Partnering         When two dancers dance together, they open up many more options for movement. In general, the woman is for imagery and the man is the muscle, his job being to make the woman look good. This is done in many ways through assisted balances, assisted turns, and lifts.         The same general physics concepts apply to partnered moves, but their sources may differ. For example, a woman is able to balance in a much wider range of positions when she has a partner to assist her. As shown is the picture to the right, the woman is in a position that would be very difficult to balance in by herself. The man can move the woman's center of mass to keep it directly over her contact point with the floor so that she can achieve more difficult positions. http://www.berkeleyside.com/2012/10/12/swan-lake-review-needs-to-go-friday/ http://operachic.typepad.com/opera_chic/2007/03/       During lifts, the man must not only be able to keep his center of mass over his contact point with the ground, but he must be in control of the woman's center of mass as well. As mentioned in the section on balance, if both feet are on the ground, there is a large area that the center of mass can be situated over. For this reason, it is common for the man to have a wide stance during a lift because it makes it easier to balance. Another tricky aspect of lifts is finding the best point of contact between the man and the woman. Hand placement is very important in the lift that is illustrated to the left. If the man's hands are too far towards the woman's head, she will fall forward, but if they are too far towards her feet then she will fall back. It takes a lot of practice in each lift for the man to become familiar with each woman's center of mass. Laws, K. (2002).
