Ballroom dancing has characteristics of natural movement of human walking with a fixed constant musical tempo. The natural walking movement appears especially in the rise and fall in the swing dances of modern standard dances. The rise and fall in these dances is analyzed in the mechanical point of view. The rising and lowering processes in the swing action are discussed in detail in terms of mechanical energy. The case of natural turn in waltz is taken as an example and compared with other cases. A sinusoidal function of simple vibration is employed featuring the natural movement of rising and lowering process of the body. The height of center of gravity of dancer and its vertical acceleration are quantitatively exhibited in graphs for each basic movement of the figures of waltz, representing the standard modern ballroom dancing. It is shown that highest position in the movement depends on each figure in each dance and that it is limited by the lowering process in the figure.
