Listen to the Drums: click link below
Drums are percussive instruments built by stretching a membrane across an opening in a vessel. The sound originates from the vibration caused when you strike the membrane, called the head, with another object. Drumheads can be made from the skin of a goat, cow, antelope, or sheep, or even a synthetic material. Across the world, cultures carve drums out of wood, sculpt them out of clay, hammer them out of metal, or mold them out of plastic. The kinds of drums that exist vary as infinitely as the people who use them for communication, ritual, or entertainment.
