Initially they danced the more daring steps between themselves but soon enough there were men dancing with these women. The men realized the need to practice Tango beforehand, as the dance requires the man to lead. Thus, men who used to go to these establishments, practiced among themselves. It is not an easy thing and the woman steps are different from the man's. Many Tango schools appeared by the start of the new century to address this problem.
Brothels are very dangerous places.
In them, the high class and the well to do mixed with the poor, the marginalised and criminal characters. Unsafe business, indeed. Slowly by 1910, Tango had escaped the brothels and had vanquished the lower classes by becoming less sensuous and more adapted to family and party audiences. Carlos Gardel is the undisputed main personality of Tango. His tragic fate, clipped his career by causing him to die young in a plane accident by 1935 when he was at the peak of his popularity.
