i'm not a saxaphone player but i do know that in order to get that high pitched squeel he bites down on the reed. i suggest getting some video of a performance. i have a really high quality video of naked city show that was broadcast on some New York public television station, if i wanted to learn to mimic his technique, i would start there. best of luck, adam morosky original message: Are there any other sax players out there (or anyone else for that matter) who can tell me about same of the extended techniques that Zorn utilises in his player.
