There are some great schools in Brazil. Carla Korbes studied at Ballet Vera Bublitz, which invited a Principal Dancer from New York City Ballet to dance Apollo with its young students. That's how Peter Boal discovered Carla Korbes and managed to convince her parents to send her of to NYC to School of American Ballet as a teenager. She danced with NYCB for a while, but Peter Martin's idiocy was Pacific Northwest Ballet's gain. (She'll dance Juliette in Jean-Christophe Maillot's "Romeo et Juliette on Friday/Saturday evening 15-16 February, when PNB visits NYC.) The New York Times critic, Alastair Macaulay, looooooovvvvvessss her.
The director of Centro de Dança Rio has partially funded training and trips to NYC for YAGP for her most talented students. Irlan Silva ("Only When I Dance") won the YAGP junior division in 2005 and got an apprenticeship through Prix de Lausanne in 2008. He went to ABT II from there and is now at Boston Ballet. He danced on the little stage at the Guggenheim during a 95th birthday tribute to Frederic Franklin, who staged the Raymond excerpts he and other ABT II members danced. (Lovely, elegant dancer.)
There's a long tradition of the schools in Brazil sending their kids to the contests for exposure -- most of the YAGP judges are from dance companies, and they're always scouting for kids for their school -- and, hopefully, scholarships and opportunities. Now that DVD's and videos are the road to getting auditions, it's a bit easier in less traveled parts of the ballet world, but while some of the best dancers I've ever seen, male and female, have come from South America, I think South America is sadly under-represented. (There was a little recognition boom when ABT had a group of excellent male dancers that people grouped together as "South American," which lumped in the Brazilians, the Cubans, and the Spanish.) Still, the competition circuit has become traditional, and a lot of the teachers/coaches go for the same variations, at least in the classical choreography.
