The pan flute, also called Antara (in Quechua), Siku (in Aymara) or Zampoña (in Spanish), is a traditional Andean panpipe. It is a wind instrument consisting of cane pipes of different lengths tied in a row or in a bundle, held together by wax or cord; and generally closed at the bottom.

It is typically made of bamboo shoots, but has also been made of Condor feathers, bone, and many other materials.

The pan flute is played by blowing horizontally across the open end against the sharp inner edge of the pipes.

The most widespread variety of siku (siku ch'alla) contains 13 pipes (6 in ira and 7 in arka), but less common varieties may have more and less pipes. In this case, this Chromatic panflute has 44 pipes (22-22). There is no standardization in the construction of chromatic panpipes, and this is because most of them respond to the own particular musician needs.

The total number of rows in chromatic panflutes can be different from one type to another. The choice of more or less rows depends on the comfort and requirements of the instrument. 

The pan flute has long been popular as a folk instrument, and is considered the first mouth organ.
