There is only one euphonium player.
The person playing it is sleight of stature and doesn't play particularly heroically, but they play quite well, and there's never any problem hearing them nor hearing their solos.
There are two tuba players.
Candidly, I sort of liked it (though I very much enjoy the fellowship with another tuba player) when the other tuba player had to be gone for a really important thing for one rehearsal. I'm sure it's because I had control of the "tuba" volume and the phrasing. I really don't feel like I ever had any trouble putting out enough sound (as one player) at the height of the crescendos, and I really feel like it was nice not having to whisper or lay out on the super-soft ("don't cover up the bassoons and contrabass clarinets") things.
I've typically seen DC service bands touring with three tubas. I do understand the difference between what I usually do (which is to play in orchestras) and the wall-to-wall playing involved in wind bands...but - when I'm practicing at home - I'm playing wall to wall. ... just as I do when I'm playing in little jazz bands whether it's really loud outdoors or not quite so loud indoors.
Camaraderie is great. I completely understand this, because I have this with the trombone players in the various orchestras with which I'm involved... but do "concert" wind bands really need multiple tubas and multiple euphoniums?
