Rio Carnival Parade 2013, Rio De Janeiro, Brazil

There is a special order that every school has to follow with their parade entries. Each school begins with the "comissão de frente" (Comission of Front in English), which is the first wing. The "comissão de frente" is made up of ten to fifteen people only, and they are the ones who introduce the school and set the mood. These people have choreographic dances in fancy costumes that usually tell a short story. Following the "comissão de frente" is the first float of the samba school, called "abre-alas" ( Opening Wing in English ).
Some of the important roles include the porta-bandeira and mestre-sala. The porta-bandeira is a very important lady who is in charge of the samba school flag, including making sure to not allow the flag to roll. She is accompanied by the mestre-sala, who is supposed to draw everyone’s attention to "his queen", the porta-bandeira. Floatees, who are also important, are the people who populate the floats, also known as destaques. The floatees have the most luxurious and expensive costumes that can be extremely heavy. Along with all the floatees is one main floatee that is located at the top of each float. The main destaque dances and sings for the entire time that the float is on the runway.
One other aspect that is mandatory is the presence of the ala das baianas. This is a wing of the samba school entry that includes at least 100 females only. These women along with many other people do not ride on the floats as many others do, instead they are passistas, the people who belong to the samba school that do the marching alongside and between the floats.
