Abstract
A reed construction for a musical instrument fabricated from a plurality of fibers combined with a binding agent and a filler material of lower density than the binding agent, so as to produce an acoustic impedance comparable to that of the natural cane reed.
Claims19
A reed for a musical instrument, said reed having a longitudinal axis and comprising:
- a plurality of fiber means oriented substantially longitudinally of said reed and arranged in generally uniformly spaced-apart relationship cross-sectionally of said reed;
- binding means combined with said fiber means for securing same, said fiber means having a modulus of elasticity that is greater than that of said binding means;
- and
- filler means substantially uniformly dispersed in said binding means in regions between said fiber means, said filler means having a density less than the density of the binding means;
- said fiber means, binding means and filler means having relative proportions selected to produce an acoustic impedance of said reed at least comparable to the acoustic impedance of natural cane.
