Abstract

See full text

A soundboard for a piano comprises three plies of wood bonded together, the front and back plies being of substantially equal thickness and the center ply being of a thickness greater than the sum of the thicknesses of the front and back plies. The center ply comprises a plurality of elongate boards each having a preselected curvature from side-to-side, these boards are bonded together edge-to-edge with the curvature of each board in the same direction to form a composite board having a substantially continuous curvature, concave on one side and convex on the other side. Consequently, the assembled, three-ply soundboard has a curvature imparted thereto by the center ply.
