For some reason, I got postes as Phil. I was responding to phil.samways response.
It was not my intent to indicate that dancing along cures all ills. I don't spend an inordinate amount of time doing so. Mostly, I use it to isolate something that is difficult or confusing, where I can get my head around the proper movements.
I do have a perfect example of a pair that needs to be temporarily split up. They are beginners, and they are learning the beginning foxtrot 6 count basic. The gentleman is having a great deal of difficulty with the concept of stepping straight forward (there's that unfortunate circomstance of having someone right in front of him). It's likely that he could benefit greatly from a few times up and down the floor doing the basic without a partner, so he could get the feel for "his part". Then put him back with his partner and see if it helped.
