Selecting Parent and Children

When animating, large movements that are made at the root (parent) of a chain cause secondary movements throughout the rest (children) of the chain. For example, when you rotate the arm of a character from the shoulder, the forearm and hand will follow. However, in order to make the movement appear natural and graceful, the forearm and hand should not move at the same speed or angle. As a result, animators often need to move up and down a chain, intermittently selecting parent and children, in order to make both large and fine movements.
