Traditional dance
As for technique/ style, it really varies. Traditionally, its appropriate to keep your feet flat and both your feet and your knees together while dancing. Feet are slightly in a “V” shape, but not an exaggerated “V.” The shoulders should remain still, and so should the chest (of course if youre big-breasted, there will be some movement of the susu, but not a lot). Some girls start trying to fa’arapu so fast that they start moving their whole body to gain momentum and speed, and that hurts you in a competition. Upper body should remain steady; arms should be outstretched, but not stiff, and fingers and toes should be together and relaxed. If a dancer has their back facing the audience, you shouldnt see one ankle continually popping up, or one leg pumping more than the other, or the toes up in the air. The faarapu should be even, not one side stronger than another. Many girls emphasize their backs, because the faarapu is typically the biggest and strongest when looking at it from behind, but there should be a roll to the stomach in the front as well. I know in competitions, some judges mark girls off if they have no visible faarapu when facing the front.
