Construction: Made from bone, wood, or stone, it has intricate carvings on one side which make it both an unique musical instrument and an ornamental item of beauty. It is also attached to a cord or rope on one end.

How it is played: Sound is created when it is spun vigorously in the air in circles.

What it sounds like: The buzzing and fluttering sound created mimics the sound of insects and birds' wings.

Usage: In addition to being used as a musical instrument, the pūrerehua was used to call the rains and lure lizards out of hiding (mistakenly thinking that there were many insects nearby).

Also known as: bull roarer, rangorango
