When you dance, you play an instrument: your own body. In tango, you play toguether with another “musician” the music that is already playing. But there is a subtle diference between just following the music and the sensation that you are creating this music toguether. Everyone who dance tango knows how to step in the beat, but this knowlegde is unconcious. The “musician” is able to analize all the diverses lines of a song (beat, rythm, melody, armony, structure) and choose, during the dance, different instruments to play with, looking for diverses emphases and dynamics, listening also the music that comes up from his/her own partner.
