The folia de reis Christmas tradition of southeastern Brazil involves a group of musicians and clowns traveling from house to house in a symbolic re-enactment of the journey of the Magi. The performers sing to bless the families they visit, and the families contribute money and food; the money is used to mount a festival on 6 January for the contributors.
Familial symbolism operates on various levels: At each stop, the group begins with an adoration of the Holy Family; then they sing directly to the members of the family they are visiting, with verses ordered to reflect traditional familial hierarchy; and the culminating festival unites all of the faithful in a symbolic extended family. The performing group itself is organized on a familial model.
This according to “The family in song: Vocal organization in the Brazilian folia de reis” by Suzel Ana Reily, an essay included in Ethnomusicologica II (Siena: Accademia Musicale Chigiana, 1993) pp. 203–213. Below, folia de reis in Miracema.
