I have Larry Teal and some other books, and I can do harmonics using low Bb and B, but can't seem to get high F#. I can tell that the proper fingering is the traditional alternative F# fingering using the Bb/A# key with front F key. But I'm not sure how much you have to tighten embouchure and exactly how, and what tongue position will work. Do you tighten up on the reed or loosen up and tighten the corners of your mouth? And does the tongue position mimic one of the positions you might use for harmonics?
Thanks for any suggestions.
