Manny- I just finished my first lesson with a young trombonist who has asthma. Knowing that you've worked with Mr. Arnold Jacobs a few years back, would you maybe share some breathing excersises I can show her to help build lung capacity? (She breathes nearly every other measure). Also--a bit of history, pedagogical trivia or whatever--I found this book in the office where I teach my lessons...I was wondering if you or anyone else has ever heard of it: Lubik-Szodi (with 2 funny lines above the "o" I can't duplicate) Trombitaiskola. It's quite an old copy..2 parts, and the languages (it's in 2) appear to be either Russian (some slavic language, anyway) and German. It show photos on how to hold a trumpet......a rotory trumpet. Anyone?
