Hello, so I guess I will give you some background information for a better answer. I am currently a Trumpet player in my schools Jazz band, I am a Junior, have been playing sense 5th grade so 8 years. I have a Getzen Eterna 700, and a Barrington Flugelhorn, I have Jo-Ral straight mute, soon getting a cup mute. My mouthpiece for trumpet is a J. Marcinkiewics 3/5C, and a Bach 7 FL. I just had a concert with the Diablo Valley College Night Band, and I wanted to be just like them, but I have nothing to help me to get to that point. Funding my own hobby for the small things like books and what not is difficult with no way to get a job. So basically I am asking, if I should save for something nice, a warm-up, and some range and tech. building exercises. If so I will save to buy books just have to do some chores =D thank you for all your help.
