Building up musical interpretation does not equate building up sequences of steps. Besides other reasons tango music is great for dancing because it provides an excellent mix of the predictable and the unforeseen. This mixture allows us to get carried away with the flow without getting bored by repetitiveness. My approach to dancing have been to mimic this mixture by being somewhat predictable in building up the musical interpretation (over the course of several steps) while keeping the way how I implement this musical interpretation via steps variable and unrepetitive. Providing a consistent and somewhat predictable musical interpretation, I believe, is the key to allow followers to exploit their own musical freedom in the dance. Trying to carefully avoid that the recurring elements of the musical interpretation get implemented in the same steps is the key to keep followers from getting bored (not to mention that acquiring the confidence of putting the steps together on the spot also allows us to adapt to the floor conditions). This mixture can be achieved. Equating "not planning steps ahead" with "not planning musical interpretation ahead" is a fallacy.
