1. A percussion instrument, comprising:
a top planar plate, including a first end, a second end, a front side and a rear side; a bottom planar plate having the same dimensions as the top planar plate, being spaced apart from the top planar plate, and being oriented parallel to the top planar plate; a front side plate spanning between the top and bottom planar plates, and extending from the first end to the second end of the top planar plate; a first end plate spanning between the top and bottom planar plates, and extending from the front side to the rear side of the top planar plate; a second end plate spanning between the top and bottom planar plates, and extending from the front side to the rear side of the top planar plate; a rear plate spanning between the top and bottom planar plates, and extending from the first end towards the second end to define an acoustic gap spanning between the second end and the rear plate; and a plurality of spaced-apart welds disposed along an intersection of the front plate with the top planar plate. |
