I think the title says it all, right? Currently I own Yamaha 250 Student Model (basic, run of the mill beginner Clarinet) with the 4C mouthpiece that came with it. Lately I've been really airy, and the sound quality has just decreased over time. I was told by a judge at a local solo contest to look into getting a new mouthpiece. In fact, I want to get a better one. But what should I choose? I've been told Vandoren, or Gennusa, but I don't have a clue what to look in to. I want a mouthpiece that will offer a wide range of notes with nice sound quality all around. Basically I want to start to transition from beginner to intermediate. I currently play on Vandoren 3's (the blue box) Nothing fancy really. But, I think if I could get a better mouthpiece, it might make it easier for me to move up to a harder reed. I'm looking to attend Pittsburg State University in the spring or fall semester of 2015, (by that time I'll have completed BCT and AIT for the Army) and plan to use my money earned from Basic Training to purchase a quality wooden Clarinet for chamber or symphony use. I plan to keep my Yamaha for things like marching band, or as a back up, and want a quality mouthpiece to go with it. Any help is greatly appreciated!
