Trống cơm

Trống cơm (lit. "rice drum") is a kind of traditional barrel-shaped Vietnamese drum, bearing similarities to the Chinese yaogu, and the Khmer skor sang na. It is an integral instrument in the hát bội orchestra and is also featured prominently in the Hát chèo repertoire. The trống cơm is a long, cylindrical drum with percussion surfaces on both ends.
