I rarely play band concerts, but I'm trying to offer some useful "F tuba" insights...
...In the past, my ONLY tuba - for several years - was my F tuba, so I didn't just practice recital pieces and Berlioz licks on it, and then stick it back in the sack.
NONE of them may be of any value, so (if everything below ends up being full of beans) just please ignore all.
Not-huge symphony orchestras are often around sixty players.
If anyone is under the impression that a bunch of good string players don't make a bunch of racket, that person hasn't played in an orchestra.
...Stand next to a good violinist who's playing through misc. passages...ie. LOUD !!!
How good are medium-size-city per-service orchestra string sections, these days?
With awareness of the dynamic - ie. the glut of conservatory graduates: They're semi-amazing.
Sixteen (or - certainly - twenty) good fiddle players can make a TON of racket (and more than that many clarinets, because of the shimmer).
Orchestras only feature one tuba.
Particularly in pops arrangements, the tuba tends to be quite prominent, and a few basses - playing along with the tuba - isn't probably not as much help as one more really good additional tuba.
I could take my F tuba to most any orchestra concert and play most any (and with a few exceptions) literature with it.
It's often more "fun" to take a large tuba, so I use it when the technical/velocity demands (at a particular concert) are less...and sure: other demands on other types of energy (when playing a big tuba) are more.
If I want my F tuba to "bite" less (at top volume levels), I can change that with a medium (rather than medium-shallow) mouthpiece.
old saying:
"The basses [tubas] should be felt, and not heard."
The overwhelming majority of the time (were I to follow that old adage), conductors/directors would probably look up and ask if I entered when I was supposed to...
...ie. We are expected to put quite a bit of energy into our instruments - regardless of length/size.
When I rarely am forced to miss a series of orchestra services (whether the substitute is a former/current military musician, college teacher, graduate student, etc.) I hear something like this from the trombones (every single time), "The music director had to encourage them to play out several times, but they finally put out enough sound."
one last thing:
When some concerts are officially/unofficially videoed (and regardless of the quality of the microphones or their placement) - and there are a few pitches or passages that (it seemed to me) that I may have possibly played "over the top" (yet NEVER "called out") - when I listen to the recordings, the tuba sound - at those specific places - seems to be "just about right".
summary:
Of course, we should play WELL (with musical taste/phrasing, and all of the lower skill sets required to play instruments) but also play OUT...regardless of the particular instrument.
I use my ability to "fade out to nothing" (which I'm pretty good at doing) as a nice musical effect, but - were I to interpret "
ppp" as - literally - "ALMOST nothing", the music director (and I KNOW this would happen) would stop and say, "I don't hear the tuba...(??)".
sidebar:
I have one music director of one orchestra who looks at me before EVERY SINGLE tuba entrance. How cool is that?
