However, I really don't believe that it can happen in the dance as what you see and what is happening is not the same thing. OK..if Tango was a sport, and someone decided to train their two daughters to be world champs...and he/she had some personal brilliance about 'learning' and 'teaching' ..sure, I will agree that it can be done. But this doesn't happen in Tango. ..
I think it is feasible that someone who cannot dance particularly well themselves due to physical limitations or whatever, might still be able to visualise brilliantly and foster their vision in someone who is physically well-adapted for the task.
One difference that occurs to me is that in the arena of sport all that is necessary is to beat the opposition according to a clear set of criteria. Tango is much more complicated than that - there is no clear definition of "brilliance".
