Looking again at the original post and original question, you are completely correct that it's ridiculous for an entire section to play "thumping" bass lines around middle C. It's poor arranging, and I can just imagine what it must sound like. When it's well done, bass lines originally played on electric bass can be quite successfully performed by a section of tubas - the examples are too numerous to begin to mention. It's unfortunate that you're a "guinea pig" in this experiment for a student arranger, but it sounds like that's part of what you signed up for. I think it's nice that your school offers such a vehicle for students wishing to learn the finer points of arranging for band.
It sounds like you've expressed your concern to the arranger and were shot down. What is left to do but lay out on this particular tune for the greater good? Let Joe have his solo, and you can just fake it or whatever to make the piece work better. Most of us have been there, done that.
I'm still bothered by your use of the word "most" in your posts:
- "Most" arrangers are quite good, and do understand that you shouldn't write rock-style electric bass lines in the high register for a section of tubas. This student is apparently not one of them. That said, one of the ways a successful arranger learns the craft is by hearing the things they write and, hopefully, taking note of what works and what doesn't.
"Most" tuba players wouldn't pick up an electric bass part and play it in the notated octave - "most" of us are savvy enough to know that bass parts are notated an octave higher than they sound.
I seriously doubt that "a lot" of tuba players can't read a part down an octave without missing accidentals and/or rhythms that they wouldn't have missed anyway...it's simply not that difficult.
