Patent abstract
A bass drum 10 has a hollow cylindrical shell 11, a drumhead 12 mounted on an opening end of the shell 11 to form a striking surface, and a striking surface attachment 13 provided on the reverse side of the drumhead 12. The striking surface attachment 13 is formed of an elastic sheet. At least a part of an outer area of the striking surface attachment 13 is fixed to the drumhead 12 and a central area of the striking surface attachment 13 is not fixed to the drumhead 12. As a result, the bass drum 10 can generate a struck sound having both deep bass sound and clear attack.
