Kurdish tanbur or tanbour a fretted string instrument, is an initial and main form of the tanbūr instrument family, used by the Kurds. It is highly associated with the Yarsan religion in Kurdish areas and in the Lorestān provinces of Iran. It is one of the few musical instruments used in Ehli Heq rituals, and practitioners venerate the tembûr as a sacred object. Another popular percussion instrument used together with the tembur is the Kurdish daf, but that's not sacred in Yarsan spirituality and Jam praying ceremony.
