yes, mirrors are for shaping and especially in our NV where a lot of what we do is to be a mirror image, we can see if our arms are the same height and look in harmony with each other...
But for other parts of our dancing, if your head is to be to the left well you cant look in the mirrors if it is at the right angle so you dont need one, it is up to the teacher...but I do miss the mirror for our NV. OUr teacher has had to move premises and the new one does not have mirrors. But we find another way to do it.
Um...you can always change your dance alignment so that you just catch a glimpse of the mirror when your head is in the correction position.
