My 13 y/o daughter has just joined her school concert band. But as they don't have any bass parts written out, the leader said "just play the tuba parts". Problem is, tubas go down to B and C all the time - but her DB doesn't. It seems to me a bit rough to ask a young player who's only just getting the hang of reading to simultaneously transpose an octave higher whenever the notes hang that low. What do you think? Is this a normal sort of problem, or should we insist on some DB parts written out for her, or should she make lotsa pencil marks (against instructions) on her charts? Unfortunately I don't think I'm capable of writing out new parts for her.
