Popular music since the late eighteenth century began to show signs of forming a characteristically Brazilian sound, with samba considered the most typical and on the UNESCO cultural heritage list. Maracatu and Afoxê are two Afro-Brazilian music traditions that have been popularized by their appearance in the annual Brazilian Carnivals. The sport of capoeira is usually played with its own music referred to as capoeira music, which is usually considered to be a call-and-response type of folk music. Forró is a type of folk music prominent during the Festa Junina in northeastern Brazil. Jack A. Draper III, a professor of Portuguese at the University of Missouri, argues that Forró was used as a way to subdue feelings of nostalgia for a rural lifestyle.
