Undoubtedly, tango holds a privileged position in the representation of the Argentine abroad. While, basically, it is known as a dance and a music which can be sung, tango also contains a particular language (lunfardo), certain usages and customs, and even a characteristic philosophy identifying tango people.
At an international level, in order to distinguish it from so many other forms that appear in dance halls, it is known as Argentine tango.
It was this which gave rise to all the other forms.

The birth of tango took place towards mid-19th century, with the formation of dwelling conglomerates around the young city of Buenos Aires. Those who lived there, peasants from inland, European immigrants and some disadvantaged porteños (born in Buenos Aires) made up a new social class. Perhaps as a way of identifying themselves as a group and of feeling they belonged in their new home, they began to create cultural expressions derived from this mixture. This was the start of tango, characterized by its extremely closed codes, which were only accessible to the working classes.

Due to this impossibility of understanding by other audiences, the diffusion of tango was difficult and was basically approached through dance, which was earlier than tango itself in its most characteristic musical format (let alone sung tango, which arrived much later). It is clear that tango culture, understood as some particular usages and customs, is earlier than tango as an artistic expression. Salon dances involving a man and a woman embracing were the precedent for tango, which was refined until it became what has long been known as tango. Somebody said: -Tango is something else than a soft wave turned into music, it is the deepest dance in the world -, and he who spoke these words was not Argentine. The truth is that it must be acknowledged that it represents the last step in the universal dance evolution as regards dances of mixed couples.

What started with dance was eventually coming of age in the expert hands of great men, who, inspired in the popular melting pot, captured the richest part of the Buenos Aires culture in their compositions. Themes always refer to the ordinary man and his problems, the city and memories. Thus, tango becomes a portrayal of Buenos Aires and its people. For this reason, undoubtedly, since the best of the Buenos Aires culture is carried in each song, tango gained ground abroad.
