Just like every shot in golf from tee to green, getting your set up correct is essential. It's important to have an appropriate stance width to make sure you can maintain balance and have the ability to finish on your left side at the end of the swing. Your feet should be just slightly wider than your hip joints. Ball position should be opposite your left heel with your hands positioned in the middle of your body. If you have a relatively new driver that is 460cc (read big head) you'll want to position the ball height so that it's at least ¾ above the top of the clubhead. This is key...pull your right shoulder back and down slightly to create a spine angle that tips slightly away from the target. This upper body position ensures that you will turn sufficiently over your right side in the backswing and helps create the proper path on the forward swing. If your arms swing where your shoulders point at address (too far left) you'll create a path on the forward swing that is "too steep" relative to the ideal arc around your body. This slight tilt away from the target with your upper body not only creates the proper path, but also helps create the proper launch angle on the forward swing.
A good way to learn the proper tilt is to hold the grip end of the club against the middle of your chest with the clubhead hanging down between your legs and lean to the right with your upper body so the clubshaft touches the inside of your left leg. Then you'll know that you have the right amount of tilt with your upper body for a successful tee shot.
