This past weekend I earned my first, second and third Capoeira cordas (the colored belts, as in any other martial art.)

Capoeira is a Brazilian martial art that developed in the slave camps as a way to train to fight for freedom, while disguising it as dancing and singing. Learning capoeira requires learning to play the instruments, sing the songs, hold the "axe" (energy) and obviously play in the center of the circle.  In capoeira, it's called playing; not sparring or fighting.
