Meninas Cantoras de Petrópolis is the name of a pioneer Brazilian musical group composed exclusively of girls, founded in 1976, in the city of Petrópolis, by maestro Marco Aurélio Xavier. After a rigid evaluation of capabilities for Music, which starts at the early age of seven and lasts three years long studying theory and vocal techniques, following the Escolania de Montserrat method (Coro de Meninos, which began in the 9th century at the Abadia N. S. de Montserrat, in Barcelona), the singer girl will be tested on the "ceremony of investiture" and will be chosen to integrate the choir and maybe some day will put on the "Sapatinho de Verniz" (Coat Shoe) symbol.
