        Actually, Rune, what you may be doing is either using too much pressure, or closing your teeth, or allowing your lips to collapse into the bowl...

        The point to remember is that this procedure can be very subtle in application...Remember when you first started to write how you would write in huge letters, and perhaps use a huge pencil....

        The same process occurs in many types of learning, where the gross(large) motor skills are the first to be acquired, then increasingly greater control is gained over smaller and smaller muscles, until finesse is attained....

        Sometimes, the major difficulty with learning something new, is that we tend to exaggerate the process, and if we back off a bit, we find that we are more capable than we had at first realized....

        It's been my experience in teaching that trumpeters, particularly *experienced* ones, tend to have the capability for anywhere from a fourth to an octave more range than they have utilized, mostly because of wasted effort....

        Remember, it is FASTER air, not MORE air, than enables the playing of higher notes...Sometimes, a three step process can help *make it happen* as far as range is concerned:

        1. Center your chops.(and concentrate on *closing* your lips)
        2. Support the air with torso muscles.
        3. Pull the horn slightly AWAY from your face...

        Another thing that you might try is taking a deep breath, then expelling most of that air before you play in the upper register...You may be very much surprised at how little air it takes to play in the extreme upper register, even at louder dynamics...
