Tango as a three-body problem

   Here is an idea about tango that has been in my mind for a while. I will start by quoting the all powerful wikipedia.

   "The three-body problem is the problem of taking an initial set of data that specifies the positions, masses and velocities of three bodies for some particular point in time and then determining the motions of the three bodies, in accordance with the laws of classical mechanics."

   "In 1887, mathematicians Ernst Bruns and Henri Poincaré showed that there is no general analytical solution for the three-body problem given by algebraic expressions and integrals. The motion of three bodies is generally non-repeating, except in special cases."

    To me, Argentine tango is like a three-body problem: leader, follower and the music. We can predict and practice precisely what happens with either one object - personal techniques, music structure, etc. We can, though more complicated, systematically work on either two of the objects, such as connection between the couple, or understanding the music. However, when three objects, lead, follow and music come together, logic and mechanics become insufficient. All the technical elements still are and have to be there, but just not enough. Something more emerges. That is where art starts. That is where tango happens.
