Common Mistakes in Third Position Arms | Vaganova Method

I find myself giving these corrections all the time to students. Let's have students/dancers understand why the third position must be done a certain way.
Just like all other positions, one leads to another position. If the previous position is out of place, then it will be difficult to make sure the next position will be executed properly.
