A pinkillu,[1] pinkuyllu[2] or pinqullu[3] (Quechua or Aymara, Hispanicized spellings pincollo, pincuyllo, pingullo, pinquillo, also pinkillo, pinkiyo, pinkullo, pinkuyo) is a flute found throughout the Andes, used primarily in Argentina northwest, Bolivia, Chile, Ecuador and Peru.
It is usually played with one hand, leaving the other one free to accompany oneself on a drum[4] like the tinya.
In Peru and Bolivia, sheep and llama nerves are used to tie the instrument together.
In the Andes the instrument is played during the early rainy season to celebrate cattle and farming.
In Bolivia it is believed that the pinkillu made from cane attracts rainfall.
