+1 - Ok the trumpet isn't like weightlifting? high notes are easy - it is just good breathing, etc. ((so in a couple of months I am going to my old high school and revolutionize their music program -- all of the trumpets are soon going to play everything from the low F# to the double high C's -6 spaces above the staff - with ease -- cause after all high playing is just good breath control - and it's easy!!!!!!!!)) So I agree with the quoted posts because --- at some point you need to strengthen the embouchure in order to hold the aperture in place. I am a comebacker in the 31st month -- I still get soreness, then I rest, the trumpet is still getting better. Mostly near the corners, near the jaw -- the lips are free to vibrate in the center ---and that is the part that I am trying to hold together ---- and it does not happen with a weak embouchure if it does --- then everybody can pick up the trumpet, learn the simple motor controls of the lips, and the breathing --- and wah-lah -- instant trumpet players with a year or two!!!!!!!!!!!!!!!!
