Abstract: A sound bar has a striking surface. The sound bar includes: a surface layer having a first surface constituting at least a part of the striking surface and a second surface opposite across a thickness of the surface layer from the first surface; and a base fixed to the second surface of the surface layer. A cutout surface is provided on a peripheral edge portion of the striking surface. The first surface of the surface layer is smaller than the base in a plan view.

Abstract: A sound bar includes an elongated member having a striking surface having an elongated shape. A weight of a striking surface side area of the elongated member, per unit volume of the striking surface side area of the elongated member, changes along a longitudinal direction of the striking surface. The striking surface side area is defined in a range of a uniform thickness from the striking surface.

Abstract: An object of the present invention is to provide a tone plate that can be increased in strength and that can produce the original sound of the material. A tone plate 10 according to an aspect of the present invention includes: a surface layer 1 having a striking surface 1a; and a base layer 2 that is laminated directly or indirectly onto a face of the surface layer 1 on the side opposite to the striking surface 1a, wherein the surface layer 1 is a layer of wood impregnated with resin, and the base layer 2 is not impregnated with resin.

Abstract: A musical instrument includes an instrument main body extending in a first direction, a first protruding portion that protrudes from one main side of the body, and at least one second protruding from the one main side and spaced from the first protruding portion in a second direction perpendicular to the first direction. The center of gravity of the main body is interposed between the first and second protruding portions in the second direction and located in a region defined by the first and second protruding portions. The region has a polygon shape.
