One of the many main purposes of the Rio carnival parade is for samba schools to compete with fellow rival... not (they are called co-sisters) samba-schools; this competition is the climax of the whole carnival festival in this city, related to the samba-schools environment. Each school chooses a theme to try and portray in their entry. The samba schools work to build the best floats,costumes, lyrics, aesthetics, to represent their themes ( in Carnival terminology called "enredo"), and to include the best music they can from their drumming band called the bateria. There are many parts to each school's entry including the six to eight floats and up to 4,000 ( four thousand ) revelers per Samba-school of the so called Special group.
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 ).
