The metal body has a general hourglass configuration with an upper portion decreasing in diameter from a top opening to a midsection, and a lower portion increasing in diameter from the midsection to a bottom opening. A semi-circumferential arcuate relief extends partially, across the widths of the upper rings. The arcuate relief may have a plurality of grooves, dimensioned to have different widths and circumferential lengths. Additionally, the metal body has an interior chamber with a plurality of scratchings on it, which provide the drum assembly with a clearer voice and sound. The drum assembly may include a mallet, a cover made from a soft material, and an elastic cord.
