What does everyone think of switching mouthpieces depending on the type of playing that's required? Does anyone do it? My teacher told me he plays a 3c for everything, and I could tell he wasn't fond of the idea, so I just let it drop, lol. However, I have started too switch a very little bit for jazz/pep versus symphonic, although I still doing more of my playing on my symphonic piece. I can play either style on either mouthpiece, but it's easier to have a fuller sound on one, and easier to play in the upper register on the other.
