I have a former professional dancer friend who refused to do WCS. She said she never has any idea what the guys were doing. Part of that is that most people (both men and women) aren't listening to the music. They are just doing their moves. Oh, once in a while they'll hit a break, etc, but in general... In order to improvise (to the music) you have to be able to communicate what you want to happen to your partner. Noodle arms? Maybe they are being taught to "lead with their center". That is a fine concept, but, just as in Argentine Tango, something gets lost in translation, and you end up with a weak lead, and woman who don't want to be "pulled" or "pushed". Meanwhile, last night, one of partners stopped me while I was on my way to dance the "Cha Cha Slide - Part II", a line dance with called moves. (You can find it on the web.) She asked if I wanted to do WCS to it. I thought WTF???? for about 2 seconds, and said yes. (She loves to just make stuff up as much as I do.) Now, I find it darn near impossible to "turn off the music" and just dance what's in my head. And this song changes a lot, calls for you to stomp two times, cha cha, go down low, do "Charlie Brown". Well, we winged the whole thing. There was some WCS in there, I guess, with me trying to "hop three times",etc while making it look and feel like West Coast. We may have looked completely goofy, but what the heck. And there is one key to improvising. If it doesn't work, so what? Wasn't it fun trying?
