But the parade (游行) preparations are not easy.    2     Everything must be done by the time the parade is held in February, summertime in Brazil.

The song creation is one of the most important parts of the celebration. The samba music is the life of the parade. A group of musicians and writers chooses a historical theme and transforms it into an upbeat piece of music.     3     It must make it impossible for those who are listening to stand still.

In the same way, the costumes add beauty and color to the parade.    4     Satin, feathers, and many other flashy materials are used. The costumes are chosen according to the theme. Most parade groups allow tourists to participate, but they also must wear the costumes, which can cost from $300 to more than $1,400.
