The big drum consists of a drum body, a drum head, It is composed of drum circle, drum card and drum hammer.

The big drum is a double-sided membrane sounding instrument with no fixed pitch, but the intensity of the pronunciation can be controlled. Use drums and hammers to strike the sounds and express different musical emotions with changes in force. Its sound is deep, loud, majestic and powerful, and is suitable for imitating thunder and cannon sounds.

The big drum is the largest drum in the orchestra, with a diameter of nearly 1 meter. Constructed of leather-covered wooden frame. It is usually held upright when played, and although there may be one or two tympanic sides, only one is actually used. The drum is struck by a single drumstick, called a drumstick, with two heads that can be used, and the heads are covered with wool or felt.

Usually when percussion, it is between the center of the eardrum and the rim of the drum. The center of the drum is only used for short and fast percussion (staccato) and special effects. Although the modern bass drum has been widely used in symphony bands, it initially entered Europe along with other percussion instruments of Turkish military bands in the late 18th century. Before the mid-19th century, it was generally only used to imitate the acoustic effects of military bands.
