
