  • To create a sound, there needs to be movement. That’s because sound is a form of energy. This activity uses a model of a pūrerehua (or pūrorohū) – a Māori musical instrument – to investigate the link between movement and sound.

    Traditionally, pūrerehua are made from bone, wood or stone. They have an oval (elliptical) shape and a long cord. When the pūrerehua swings in the air, it makes a whirring sound. The pitch varies depending on how fast the pūrerehua is swung. Swinging the pūrerehua rapidly produces a higher-pitched sound, and swinging it slowly produces a lower-pitched sound.

    Students are encouraged to use a variety of materials to create pūrerehua and investigate how the materials affect the sound the pūrerehua makes and to investigate speed and pitch.

    By the end of this activity, students should be able to:

    • experiment with movement and sound
    • begin to discuss the relationship between movement and sound
    • design and create a model of a pūrerehua
    • use the pūrerehua to create sound
    • discuss differences in the sounds created by pūrerehua made of different materials
    • retell some of the cultural aspects of pūrerehua.
