This action gives the illusion of weight and volume to a character as it moves, anticipation prepares the audience for a major action.

The character is about to perform.

Each major action is preceded with specific moves that anticipate for the audience what is about to happen staging?

It's the presentation of an idea so that it is clear straight ahead and pose to pose.

Post opposes charted with key drawings done at intervals throughout the scene.

Straight ahead.

Animation starts at the first drawing and works drawing to drawing to the end of the scene, follow through and overlapping when the main body of the character stops, all other parts continue to catch up to the main mass.

Nothing stops all at once, slow in and slow out as the action starts, we have more drawings near the starting pose, one or two in the middle and more drawings near the next post fewer drawings make the action faster and more drawings make the action slower, marks all actions.

With few exceptions follow an arc or slightly circular path, arcs give animation a more natural action and better flow.

Secondary action.

It's an additional action in the scene used as a supplement of the main one in order to reinforce it and add more dimension, timing more drawings between poses slow and smooth the action, fewer drawings make the action faster and CRISPR timing maintains the appearance of an object abiding by the laws of physics exaggeration remain true to reality, just presenting it in a wild or more extreme form, solid drawings.

It means taking into account forms in three dimensional space, giving them volume and weight appeal.

It's a quality of charm, able to please the viewer's eyes.

It's the charisma of the action.
