They were Canela People.
This dance made a kind of hypnosis sensation.
While they were reapeatting their words and shaking the rattles, the women was swinging subtle their bodys, and the arms were waggling.
Was fascinating for me to see their arms going to front and behind the body, all synchronized.
The Canela People live in Maranhão State from Brazil.
They were divided in two sub-groups: Ramkokamekrá and Apanyekrá.
Population about 1.337 Ramkokamekrá (in 2001) and 458 Apanyekrá (in 2000).
