The arm movement should be lively, energetic and natural. Keep the elbows generally close to the torso, but allow them to move naturally when needed. The upper arms may move slightly to support the rhythm. The forearms perform quick, compact vertical pumping motions. Increase the movement frequency by approximately 25%. Maintain a continuous flowing rhythm with no pauses or stiffness. Allow subtle natural shoulder and elbow movement to make the performance feel relaxed and human. The torso stays mostly stable but naturally follows the rhythm with very slight body motion. The motion should feel confident, loose and expressive rather than restricted or robotic. Preserve the original choreography while making the movement smoother, faster and more natural.
