Yeah, I knew I was leaving that one open....I just thought it would be turned back at myself. And, thank you. You've identified what I'm trying to say. Basic Intermediate School (notice I don't say "Middle School") Anatomy.....(normal) Breathing is Involuntary. Trumpet playing, and therefore breathing techniques for trumpet playing is Voluntary. I don't know about the rest of you, but I will use the Voluntary breathing techniques taught to me by Mr. Seagull, Ms Jan King, and Mr. Simmons, and all the authors of all the books I've read, to perform the Voluntary acts of singing and trumpet playing. [Edit] Oh and, thank you. Hopefully my Involuntary systems won't crap out on me. It would be a bloody drag to have to remember to breathe 24 hours a day.
