Sitar, a stringed instrument of Indian origin.
Sitar-bridge. The profile can be approximated by a parabolic curve. The base of the parabola defines the -axis passing through the far string termination point and parallel to the reference line shown, which runs along the neck of the instrument. See text for detailed dimensions.
Bridge-string geometry and different phases of string motion (exaggerated for clarity). The right string termination lies on the -axis; the left termination lies on the parabolic bridge surface as shown.
