Begin in fourth position. In this position, the feet are parallel to each other, with the right one in front and the left in back. Both feet should be turned out, away from your body.
Bring your arms out in front of you as though you are holding a beach ball. Keep the round shape and extend your left arm out to the side at a 90-degree angle from your hips. You will turn in the direction of the rounded arm.
Shift your weight so that most of it is on your left leg.
Bring your left toe up to your right knee, keeping your right knee bent. Your left knee should face in front of you. As you make this movement, rise onto the ball of your right foot and bring your left arm in as though you are holding a beach ball. Practice this several times while maintaining balance before attempting to turn.
Practice turning once you are able to quickly bring your left toes to your right knee while rising to the ball of your foot. Use the shift in your weight, not your arms, to make the turn. "Winding up" with your arms will not give you momentum but will simply throw you off balance.
Keep your hips square and back straight as you turn.
Practice the single pirouette until you have mastered it. Once you have, you can move on to a double pirouette.
