The dance used by indigenous people in religious ceremonies and later became popular in hip hop culture is the Sway.
<h3>What is the Sway?</h3>
The sway is a dance step in which the individual moves alternately his/her head, arms and shoulders in coordination from sides to side. This dance step has a very ancient origin because it was used by some indigenous groups as part of their religious ceremonies.
Later it became popular because in the 90s some hip hop singers and dancers performed it in different presentations.
This is an example of the adaptability that some indigenous practices have to transcend for several generations without disappearing.
