Ginga is the most fundamental move in capoeira, the move that puts you in constant motion and must always be done when measuring up your opponent, or just simply keeping yourself in rhythm to the music. One very important thing to not, would be to not have your back foot crossing over the path of your front foot, which can tend to be a common mistake for a beginner. Such a mistake will cause one to be unbalanced, which does not bode well in capoeira.
