Whenever I go dancing at a club, I get two very different styles of how people maintain their hands during a dance. Some people have their hands very loose and let them flow with the music. Others have very rigid arms and they do not move at all. I understand the reason for this is so the follow can easily detect the lead beginning a move. However it feels so natural to just relax your arms and let your hands flow with the music. Is there a right or wrong way for this? Which way should be encouraged?
