Algoza (alghoza) is a pair of fipple flutes. It is found throughout northwest India and Pakistan.
There are various approaches to the construction. Occasionally the two flutes are physically joined together, sometimes they are merely tied with a length of string, while sometimes they are completely separate.
The number of holes varies as well. Occasionally one flute has 6-7 holes and plays all of the melody while the other flute is drilled in such a way that it can only play a drone. However another common approach has each flute with an identical arrangement of holes, such that both flutes have the capacity to play a melody. In this latter case, one generally is limited to playing only a portion of the octave.
