Anyways, he told me to strum by rotating my arm. Not up and down from the elbow. The way he described it was like opening a doorknob. To picture the movement, put your arm straight out in a fist as if you were holding a pole vertically. Then rotate your arm so the pole would be horizontal, then back to the original position. That "rotating" movement is what he wants me to do to strum the guitar. I don't see the benefit of not allowing your arm to go up and down, but only in this rotating thing.

If I understand what your instructor is trying to say, it would be the same as good circular alternate picking. It's really about economy of motion and using the larger muscle groups to your advantage. In my opinion anyway.

It sounds like the instructor wants you to move your arm somewhat in a 'sawing' motion or like the arm that moves the wheels on an old steam locomotive.

I always thought that doing so economized motion even though with larger groups. It gave more strength and less complexity to pick movements. Think about country or folk strumming, you do so with the whole of your arm. I think this apply to many motions on the guitar. The larger in size the muscle group, the more apt it is to handle repeated motions over a longer period of time and do so with assisting accuracy. In this case, many of the motions you will do in classical are lent to using this kind of motion for what little I know about it.

Just my experience, anyway.
