The dancer is a musician whose instrument doesn't produce sound but movement. He's the one translating music into movement, through the emotion the music leads him to. For the authentic Argentinian milonguero, music is above all. He doesn't perform steps just because he knows how to. He chooses them to express what he gets from the music in the best way he can.
Music is the dancer's best ally.
When the dancer interprets the music correctly he becomes an artist. When he doesn't, he becomes a gymnast. Steps alone lead to the gym. Steps in concordance with the music lead to art. Bodies are unified by the embrace, space is unified by the floor, physical support of the body and movement.
