Sound bar and percussion instrument

A percussion instrument comprising:

• a plurality of sound bars,
• wherein each of at least two sound bars of the plurality of sound bars comprises an elongated member including a surface layer having a striking surface having an elongated shape,
• wherein 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 being an area sandwiched between the striking surface and a virtual surface that passes through a portion where a thickness of the surface layer is maximum and that is parallel to the striking surface, and
• wherein the at least two sound bars of the plurality of sound bars are different in a weight increase/decrease direction along the longitudinal direction of the striking surface in the striking surface side area from each other, or layer structures of the at least two sound bars are different from each other.
