Topshur (Топшур in the cyrillic alphabet of the Altayans) is a two-stringed plucked or strummed lute played by the Altayans. Related instruments include the Kazakh dombra, the Mongolian tobshuur (Mongolian: ᠲᠣᠪᠰᠢᠭᠤᠷ Tobshuur; Khalkha dialect: Товшуур Tovshuur; Chinese: 托布秀尔) and the Tuvan doshpuluur. The topshur's strings are tuned to an interval of a fourth. This instrument is usually used to accompany sung epics. The topshur is identical to the Khakas khomys (хомыс) and is played in a similar fashion.
