Hi all! In the forward checks of the cha cha box-step, should the non-supporting leg be straightened or bent? Or are both acceptable? While I have seen and have been taught that the non-supporting leg be straightened, I have seen examples where the dancers' non-supporting leg is bent. What brought my attention was a particular video with basic cha cha cha steps. (I can't post links at the moment, but the video can be found on YouTube by searching for “Sergey Melia Basic Cha Cha”) Right at the beginning, you can see Mr Sergey Surkov's non-supporting leg is bent for the checked forward walk (is it what it's called?). This is done throughout the dances shown in the video for that particular step. Also, secondly, I've also noticed that for the same step, his supporting leg doesn't seem to be fully perpendicular to the floor. That is, it is at an angle like “/ ”, and not the usual “|”, where the dancer's weight appears to be fully on it. Are these alternative styles and/or interpretations for the forward checks? Or are they different steps altogether (with different names)? Mr Surkov does not do the same in the rumba video. Would it be because it is idiosyncratic to the cha cha cha? For speed? This seems to be more common with male dancers, at least from the videos I've seen. (on a similar note, I've seen what appear to be like New Yorks to me, but also done with a bent supporting leg. Or are they Cuban breaks? I'm not sure...) Thank you for your time, everyone! Have a great day!
