Thanks for the info guys! So--how important is it to be able to play way below the normal pitch for the mouthpiece? I can get an octave on my tenor piece if I start way up at A, but there's no way I can go all the way down to G from G (not yet anyway). Anybody else do these kinds of exercises? I also like to practice slides, growls, etc. on my mouthpiece and neck. Leaving the sax out helps me to focus on the tone production mechanics (I think). I figure if i can get a decent tone on the neck, the horn would probably sound good too? Lastly: I've often wondered if the tone played on the mouthpiece alone can be used to diagnose mouthpiece design issues/characteristics? The tone that I get on different pieces is very differerent. eg: can you hear if the baffle is uneven by the mouthpiece tone etc.?
