Origin.
Zumba was founded in 1998 by Pérez in Cali, Colombia. Pérez, an aerobics instructor, forgot his regular music to his aerobics class. He pulled out cassette tapes of Hiphop music instead and danced to them, which Pérez later taught as "Rumbacize." In 2001, Pérez partnered with Alberto Perlman and Alberto Aghion, and the trio released a series of fitness
, soca and quebradita. Once the instructor has included the four core rhythms in the playlist, he/she can choose out of the other six official rhythms or other internationally famous songs to finish off his/her 1-hour Zumba playlist. Other very popular rhythms that could be found in a Zumba class are: dancehall, dembow, bhangra, hip-hop, bachata, mambo.
