The Samoan ''siva'' dance has unique gentle movements of the body in time to music and tells a story, although the Samoan male dances can be more 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.
