Listen to the music first, and then break down the movements step by step. There are more videos online. Find some clear ones. It's best to get down at least after listening to the music, and then watch the action with video every second. If the video is not easy to learn, I'll tell you a better way, that is, put the monitoring screen in front of the mirror, and you stand in front of the mirror, so that the actions you learn will not be reversed. Do as she does. Don't worry about it.
