I'm a newbie to trumpeting. About to start lessons. I wanted to know, what are some good types of mouthpieces, which are good for what styles, which are "all purpose", and if there are some that are easier to play on. Basically, my new trumpet doesn't have a mouthpiece with it, so I was wondering what I should go for. I plan to use the trumpet to (in the future) become a pro trumpeter, so I'd like to buy a professional grade mouthpiece (not a student model). Can anyone help?
