This is one of the ancient percussion instruments of Iran used in sport arenas during a traditional form of sporting activity in order to harmonize movements. It resembles a very large tombak, and its bowl is made of clay. It sounds sharper than the tombak, and a considerable amount of physical strength is needed to play it. The instrument is placed on the ground due to its heavy weight and is played by both hands.As its name suggests, this instrument is constructed from a large and a small drum set side by side. It is considered a wartime instrument by the Kurds, suspended from the neck of horses in the front of the cavalry and played in order to spur the warriors. Similar to the tâs, the do-tablé consists of metallic bowls covered with skin fastened by belts on the sides, and is also played by two short leather straps. The larger drum has a more base tone whereas the smaller drum has a sharper tone. Do-tablé resembles the Indian Tabla, except in that the Tabla has a more diffused sound and is played with the fingers.
