rowuk, this time its not about range, I was just throwing that out there to see people opinions on it. In the end I'm not going to ever sacrifice tone or playing ability for range. Anyway thanks for all the posts so far, I do have a private instructor, (not the best, but once I get a job I'll see if I can change that) and have only had a handfull of lessons so far, but when I first came in he told me not to switch cause at the time I had got the trumpet just the other day. I was under the impression that as you get more advanced you want to switch to a 5c/3c and that it was better for you to go down from 7-5-3 (if you go to 3). From my understanding I thought it was supposed to be a bit harder to play on, but give more control and maybe a bit better tone overall. I just didn't know when you should judge when to switch. I suppose its on a more personal playing level, but I didn't know when the average to slightly above average player would switch after some years.
