Hello all, This could be a long post, so I'll give the Reader's Digest version.......... I played in church last Sunday Was approached by High Schooler with range problem ( no double C yet? ) I gave simple safe answers as I don't pretend to be a teacher Kid insisted there was something very wrong with him I let him play a chromatic on my horn, air only, no tongue The kid found he does have decent chops I told him play chromatic again using tongue Kid starts getting weak at the C and dies at G I tell kid to get good teacher Kid asks me for more advise / solution I tell kid to get good teacher Kid leave upset I leave a little upset not knowing how to help What should I have done? I have no idea what's causing this kid's problem, how did he expect me to help him fix a problem I don't know the cause of? Thanks!
