Introduction: A Newcomer level move. A key component of how you move in Waltz.
Frame: Standard. Count: Waltz. 1-2-3.
Leaders and Followers: Applies to both equally.

Instructions (Leader and Follower Perspective)
After having looked at the Waltz Basic-Technique page (you did look at it, right? If not, I highly recommend doing so), you're now ready to learn how to actually (somewhat) move in waltz by applying the idea of drive.
But before we do that, there's one last exercise to be done. This exercise focuses on how your upper body moves when doing a natural turn (as opposed to a reverse turn). The difference occurs because in waltz, your partner is slightly to the right of you. In natural turn, you turn to your right. In reverse turn, to your left. When turning to your right, your partner is already out of your way. But when turning to the left, your partner is in your way. We fix this by treating natural turn and reverse turn differently.

Exercise 1a: Natural Turn, No Upper Body
This is similar to the Waltz box step exercise as you do trace out a box. However, we need four 1-2-3 counts of waltz to complete this box.
Assume a basis of right leg moving forward (You have to. Natural turn is turning to your right, meaning right foot first. Left foot first is reverse turn). Similar to box, if the right leg moves first, the box is on the left.
1. Right leg drives forward.
2. Transitioning from split position, left leg comes forward. As your feet come together, both knees should be bent. When your feet are together, pivot on your right foot 90 degrees to face right. Then, your left leg slides out to your left, very little weight on it, ultimately with your right leg pushing off to finish the weight transfer.
3. This is where your right foot comes next to your left and you go onto toes.

1. Left leg drives backward.
2. From split position, right leg comes back. Similar to step 2 above, you turn 90 degrees to your right, this time using your left leg as the pivot.
3. Same as before, but this time with your left foot coming to meet your right.
Repeat the above two 1-2-3 counts to end up where you started.

Exercise 1b: Natural Turn, Upper Body incorporated
The Natural Turn above has you turning 90 degrees at a single spot: the pivot point on count 2. This exercise changes that, by spreading the 90 degree turn throughout count 1, so at the end of count 1, your upper body is facing the correct direction (90 degrees right of original direction).
1. As your right foot drives forward, you are lowering your body. In this lowering, think of corkscrewing down, turning to your right. Don't twist excessively, do what your body lets you do. At the end of 1, you have lowered the most. Consequently, this is also when your upper body should be facing 90 degrees to your right, though your feet are still proceeding as in the previous exercise.
2. Same as before, left leg comes forward. Finish the weight transfer.
3. Go onto toes.
Complete three more of these to finish. When going backwards, the split position should match the split position when going forward: weight is split, front foot on heel, back foot on toe, and most importantly, torso turned to the right.
Note: If we subdivide Waltz as 1-and-2-and-3-and, there are two important things to note. First, the "3" is the apex. The "and" following the "3" is the lowering of the body to proceed into 1.

Tips and Tricks
Efficiency: Drive. The deeper the drive, the further you can go, the more efficient your energy use, the better you look. Caveat: Don't drive so low as to cause either you or your partner pain.
You can fly, you can fly, you can fly: Correct Driving = swooshing across the floor. At not point in natural turn should you do something that causes you to ruin the smooth rise and fall of waltz.
Open the Door: When doing a natural turn forward, the follower is doing a natural turn backwards. Meaning, the upper body turning is extremely important. Why? Because unless that happens, the person doing the forward turn is going to get blocked by the partner's body. Think of the upper body turning as opening a door.

Advanced Concepts
Sway: Think of a bike or a motorbike. When the riders make turns, how do they do it? They certainly don't just turn the handles, like you might with a car. Instead, they lean their body in the direction they're turning. Analogous to this is the concept of sway in ballroom. When driving, you're not going to end up in a straight-up down position. In fact, if you're executing drive correctly, you shouldn't be able to finish with your spine perfectly straight when on toes because you've accumulated enough momentum such that you'll fall over. Instead, your spine curves. And the direction it curves is the same as the first foot you stepped with. So if you begin with natural turn with your right foot, you'll end with your spine slightly curved to the right. And when you take a 2nd natural turn, your left foot is first, so your spine will be curved to the left. Note: From a Leader's perspective. For followers, you'll begin natural turn with your left foot, so your spine will curve to the left.
Important to note is that if you're doing drive correctly, sway is what will happen so that you end up in a more efficient position. You should NOT try to make your spine curve unnaturally unless you executed drive correctly such that your step inclines you to do so.
