Ipu /ˈiːpuː/ is a percussion instrument made from gourds that is often used to provide a beat for hula dancing.
There are two types of ipu, the ipu heke ([ˈipu ˈhɛke]), which is a double gourd made by taking two gourds of different sizes, cutting them and joining them at their necks with the smaller one on top, and the ipu heke ʻole ([ˈipu ˈhɛke ˈʔole]), which is made from a single gourd cut across the top. Both are made from gourds that have been dried, hollowed and usually polished smooth with sand or sandpaper.
