Erke

The erke (alternatively erque, coroneta, or quepa) is a large labrosone (lip reed) instrument native to the Gran Chaco of Bolivia, northern Chile, and the Argentine Northwest.

[1] The erke is composed of two or more lengths of cane joined at the ends to form a single tube.

The internal nodes of the canes are removed and the exterior is often wrapped with gut or wool.

Although in the latter half of the 20th century Andean folkloric musical groups have used the erke for secular music, among the indigenous and criollo peoples of the Andes the erke is used solely for ritual purposes.

[2] Among the Mapuche people, there exists a similar instrument called the trutruca.
