Well, obviously I am new to this site, or why would I be posting on this form, right? I just happened to stumble upon this trumpetmaster page, and my eyes lit up. I am by no means a professional, but I do enjoy playing so very much.
I am sure 99.99% of you will either not read this at all, or if you do, you won't really care, but for the .01% that just might, I will tell a little about myself:
First off, I am 23 years old. Been playing trumpet since 5th grade. Not until my sophomore year of high school however did I really begin to try. I became pretty good. 2nd best my soph year, and 1st chair my jr. and sr. years. Now, after high school, I don't have the chance to play as often as I'd like. In my town, we have a "City Band" that performs 6 weeks every summer at the park. Now that I do not have the opportunity to play, I seem to want to more and more.
I just became a father 8 months ago, which put my practicing on hold. Before he was born, I would pull out the horn for one, two, sometimes even three hours a night. I was really getting a lot better.
My worst thing when it comes to playing, is my heavy tongue. I can not seem to spit out the notes fast enough at times, when needed. Also, I am just no good at marches and songs with a lot of up beats. don't know why, I just can't do it too well. I manage, but its not easy, and takes a lot more concentration on my part.
I do not have a fancy horn, or mouth piece. Bach Strad, 3c, and 14c4 mouth piece's. Can anyone suggest a mouth piece that might give me a deeper sound?

I have rambled on now quite long enough. I would really like to talk with many of you, and maybe get some idea's on how to get better, maybe get some idea's on artists, so i can buy some more cd's. I have Louis Armstrong, and Miles Davis and such, but what are some of your favorites? Also, I wanna get my son a trumpet by the time he's 4 or 5, any suggestions? just a standard student horn to start? or maybe something a little better?
