    When I saw the "Airmen of Note" last week, during the whole performance, the lead only played 2 DHC's. They were perfect! There were also a couple B's, Bb's, and A's. MOST of the time, they never got above a high G (and all these guys could scream). Point is, they played everything musically (even they high stuff). Testosterone was absent but musicianship was present and accounted for.

    It has always been my experence that testosterone is absent when it comes to airmen.

    my name is ken -- I played an F scale to the high F last night --- it sounded great --- so I quit my practice and went to sleep. I did not try any notes higher than the F (ok, maybe a G, but it was thin and sharp) ---- but I did not try to hit a dubba C. I am doing well, but it is a one day at a time struggle!!!!! today, I will try NOT to hit a dubba C ---- thanks for your support!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Mark,

    while it is true that the acoustic length of the horn changes with frequency, the length works the other way around. This is very easy to measure as the directivity of the higher frequencies happens to correspond with the flare of the bell and decreases the higher that you go. Most all horns work this way.

    If you spend some time researching horn theory, you discover the highest resistance where the efficiency is greatest. That has NOTHING to do with the blow. Expelling air is low frequency - like direct current and is unaffected by the standing wave in the horn. Resistance goes up with frequency because the lips are opening and closing at a faster rate and have less "leakage". In addition, most players use more pressure up high which clamps the lips shut. This has all been explained so many times I am surprised that the myths keep coming back. When things that don't line up with physics are claimed, I really question how much research went into the oiriginal assumption.



    My problem with some of the younger members is their need to post like they know what they are talking about. I really respect people willing to ask intelligent questions. Those people are valuable because BS is hard to defend. On the other hand, the idiocy of trying to "belong" by playing expert accomplishes just the opposite. Once you teach and perform for a bunch of years, telling the difference is easy. The young ones don't have ANY of the survival techniques and post like indestructability exists.
