Added to the list of posts to read before you d.. Tango Demons by Carrie Whipple via Alex.Tango.Fuego.
In it there is one key line:
The teamwork required to dance tango well is so much more important than any one person’s individual technique.
Too much focus is placed on technique as though perfect technique is the goal of tango. Teamwork is the goal of tango. Technique is what you use to remove the physical obstacles to that teamwork.
I like that.
