I found this publication doing an internet search. Does anyone have an opinion on its contents? Braces and Brass - Studies for Trumpet and French Horn for players with braces One of the authors is named Ron Stoneback and is from The University of Sioux Falls at Sioux Falls, South Dakota. He is the father of the Stoneback sisters who form a trumpet trio. All three girls had orthodontics so I think Ron the father would be an expert in the subject.
