Swing
In general, swing, or body swing, is any free movement around a fixed point. We can distinguish between "pendular swing" when the fixed point is at the top of the movement and "metronomic swing" when the fixed point is at the bottom. A common example of swing (pendular) is movement of the free foot forward and up to a point about three inches above the floor, keeping the leg straight; no weight change. (Compare to kick.) Also a dance rhythm—see Jive or West Coast Swing in the navigation bar at the upper left of each page.
