Just got an email promoting Callet's embochure lessons. First one over the phone for free. I am well aware that this guy has a great range and tone quality but I have not given his method a try.
I know what he says is in conflict with general run of teaching [espsecially as to tongue placement], but I have heard him play the five plus octaves [this guy is over 70]
Are there any here who have successfully used and would recommend his method?
