Q: How is the siva different from the slap dance?, Context: The Samoan word for dance is siva with unique gentle movements of the body in time to music and which tells a story, although the Samoan male dances can be more physical and snappy. The sasa is also a traditional dance where rows of dancers perform rapid synchronised movements in time to the rhythm of wooden drums (pate) or rolled mats. Another dance performed by males is called the fa'ataupati or the slap dance, creating rhythmic sounds by slapping different parts of the body. This is believed to have been derived from slapping insects on the body.
