Argentine tango has been seducing dancers for more than a century. Learning to dance tango socially focuses on the connection between partners and the expression of the music. Tango is often called an improvisational walking dance. This is to say that, while the dance may appear to be made up of complex memorized sequences, in fact each step is improvised in the moment from very simple elements. These are just some of the unique qualities that, along with tango's rich culture, create what many regard as the king of dances.
