Summarize this article:

You can make the circular motion using a ¼ to ¾ turn, depending on your preference. To move in a circle, you and your partner will complete the first two steps of the waltz. Then, the lead will place their left foot at a slight turn on the third step and the follow will place their right foot in the same direction. This will then allow you to turn slightly as you perform the waltz. The circular motion will always be to the lead’s left. You and your partner should move in a smooth, fluid turning motion to the left as you complete the steps. The lead should start facing diagonally to a wall in the room, with the follow facing the opposite direction. The lead will then step forward on their right foot and the follow will step backward on their left foot. The lead will take a quarter turn to the left, placing the left foot parallel to their right foot. The follow will turn with the lead, placing their right foot parallel to their left. The lead will bring their right foot beside their left, and the follow will bring their left foot beside their right to end the step. Follow a 3-count pattern when performing the turn.  Make sure you open your body to the side when you do the quarter turn to the left or to the right, depending on whether you are the lead or the follow. Keep your arms and elbows up, landing softly on the ball of your foot when you perform the turn. Dance with your partner using the first 3 steps of the box step, or waltz. Then, on step 4, the lead will release the follow by dropping their right arm. The lead will then raise their left hand and spin the follow in a clockwise turn towards the left. The lead should continue to do the box step for counts 4,5, and 6 as the follow spins on these counts. The follow should move forward in the turn on counts 4, 5, and 6. The lead and the follow will then meet at the starting position at count 6.  Make sure the lead takes shorter steps on counts 4,5,6 so they do not get in the way of the follow. The follow should move forward in a smooth, fluid turn, using a pattern of heel, toe, toe, putting weight on their heel for count 4 and then on their toes for count 5 and 6.

Summary:
Move in a circle with your partner. Add a basic turn to your waltz. Do a waltz underarm turn.
