This is the Coral Natal de Luz (the Christmas of Light Choir) singing a poppy version of Beethoven’s “Ode to Joy” in Portuguese. The kids are all in different windows of a building in downtown Fortaleza, and if you look closely, you can see Santa in the bottom center window.
I’ve been studying Brazilian music for years now, but I still have lots to learn. I didn’t need any sponsorship from my university, but I did need letters of recommendation from professors. And it really helps to have some affiliation with a university or institution abroad. Are you wanting to study in Brazil? You should apply!
