Hi There, I'm new to notion and composition. I have the ear for it but not all the practical info I need. I'm writing brass and reed arrangements for a group of teenagers. Most of them have several years under their belts and some are quite good.

My problem is that I really have no idea what the comfortable range is for your average, non-virtuoso player. Does anyone know where I might be able to find a chart containing such information?

Thanks for your help!
Eric
