As just a social dancer I'm sure I always start a ballroom dance ( and most if not all of the numerous sequence dances I can do after a fashion) by moving my left foot forward and placing the weight on it (I'm a male) . But when I view ballroom demonstration videos (on YouTube) the male often moves his right foot forward at the start of the demo. I find this rather confusing - why does it happen? (If it's because the couple are demonstrating some steps that take place in the middle, not the start, of the dance, would it not be less confusing for a newbie dancer if s/he saw the demo with the man starting any moves by moving his left foot? In my minds eye, when trying to learn new ballroom or sequence moves, this is what i do; and I'm sure many newbie dancers too would like this to happen.) Thanks for any info.
