The difference of this style of dancing is the lack of space. The milonga in Buenos Aires downtown area is small and with a lot of people dancing at the same time. In this situation, the way of dancing is in a very close embrace. We dance with regular size steps, like walking. Many times we even take smaller steps and few very times longer steps. We change direction and front very often as well as different rhythmic patterns.
From my experience, I believe that everyone who wants to dance tango would highly benefit learning with this way of dancing. What do you think?
