This is the official dance of Brazil. Samba is one of the popular types of Latin dances in ballroom competitions. Before samba became a ballroom dance style, there were original partner samba dances, the most common of which is the 'Samba de Gafieira'.This samba is thought by many to be a cross between a waltz and a tango. Because it is a more spontaneous dance than the tango, the posture of the dancers is more relaxed, but this samba does have some common elements with tango. Originally, the dance was a simple partner dance, but as the samba has evolved over time, more and more tricks, turns, and other acrobatic feats have been added into this type of samba.
