What is a Tribo de Índios in Brazil Carnival?
Definition:
Originated in Paraíba State, tribos de índios, or tribos indígenas, are Carnival groups known for the intense rhythm of their music, colorful attire, and elements from traditional indigenous rituals such as pajelanças, incorporated into the Catimbó-Jurema religion followed by some of the participants.
Popular in Pernambuco Carnival and in other states as well - São Luís, in Maranhão, has several groups in its festivities - tribos de índios are similar to, but not quite the same as caboclinhos.
They have their own types of music and choreography, themes, costumes and instruments - harmonicas, for example.
Some of the themes in the parades can be war, ancestral leaders and death and resurrection. Elaborate headdresses, tomahawks, spears and shields are some of the accessories used. Groups are often named after Brazilian indigenous or even Native American nations.
Several groups meet for Carnival events such as the annual Festival of Caboclinho and Tribos de Índios in Recife, which in 2013 will start at 6 p.m. on Thursday, Feb.7 in front of Banco do Brasil on Avenida Rio Branco and parade towards Praça do Arsenal.
