I'm new to trumpet. I'm also old to start learning trumpet, a middle age man ^_^. I got myself a 1959 olds ambassador trumpet to start 2 weeks ago along with my daughter. I have an olds 3 to statrt. And it seemed the mouthpiece is small for me. My lips can't move freely. I'm learning it just for fun, so I'd like to get a bigger mouthpiece say Bach 1 1/2C. Will that be difficult for me to play?
