i have a question for rowuk...actually 2...(not opinions disguised as questions, but actual questions.) you stated that you (and your students) could perform on any standard mouthpiece. i've known other who could do this, but i have never been able to manage it. within the obvious limits of an internet format, could you describe how this is accomplished? and secondly, and this is related more specifically to the original post; since we are talking about a callet 17 being the original mouthpiece in question, would you consider that within the realm of "standard"? the specs are less than .600 (actually closer to .590) would that consideration have any implications on your answer here, and if so, how?
what prompts the question, especially the 2nd one, is that i have known lead players who played a certain mouthpiece in their prime, so to speak, who were forced to abandon that mouthpiece later in life. it became just too extreme, for whatever reason. ...strad
