Mambo/Salsa is the latin equivalent of Swing. Perez Prado is thought to have introduced it at La Tropicana nightclub in Havana in 1943. Mambo Mania hit when Prado recorded the song, “Mambo Jambo”. The dance appeared in the United States in New York’s Park Plaza Ballroom, a favorite hangout of dance enthusiasts from Harlem. The Mambo gained in popularity and in the 1950’s was taught in dance studios, resorts, and nightclubs in New York and Miami. In more recent times Mambo has also evolved into Salsa. Salsa is a street version of Mambo. Musically the main difference is that Mambo music holds on the one beat and Salsa music hits on one beat. The steps are pretty much the same. Mambo tends to be sharper in the footwork more time is spent in closed hold and the man breaks on 2. Salsa tends to be sexier, characteristically it has little kick like embellishments, more time is spent in a two handed or apart position and the man breaks on 1. Whether you call it Mambo or Salsa, the small steps are taken ball of foot first with the knees flexible to allow for the hip action known as cuban motion. Mambo is the forefather of Cha Cha. It also shares many patterns in common with the other Latin dances Rumba and Bolero. Mambo/Salsa is fun and flirty and socially is a great dance to learn if you like Latino music.
