Pahu

The pahu is a traditional musical instrument of the native Hawaiian people. Carved from a single log and covered on the playing end with a stretched sharkskin, the pahu is played with the palms and fingers of the hand. It is considered a sacred instrument and was generally kept in a temple (heiau), and used to accompany a repertoire of sacred songs called hula pahu.
