ARGENTINE TANGO

Is a social dance and a musical genre that originated in Argentina and moved to Uruguay and to the rest of the world later on. In the US,
Ballroom tango steps were standardized by dance studios. The steps have been relatively fixed in style for decades.
However, Argentine tango has been an evolving dance and musical form, with continual changes occurring every day on the social dance floor in Argentina and in major tango centers elsewhere in the world.
Argentine Tango is still based heavily on improvisation. While there are patterns or sequences of steps that are used by instructors to teach the dance, even in a sequence every movement is led not only in direction but also speed and quality (a step can be smooth, pulsing, sharp, ... etc.).
