What is erkencho material?

Erkencho is a traditional wind instrument of the Mapuche people of Chile and Argentina. The instrument is made from a hollowed-out tree trunk and has two or three reed or bamboo pipes attached to it. It is played by blowing air into the pipes, which then produce a harmonic sound. The sound of the instrument is similar to that of a clarinet, although the erkencho has a more rustic and earthy tone. The erkencho is often used in Mapuche ceremonial music and has become an important symbol of Mapuche culture. Nowadays, the instrument is made with a mixture of traditional and modern materials, such as plastic and metal.
