## The Murch Hierarchy

1. DIALOGUE
   The spine of the piece. Everything else supports this.
   "If you can't hear what they're saying, nothing else matters."

2. KEY STORY SOUNDS
   The sounds essential to narrative comprehension.
   Examples: Phone ringing that starts the scene, door slam that ends it

3. MUSIC
   Emotional foundation and pacing.
   Supports but never competes with dialogue.

4. EFFECTS
   Environmental sounds, action sounds, transitions.
   Creates context and reality.

5. FOLEY
   Subtle human sounds: footsteps, clothing rustle, object handling.
   Adds life and presence.

---

Rule: Each layer yields to those above it.
Music ducks when dialogue begins.
Effects clear space for key story sounds.

## The Law of Two and a Half

"Beyond three similar sounds playing simultaneously,
something chemical happens—the brain stops tracking
individual elements and perceives a new, unified sensation."

### How to Use It

**For Realism**: Layer 3+ similar sounds
- City ambience: traffic + distant horns + pedestrians + AC hum
- Result: Feels like a real city, not "sound effects"

**For Clarity**: Stay under 3 elements
- Dialogue scene: voice + subtle music + room tone
- Result: Clear, focused, intelligible

**For Impact**: Cross the threshold intentionally
- Climax moment: Layer multiple hits, impacts, swells
- Result: Overwhelming sensation (use sparingly)

### Practical Application

| Scene Type | Recommended Layers | Example |
|------------|-------------------|---------|
| Dialogue-heavy | 2-3 | Voice, music bed, light ambience |
| Emotional peak | 4-6 | Voice, score, effects, foley, room |
| Transition | 1-2 | Music, light effects |
| Action | 4+ | Multiple effects, hits, music |

## Worldizing Technique

**What It Is**:
Play recorded audio through speakers in a real space,
re-record it with microphones to capture the room's acoustic character.

**Why It Works**:
Stock music and studio recordings sound "too perfect."
Worldizing adds the imperfections that make audio feel real and present.

### DIY Worldizing for Marketers

**Option 1: Physical Worldizing**
1. Play your music/VO through a speaker in the space you're depicting
2. Record with a microphone capturing room reflections
3. Blend with original for desired effect
4. Example: Music playing from a "radio" in scene

**Option 2: Digital Worldizing**
1. Use convolution reverb with impulse responses of real spaces
2. Apply room simulation plugins
3. Add subtle distortion/EQ to simulate speaker playback
4. Roll off highs and lows to simulate distance

**Option 3: Practical Recording**
1. Record actual room tone in your location
2. Layer beneath all other audio
3. This single element dramatically increases perceived realism

### When to Use

✓ Music that's "source" (playing in the world, not underscore)
✓ Flashback sequences
✓ Documentary-style content
✓ "Behind the scenes" feeling
✓ Any time you want audio to feel "there" vs. "added"

## Sound-Emotion Mapping

### Build Your Arc

1. **Identify Key Emotional Beats**
   - What should viewer feel at 0:00? 0:30? 1:00? End?
   - Map the emotional journey

2. **Assign Sound Strategies to Each Beat**

   | Emotion | Sound Strategy |
   |---------|---------------|
   | Tension | Sustained tones, rising pitch, reduced elements |
   | Release | Musical resolution, fuller spectrum, exhale sounds |
   | Intimacy | Close mic perspective, reduced ambience, whisper range |
   | Power | Low end emphasis, layered impacts, space/reverb |
   | Joy | Bright frequencies, uptempo, organic sounds |
   | Melancholy | Minor keys, sparse arrangement, room tone |
   | Urgency | Fast pacing, compressed dynamics, clipping/distortion |

3. **Create Transitions**
   - Sound bridges between emotional states
   - Pre-lap audio (sound starts before visual cut)
   - Post-lap audio (sound continues after visual cut)

### Example: 60-Second Brand Film Arc

0:00-0:15: PROBLEM (Tension)
- Minimal music, discordant undertones
- Harsh office sounds, fluorescent hum
- Tight, dry vocal treatment

0:15-0:35: DISCOVERY (Curiosity → Hope)
- Music enters subtly, builds
- Sound design softens
- More space in mix

0:35-0:55: SOLUTION (Confidence)
- Full musical support
- Warm, rich sound design
- Open, confident vocal treatment

0:55-1:00: RESOLUTION (Satisfaction)
- Music resolves
- Key brand sound/sonic logo
- Comfortable silence
