Wayne's experiment is excellent. First suggestion: place a dowel up the clarinet
to reduce the volume of the cylinder. Second suggestion (and I should try this
myself) -- place a cardboard disk with a small hole in it between the clarinet
mouthpiece and the barrel.

I am wondering how much of disparity in experimental results is due to having a
very small mouthpiece opening with the double reed setup going into a relatively
large cylinder. Perhaps this arrangement actually is the equivalent of a cone.
The dowel might reduce this effect by reducing the volume of the cylinder.
(However, it also increases the surface area. Oh well, more confounding
variables.) Blocking the end of the clarinet mouthpiece might duplicate this
effect with the single reed setup. Perhaps I am saying the same thing as Mark,
who posited that "the cork and tube create a discontinuity which cannot be avoided
in a simple experiment". .
