I have been playing saxophone for about a week and a half now. I was stuck with the plastic mouthpiece my sax came with until now. I ordered both a Yanigasiwa metal mouthpiece(cost a pretty penny) and a meyer hard rubber. My metal mouthpiece came today I opened it up all excited, put it on my sax ,blew, and out came nothing. Not a sound. I was confused because I was using the exact same embouchure I used on my cheap plastic mouthpiece(which didn't produce an awful sound, it was quite bearable). I found if I put alot of effort I could get it to poroduce a sound, but in doing so my teeth bite down into my lip. Any suggestions? I know it's propbably my embouchure, so please tell me what I need to do.
