I was thinking yesterday about the track of the feet when walking to a cruzada, and would welcome others' views. I'm in a sports hall, using a white line (part of a badminton court) that runs the length of the room - a very convenient 'line of dance'. We're walking along it, in parallel, and I want to lead a straightforward cruzada. My understanding is that I introduce rotation of the embrace to the R, so that I am walking one or more steps with my L side leading. Through dissociation, my chest remains opposite the follower's, and while we continue to walk straight down the LOD, our feet are no longer sharing two tracks, but have made four. I lead the cross, by straightening the embrace, so that the separate tracks merge again. This is my question: when we separated tracks, how should the new ones have related to that white line? Should we each have moved slightly either side of it, so that it is between us, or should one of us (her, probably) have stayed on it, while I shifted to the left? When the tracks merged, did we come together, again, on that line, or on a parallel line slightly to its left? Or, alternatively, should I have stayed on it throughout, and moved the follower to the R, before bringing her back to where we both started? I don't intend anyone to think that I would want to dance in this way: but I am trying to develop my understanding of the relative movements of the couple in this common action, and fully accept that 'for real' a good deal of flexibility and fluidity is appropriate. I am thinking more in terms of a complete beginner's 'first attempt', and the underlying principle.
