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. Some of them employ extra open-ended reeds attached to the front of the instrument to change the sound quality.

There are multiple different sizes of pan flute, typically tuned an octave apart. The smallest of the family is called Ika or Chulli. The next larger size, the most common, is called Malta. An octave lower than the Malta is the Sanka or Zanka. The largest of the family is the Toyo or jach'a. The widest pipe of the Toyo is typically around 4 feet (120 centimeters).

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