What should the knees do during the propelled pivot turn?

During the propelled pivot turn, the knees should relax to allow for smooth movement and proper technique. When dancers relax their knees, it facilitates the necessary fluidity in the motion, making the pivot turn more graceful and controlled. A relaxed knee position also helps in absorbing any impact, which contributes to better balance and stability throughout the turn.

Maintaining rigidity in the knees can hinder flexibility and the overall aesthetic of the movement. If the knees were to bend backwards or stay extended, it would negatively impact the dancer's ability to pivot effectively, potentially leading to a loss of balance or incorrect body alignment. Therefore, relaxed knees are essential for executing the propelled pivot turn correctly and fluidly, allowing for both style and function in the dance.
