(Sihu) is a Mongolian bowed string instrument. The sound box is made of
wood and mounted with a piece of snake skin. Four metal strings are arranged
in a way that the first and the third strings are in a group. They have
the same tuning (in G). The second and the fourth strings are another group.

bundles, one between the first and second strings, the other between the
third and fourth strings. The playing of khuuchir is similar to that of
