    Re: upper register problem

    Just blowing does not relate to playing the trumpet. The lips open and close like valves, completely stopping the air (check this link: IWK Brass Research )
    The teeth are also in the way, so that even if the arched tongue did something, it would be cancelled.
    Proper playing finds equilibrium between the backpressure of the horn/mouthpiece and our airpressure blowing. If we blow too hard, the lips would collapse into the mouthpiece cup.
    The only argument that makes sense to me is turbulence in the mouth.
    Whenever I feel blue, I start breathing again.

    Hi Rowuk,
    I checked with IWK and first I want to say thank you for telling me about the site. Unfortunately, while much information is there, I didn't read any data that speaks directly about the topic of air speed and its relationship to the tongue and the oral cavity acting like a valve to decrease and increase air speed. I tried to get in to some of the research papers but a "not found" command came up on the literature. If you have any specific articles that can be accessed and read that would be great. Once again, thanks for the great site.

    Hi Rowuk,
    I did a little lit search and found some interesting stuff as it pertains to air speed and pitch control.

    Here are some of the internet sites both Pro and Con:
    -Excitation mechanisms in woodwind and brass
    -Playing in the upper register
    -Wiki answers how to play high notes on the trumpet
    -Mark Ponzo trumpet solo class lecture 32
    -Allen Vizzuti's book New Concepts for Trumpet pg 144
    -Julia Rose home page notes on technique by Dave Bilger
    -Mystery to Mastery Tongue Aperture Position

    After reading, its hard to argue with the experiments of Bernoulli.
    Intrestingly, when I lip buzz (as with some of the experiments using rubber lips) and change the oral cavity, the pitch does change. Not as dramatically as with a whistle, but is does change. We may be looking at a combination of both aperture and the tongue as an excitation mechanism to be correct.

    Re: upper register problem

    Just a thought.

    When we are forcing air through the small opening in our lips into the mouthpiece and horn we create backpressure. The air in our mouth is being compressed, which takes quite a bit of energy. By raising the tongue we reduce the volume of air that needs to be compressed to the psi level required to overcome the backpressure and allow the air to pass through the lips and throat of the mouthpiece (the smallest points in the horn "system"), thus making the process more efficient. The increased efficency is why we can tell the difference and why we say "it just works".

    The paper example could be thrown off by Bernoulli's Principle which states that a moving air stream has less pressure than a stationary air stream, and the faster the movement the lower the pressure. It has been several years since I have had a physics class or I would try to deduce this one better.
