Batucada developed in Brazil as a percussion driven form of samba, rooted in Afro Brazilian musical traditions and performed by large drumming ensembles called baterias. It became closely associated with Rio de Janeiro samba schools and Carnival parades, where dozens of players keep a relentless, interlocking rhythm for dancers. Recordings, films, football culture and touring percussion groups carried the sound far beyond Brazil during the twentieth century. Online, short batucada clips now travel as a ready made shorthand for carnival, celebration and Brazilian identity, easily dropped into edits without needing a full song.
