I think you would nearly always dance on the 1 beat. I regually come across dancing on the 1,2 or 1,3 or 1,2,3. I have not come across dancing on the 2 or 3 or 2,3 before but I suppose that is possible.
but I have not come across dancing on the half beat before and other variations implied in the above post, I find these difficult to conceptulise. Indeed the arguement always seems to be whether it is correct to call dancing on the 1,2 or 1,3 double time or not.
