Argentine Tango is a very individualistic dance. For this reason it doesn't translate well to learning by "step patterns".
The content of this video is excellent because it teaches the beginning "grammer" that a dancer needs to know in order to dance Argentine Tango. With the few basic concepts that are outlined on this tape, a dancer can be dancing "basic" Argentine Tango - as a follower or a leader - anywhere.
I learn dances best when I learn the "structure" behind the moves, not just the moves themselves. This tape is great for that.
You will NOT like this tape if you want step patterns layed out for you to memorize.
