Hi, thank You.
By the way, I am also thinking about how to go to learn to dance tango.

Well, the most important thing for start is to find a school with good teachers that teach you the essence (good posture, balance, hug, musicality, leading, following) in great details before they give you attractive choreography. : )

Thank you for your advice. I'll use it of course.

Your most welcome. Cheers!
