At our school, we are playing a piece called "Metal", composed by Brian Balmages. The percussion part denotes the crotales and glockenspiel playing together quite often. TThere is a major problem with this, because our crotales are incredibly out of tune. Even playing 2 notes within itself such as an octave produce beat, so I know that it isn't a problem with the bells. For those of you that don't know what crotales are:
I am unsure of how to deal with this, because I don't think that my school would allow me to shave part of them off, because too many things can go wrong. And if the note was sharp, shaving can't help in that case, because shaving will make the note go higher. So to fix the pitch of this beautiful instrument, I need an alternative method of shaving them.
