Date of issue: September 25, 2001. Narkobyz is a name of the biggest shaman Kobyz. By right it is regarded as one of the most ancient stringed musical instruments in the world. The Kobyz (Kazakh: қобыз) or kyl-kobyz is an ancient Kazakh string instrument (chordophone) of the type known as a bowed lyre. It has two strings made of horsehair. The resonating cavity is usually covered with goat leather. Traditionally kobyzes were sacred instruments, owned by shamans and bakses (traditional spiritual medics).

According to legends, the kobyz and its music could banish evil spirits, sicknesses and death. In the 1930s, when the first folk instrument orchestras were established in the Soviet republic of Kazakhstan, a new kind of kobyz came into existence. It now had four metallic strings and thus became closer to a violin. Such a modernized kobyz can be used to play both Kazakh music and the most complicated works of violin literature. One of the few western musicians to use the kobyz is Trefor Goronwy. The kyl kyyak is a stringed musical instrument used in Kyrgyz music. The instrument is carved from a single piece of wood (typically apricot) and typically measures 60-70cm. It has 2 strings, one to provide melody and the other resonance. The kyl kyyak is played vertically with a bow and can be played on horseback. The strings and bow are normally made from horse hair and many instruments feature a carved horse's head. This all reflects the importance of the horse in Kyrgyz rural culture.
