Teeth . . .
I’m a professional trombone player in the San Francisco area & I teach private lessons.
Having spent a few years in LA in the early 70’s & having the good fortune to play with some good studio brass players, I saw a wide variety in facial physiologies.
I’ve read your web page on embouchure & I’ve heartily recommended it as a fundamental guide for fellow professionals & also my advanced students.
I noticed through the years that many brass players who seems to have “natural” power & high range have perfectly even teeth (or have had them re-sculpted by a knowledgeable orthodontist), and in some cases, they have a slight underbite.
* And, of course, they are focused & practice! *
Question: do you view a slight underbite as a natural advantage?
Could be, but then since the lower jaw would have to be pulled back it might not be comfortable or natural, I wouldn’t want to say for sure. I think you have to take it on an individual basis.
