The Samba is a lively Brazilian dance which was first introduced in 1917 and was finally adopted as a ballroom dance by Brazilian society in 1930. It is sometimes referred to as a Samba, Carioca, a Baion or a Batucado. The difference is mainly in the tempo, since the steps in all four dances are very similar. The style is to bounce steadily and smoothly in 2/4 meter. They say that the Samba was introduced in the United States in 1939 by the late Carmen Miranda.
