The morin khuur is an instrument that comes from Mongolia, but is also played by the Tuvans. It is similar to the igil, but contains some subtle differences. The instrument and it's playing technique changed in the 20th century under the influence of the European cello. Therefore the morin khuur's soundbox is made entirely of wood instead of utilizing skin. It has a trapezoidal shape and typically has European style holes cut into the top on either side of the bridge. The two strings are tuned either a fourth or a fifth apart. The low string is on the right side from the frontal aspect.
