Discussion Used widely in piano, harp, violin, and guitar manufacture, its high strength-to-weight ratio and regular, knot-free rings make it an excellent conductor of sound. For these reasons, the wood is also an important material for sailing boat spars, aircraft wing spars, and the nosecones of Trident missiles.
