Hula dancing is a complex art form, and there are many hand motions used to represent the words in a song or chant. Foot and hip movements often pull from a basic library of steps. There are other related dances (tamure, hura, 'aparima, 'ote'a, haka, kapa haka, poi, Fa'ataupati, Tau'olunga, and Lakalaka) that come from other Polynesian islands such as Tahiti, The Cook Islands, Samoa, and Tonga; however, the hula is unique to the Hawaiian Islands.
