The present invention describes the use of nanophase materials, chiefly aluminum, in musical instrument construction. Nanophase materials have constituent grains that are substantially smaller than those of conventional materials, imparting greater strength and deformation resistance. Aluminum has excellent acoustical qualities for making musical instruments, but its use was previously limited due to material weakness of pure aluminum and due to unfavorable, metallic sounding acoustics of aluminum alloys.The present invention also describes the use of aluminum composites in musical instrument construction to further strengthen the material composition used. The use of nanostructured materials in musical instrument construction, e.g. to make soundboards, provides exceptional, premier acoustical qualities as well as great strength and durability.
