The manganhars consider themselves descendants of the Rajputs and are renowned as folk musicians of the Thar desert. Their songs are passed on from generation to  generation as a form of oral history of the desert. The traditional Jajman (patrons) of the manganhar are the locally dominant Rajput community, while the Langha have a similar relationship with the Sindhi-Sipahi, a community of Muslim Rajputs. At times of birth, marriage or any family festivity for their Rajput patrons, the manganhar musicians sing songs of the desert and many specially composed songs to praise the patron and his family . Present circumstances. In 1978, Jodhpur-based musician Komal Kothari provided the manganhars with institutional support, allowing them to sing outside the state for the first time. Currently, several  manganhar groups tour internationally. Instruments. Kamaicha The 17-string khamaycha is a bowed instrument. Made of mango wood, its rounded resonator is covered with goat skin.
