Start with your feet together and arms down with your hands in a soft, cupped form. You should have your posture being straight and tall with your chin up.
Take a step out with your right foot, while your right arm slowly lifts up to between chest and eye level. The left arm will move up and out to the left side.
Lift your left leg up in the back while you are stepping out on the right foot. The left leg should be kept straight and strong. Keep your toe pointed while the leg lifts up.
Keep your hips straight and forward or parallel to the wall or mirror you are facing. Your body stands strong and erect. You are attempting to lift your back left leg up in proper technique to meet your back that is standing strong. Do not break your posture while making this movement.
Hold your arabesque pose. Your right leg and foot are supporting your body.
Reverse all the above steps if you want to start on your left foot. It doesn't matter which foot you step out on.
Perform this classic low arabesque in flat ballet slippers flat on the floor. As you become a more advanced ballet dancer, you will be able to go up on your toes or even "en pointe." Practice your technique and you'll be there soon.
