| . The whole idea is to
NOT change the aperture size. You will need to increase the force that
you use when you contract the muscles around your mouth to support the
increase in air speed/volume. But, the end result is that you have
hopefully done everything necessary to NOT change the aperture size. If
someone tries to push you over, you push back (Newton's third law of
motion). The point is you *compensate* to remain standing. The same
thing can be done to NOT change your aperture. Basically you use the
muscles in your face and the abdominal muscles to play the trumpet. The
more you rely on your abdominal muscles, the easier playing will be, the
more power you will have, the higher and lower you will be able to play,
the better your pitch (constant) and you won't get tired. Increasing the
lip tension will usually cause problems (poor sound). I said USUALLY!
So, don't cry and start screaming if you are the one in 1,000 that uses
your face to play and you play well. Again, think of a water hose. It's
the same thing. You can't argue with physics. Air and water work in the
same sort of way. Just don't cut the water down (keep the flow of air
constant as you play). Don't try to rely on your face to do the work!
You will only get *so* far with your playing. Set your aperture, support
the air with firm corners, and blow like crazy! If everything is in
'order', you will see a difference. However, have patience! You must
get coordinated. Count on it not working at first. The more you think
about it, the more it will make sense. Air speed increases the number of
lip vibrations. The faster the vibrations, the higher the pitch. When
you combine an increase in air speed (more air) with even more air (more
air than you need), the sound will get louder. When you tighten the lips
or press, you are also increasing lip vibrations, but that's more work
and it hurt. You can only press so much before your teeth cave in and
you can only push the lips together so much before they close off the
flow of air.
Good luck!
