# Secondary Action Mastery

## The Enrichment Principle

Secondary action adds life to a scene without distracting from the main action. A character walking (primary) while whistling and swinging their arms (secondary). A button pressing (primary) with a subtle ripple effect (secondary). It's the difference between functional animation and rich, immersive motion.

## Core Theory

**Subordination principle**: Secondary action must never compete with primary action. If viewers watch the secondary instead of primary, you've failed. The supporting role must remain supporting.

**Reinforcement function**: Good secondary action reinforces the primary action's meaning. It doesn't just add motion—it adds dimension to the story being told.

## The Distinction: Secondary Action vs. Overlapping Action
