Principles of Traditional Animation

The following principles were developed and named:

1. Squash and Stretch - defining the rigidity and mass of an object by distorting its shape during an action
2. Timing and Motion - spacing actions to define the weight and size of objects and the personality of characters
3. Anticipation - the preparation for an action
4. Staging - presenting an idea so that it is unmistakably clear
5. Follow Through and Overlapping Action - the termination of an action and establishing its relationship to the next action
6. Straight Ahead Action and Pose-to-Pose Action - The two contrasting approaches to the creation of movement
7. Slow In and Out - the spacing of the in-between frames to achieve subtlety of timing and movement
8. Arcs - the visual path of action for natural movement
9. Exaggeration - Accentuating the essence of an idea via the design and the action
10. Secondary Action - the action of an object resulting from another action
11. Appeal - creating a design or an action that the audience enjoys watching
