Hi there, I'm a comback player, been playing about six months now and things are going very well. I wish to make a career of it, go back to school for music etc. I was wondering about personal sound. There seem to be lots of factors contributing to a person's individual sound. The player obviously, the horn, the mouthpiece, the room you play in. In terms of style, what I am wondering is it possible to change your sound....and by that I mean one's personal sound on the instrument not concerining horn choice and mouthpieces. Or is it something that just naturally develops and that's the way you play and the way you sound. Is it possible to focus on a specific quality to one's individual tone? Say, a "brilliant" tone versus a "dark tone" One of the things I love about the trumpet is it's propensity for individual development. I know I just started back and I may be jumping the gun here. But are there things to keep in mind when develping embechoure and apeture regaurding a specific tone? If I want a really fat sound, is there something I should conentrate on? Excersizes or simply things to keep in mind while playing? I love roaming this website and as a result I've seen loads of really awesome advice and viewpoints. Any opinions on this subject would be welcomed and appreciated. Thanks, and keep practicing!
