During Jr. High School Was the only public school Orchestra that I have ever seen. Only string players were in the orchestra. When they needed brass players We were sent over During regular band class, or taken from another class, in order to participate, all of this depended on scheduling, of course. We usually got two or three rehearsals with the full orchestra before a performance. Sorry for the Memory, It, for me was a good experience. The point would be that your brother will learn that the choices we make today will have there effect on tomorrow. Let him do what it is he wants to do. Is there a reason he shouldn't go with his choice?
