Reminds me of medical procedure I once did. ![[wink]](http://test.woodwind.org/clarinet/BBoard/smileys/smilie3.gif)
I wonder why the reed seems to be in repose even when I hear a sound.

Perhaps we are not able to see the fast reed vibrations that are producing the tone. The slow movment of the reed in both videos might be reed movement we were not aware of. Anyone more knowledgeable of reed physics able to provide an answer?

When the reed vibrates with exactly 500 Hz, while the camera is only capable of 25 frames per second, you wouldn't see a movement at all. (Ever wondered why spoked wheels of those carriages seem to turn backwards in TV?).
I'd attribute the slow movement to some kind of stroboscopic effect, either of the camera or the lamp illuminating the scenery.

They're using a strobe to slow down the action in the same way they do when filming vocal cords with an endoscope so we can see what's going on.
I'd like to see the same thing done with double reeds.

Let's hope researchers pursue this avenue further.....fascinating. And.....per above explanations....just goes to prove again that you can't always believe what you see.

there is a stroboscope read-out displayed in the upper left of the video frame giving frequency and sound level in dB.
It looks to me like the (high speed) video camera is synchronized with the sound wave so that the reed appears stationary. We only see it move when the pitch changes quickly enough for the system to mis-synch with the reed movement.
I note that the reed is not slapping the mouthpiece tip.

I was expecting the reed to be closing against the mouthpiece a lot more as well, so much so that it goes slightly concave.
But he could have used a new reed - the tip is all frayed!

Chris says he wants to see the inside of a double reed...what I want to see is the camera that could fit in the staple or bocal to show us the inside of the double reed...

The size of endoscopic cameras has come down to less than 3 mm.

That's pretty crazy. Is it just me or is the reed moving up and down slowly in the videos? it appears as if the tongue is moving the reed, but as Ben used the analogy of a wheel rotating backwards, an optical illusion?
What kind of camera was used? it appears as if the player was holding the camera inbetween his jaws and playing at the same time, thus the squeak.
Neat idea.
Our inventions are wont to be pretty toys, which distract our attention from serious things. they are but improved means to an unimproved end, an end which was already but too easy to arrive as railroads lead to Boston to New York
