The rhythm and timing of animation is like a good musical score - it builds to crescendos and drops into quiet - it surges and it slows - it lifts and it falls. An audience needs that change. It must have periods of excitement and periods of rest. Our action must have variety and vitality in timing lest it becomes monotonous and irritating. Action, like emotion, needs change to get and keep the viewer’s interest. It has to be alive. We might say it has to be moody, impulsive, sprinkled with surprises. It has to have zest, humor, drama and meaning. How? Through expressive drawings, movement patterns and our timing and acting skills!
