The Gopichand, a rhythmic folk instrument of Bengal, is mainly used by the
Baul, the wandering minstrels. Popularly known as Gopiyantra or Khamak, this instrument is made of bamboo. The two ends of a split bamboo are attached to a resonator which may be a metal container, gourd or a coconut. Taut skin is used to cover the open end of the resonator. A string passing across the hollow part of the resonator is attached to a tuning peg in the bamboo. The Gopichand is used with other musical instruments like Kartal and
Dotara.
