Ng’ngốc is the name of the Mnông ethnic minority, referring to the Jew’s harp. Ng’ngốc is a thin bamboo piece with two crossing lines cut in the middle to create two sides of an isosceles triangle. The bottom side is located at the instrument body. This triangle is the reed of this instrument. T he performer puts this instrument between his two lips without touching his teeth. His left hand keeps this instrument steady, and the right one shakes the instrument very slightly to create sounds inside his mouth. Changing the shape of his mouth will create some overtones, different from the sound created by the reed. The sound from this instrument is soft and slightly cracked.

The Gogiya Bin Baja is a harp of the Pardhan community of Central India. It is played only by this community, and hence is presented here because of its rarity. It is played by Ram Prasad who is also singing.
