I think I discovered myself to be a "long warm-up" player. I do a basic warm up of lip vibration, mouthpiece buzzing, long tones, flexibility runs, tonguing & slurring scales; approximately 10 min.. Then I begin to perform or practice. What I discovered in my recent practice is that I play most effectivly after 20 or 30 minutes of playing exercises. I wont go on with a detailed discription because I know the professional TMer's will recognize my experience. I'm looking to get some input from TMer's that do long warm-ups. All responses are welcome. Do I actually have to take up to 1/2 hr. of vigorous playing before performing a night of music? [WILL I BURN MY LIP OUT FOR THE GIG?] I'm a returning player making new discoveries after many years. I'm needing a little hand holding, and advice.
