Here's the themes (Enredos) of each of the 12 samba schools parading in the top group of Rio carnival 2011, on the Sunday and Monday nights of carnaval. The Carnavalesco is the overall designer of the parade. Each school parades with around 4000 costumed participants and 8 large floats. The parade is divided into sections with costumes and floats illustrating aspects of the theme. Each school has its own song (samba enredo) written specially to explore the school's theme.
