The kyl kyyak (Kyrgyz: кыл кыяк ) (sometimes spelt kyl kiak and sometimes without the 'kyl') 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. The Kyrgyz word кыл/qyl means "string of an instrument" or "horse's hair".
