No mystery about but it just a given, n=2 for Tango, the world-famous ballroom dance which started from the streets of Buenos Aires. It is believed to have started in the tambo, or the gathering of poor people from the slums near the silvery Rio Plata where they made music and dance and thus, in the tambo developed the Tango. It would help much the Filipino reader to consider the native broom which was taken from the gathering of tambo reeds and binding them together.
