kdk,

I'm sorry for the error in my post. I meant to say density, not strength.

When you work the math for "lumps" of things vibrating, you can often come up with a formula for frequency of vibration that breaks into two factors. The first is the square root of the ratio of stiffness to density, and the second addresses the "lump's" geometry. ["Stiffness" is Young's modulus, and "density" is mass/volume modulus.]

Stiffness/density is specific stiffness, and is probably what the designer of a synthetic cane for use in reeds is searching for --trying to match the natural cane. Interestingly, specific stiffness is about the same for all metals. Steel is both 3 times as stiff and 3 times as dense as aluminum.

The current champions for stiffness/density are composites of boron or carbon with a matrix like epoxy to hold the fibers together. I'm anticipating the marketing of carbon fiber reeds.

interd0g,
On biting. I think it is a natural result of the player trying anything to make the altissimo speak. You bite, and sometimes the note comes out. I've been trying to break my biting (and half holing) for a long time now.
