Concert band music question
I've received music for a concert band festival I'm playing at later this week, and of the five pieces i've received three are tuba parts. Some of the notes are off the bottom of the staff -- too low for me to play. Should I just take these notes up an octave, or should I take the entire line up an octave?
...and every one of them knew that, as time went by, they'd get a little bit older and a little bit slower.
