So I have been playing trumpet for about 8 years never really had a huge problem buzzing on the mouthpeice. But now it seems that I have to put a huge amount of effort into playing on it. I have been playing a lot more than ussally lately but my tone on the trumpet improved. Am I playing with two different embrochues? Im going to have my teacher check it out when I see him next. Should I be concerened because the last thing I need to to rebuilding new bad habits.
