What age is needed to do the gumboot dance?
The only real attributes that are truly needed for physical dance would be the ability to move your body and a desire to do so. The experience of dance is enhanced if the dancer has a flexible body that moves easily and gracefully. It is important not to overlook the fact that dance has a core emotional component as well. Using movement as a form of personal expression is truly the goal of dance.
While it's true that you don't need a degree to dance, there ARE doctorates in dance if you want to pursue one; a couple of schools in the US that offer the degree are Temple and Ohio State Universities. I've linked the names of the schools to their pages on the program so you can read about exactly what is involved.
