 The term "tango nuevo" has been used in dance every time an Argentinian tango teacher came out saying he was teaching a new dancing style.For example, the term was used to refer to the tango of the old "Petroleo" around 1940, as well as around 1990-2000 when some Argentinian teachers promoted out-of-axis dynamics in their seminars around the world.Neotango uses standard tango biomechanics and the tango's flow on the dance floor.
