Hi, I don't know if anything like it even exists, but are there such things as a stand up solo's or duet's with band accompaniment for beginner bands? Or at least pieces that feature particular instruments? To give an idea of standard, they're currently making light work of "The Cathederal Suite" by Stuart Johnson. I'm facing a problem that I'm sure other instructors face; you've got a few players that are ahead of the rest, and you're trying to keep them challenged but don't want to leave the others behind. Any suggestions?
