No, frankmike, I have just described a part of the Sam Burtis approach in a quite clear and untwisted way. Where do you people get this stuff!!!??? Here is a quote from an early page of Maggio's "Advanced Studies" book as written by Carlton MacBeth. Now...I am not going to get into a pros and cons argument about Maggio's work. Enough successful players used his approach for me to say that it had value. But what I am doing has nothing whatsoever to do with any of the above. My approach produces an embouchure...a set of embouchures, really, a well-connected set...that is most efficient for any individual player no matter whether his or her initial middle range lip setting is 2/3 upper-1/3 lower, 7/8 lower-1/8 upper, 1/5 upper-4/5 lower (By the way...what set of calipers would one use to measure these jive proportions?) or any other setting one could possible imagine. Nowhere in the several Maggio books that I have does he mention singing overtones as a way to find the chop. And you write that I just "used [the] Louis Maggio method and explained it in twisted way!!!???" Nice. No, I am on my 40+ years hunt of finding a better way to play brass instruments. Whadda buncha maroons some brass players are. Thanks for the input. Now I'll go back to practicing my six octaves. Later... S.
