Nuevo tango is either a form of music in which new elements are incorporated into traditional tango music, or an evolution of tango dance that began to develop in the 1980s.
Prior to the 1990s, Argentine Tango was taught with a didactic method; teaching tango by having students copy examples shown by the instructor. Emphasis was not given to how or why movement was done a certain way. Starting in the 1990s in Buenos Aires, the Tango Investigation Group (later transformed into the Cosmotango organization) founded by Gustavo Naveira and Fabian Salas applied the principles of dance kinesiology from modern dance to analyze the physics of movement in Argentine tango. Taking what they learned from this analysis they then began to explore all the possibilities of movement within the framework of Argentine Tango. From the work of these founders of the Tango Nuevo movement, there was shift in all styles of tango away from teaching what to dance toward teaching how to dance.
Though widely referred to as a tango style outside of Argentina, Tango Nuevo is not considered a style of dancing tango by the founders of the movement. It refers only to the method of analysis and teaching developed through the application of the principles of dance kinesiology to Argentine Tango. In 2009, Gustavo Naveira published an essay New Tango in which he states, "There is great confusion on the question of the way of dancing the tango: call it technique, form, or style. The term Tango Nuevo, is used to refer to a style of dancing, which is an error. In reality, Tango Nuevo is everything that has happened with the tango since the 1980s. It is not a question of a style... The words Tango Nuevo express what is happening with tango dancing in general; namely that it is evolving." Therefore, as Gustavo Naveira and the other founders of the Tango Nuevo movement have said, all styles of tango, which have now been influenced by the analysis of the dance, are all Tango Nuevo.
Despite the insistence by the founders of the Tango Nuevo movement that it is not a single style, it has become an accepted term by many that it is a separate and distinct style of tango. Considered by many as the most famous practitioners of tango nuevo are Gustavo Naveira, Norberto "El Pulpo" Esbrés, Fabián Salas, Esteban Moreno, Claudia Codega, Sebastián Arce, Mariana Montes, Mariano 'Chicho' Frumboli, and Pablo Verón. All of these dancers have highly individual styles that cannot be confused with each other, yet are all referred to by many as the tango nuevo style.
