Tangos is a flamenco canté closely related in form and feeling to the Rumba. It is often performed as a finale to a Tientos. Its compas and llamada are the same as that of the Farruca and shares the Farruca's lively nature. However, Tangos is normally performed in the A Phrygian mode.
Tango declined again in the 1950s with economic depression and as the military dictatorships banned public gatherings, followed by the popularity of Rock and Roll.
A striking difference between Argentine tango and ballroom tango is that the follower remains upright on her axis, or may even lean toward the leader (and in a close embrace dances "chest-to-chest" with the leader).
In ballroom tango the feet move before the whole body weight is moved, quite in contrast to argentine tango, where the body center starts to move and is then supported by the movement of the feet.
Tango took many years to spread to these boarding houses because their inhabitants were in general, decent people that did not want their families to be exposed to that sinful music and dance.
Tango was born in the periphery of the city, bars, cafes, brothels; from there it moved inside the city to Dancing Houses.
Tango was still a pariah, the bastard son of pimps and women of ill reputation, dressed like a poor compadrito.
