Revolved poses like Twisted Angle, Twisted Side Angle, Twisted Triangle, Seated Twists, Revolved Wide Legged Forward Folds, Twisted Plank, Twisted Downdog, Twisted Pigeon all share a common feature: the spine revolves - one vertebrae a little over the other. This causes the second feature: the ribs and pelvis end up facing different directions, up to ninety degrees offset. The neck may also turn, though that’s best left to last. More on that later. 

Remember: “the spine” is not one thing. It's a series of large things at the base that get smaller the further you go up. There are other things (bones) attached to these things that restrict motion in places. So the rotation should happen a little at a time and not in one, big swing. (See Tips, below).
