## Positive Prompts Are Only Half the Mix

Creators stack genre words for ten minutes and still hear muddy vocals, surprise trap hats on an acoustic ballad, or a mid-song key change nobody asked for. The missing half is **exclusion**: telling Suno what not to do via Exclude Styles / negative constraints (wording varies by UI), plus careful Style phrasing.

This playbook lists twelve high-frequency failure modes with a short diagnosis and a copyable exclude set. Use one or two excludes per generation—flooding the field with twenty bans can confuse the model as badly as over-prompting.

## Who This Is For

Anyone shipping tracks for video, ads, or demos who needs fewer regenerations. Also useful for teams that share Style templates: attach an exclude line so juniors do not rediscover the same artifacts.

## How to Use Exclude Without Fighting Style

1. Write a clear positive Style first (genre, tempo, vocal type, mix feel).
2. Add **2–5** excludes aimed at the actual defect.
3. Keep excludes concrete (`autotune`, `crowd noise`) rather than vague (`bad music`).
4. If the result gets thin or lifeless, remove half the excludes and regenerate once.

Pair excludes with structure tags in Lyrics. Form problems are rarely fixed by bans alone.

## The 12 Recipes

### 1) Muddy / buried vocals

**Symptom:** Words smear; consonants disappear under pads.  
**Exclude (copy):** `mumbled vocals, washed-out vocals, excessive reverb on vocals, choir stacking`

**Style companion:**

```text
intimate lead vocal, dry-to-light room, clear diction, midrange-forward mix, 96 BPM indie pop
```

### 2) Harsh autotune / robotic pitch

**Symptom:** Hard pitch correction on every syllable.  
**Exclude (copy):** `heavy autotune, robotic pitch correction, metallic vocal artifacts`

### 3) Electronic drums on an acoustic brief

**Symptom:** 808s and trap hats invade folk / singer-songwriter.  
**Exclude (copy):** `808s, trap hi-hats, electronic drums, sidechain pumping`

### 4) Random key / mode flips

**Symptom:** Chorus lands in a new key without a bridge intention.  
**Exclude (copy):** `sudden key change, unpredictable modulation, chaotic harmony`

Also keep Lyrics simple and repeat chorus lines; unstable lyric content can encourage wandering.

### 5) Fake live applause / stadium noise

**Symptom:** Crowds appear on a studio ballad.  
**Exclude (copy):** `crowd noise, applause, stadium ambience, live concert effects`

### 6) Endless spoken intro / radio DJ talk

**Symptom:** Host-style speech before the song starts.  
**Exclude (copy):** `spoken word intro, radio host voice, talk break, podcast dialogue`

### 7) Overlong silence / dead air

**Symptom:** Gaps that kill short-video timing.  
**Exclude (copy):** `long silence, empty bars, sparse dead air, fade-out too early`

### 8) Genre bleed (metal growls on pop)

**Symptom:** Extreme vocal styles appear uninvited.  
**Exclude (copy):** `death growls, screamed vocals, extreme metal vocals`

### 9) Cartoon / novelty FX

**Symptom:** Risers, vinyl stubs, meme SFX when you wanted clean.  
**Exclude (copy):** `cartoon sound effects, meme sfx, exaggerated vinyl crackle, glitch spam`

### 10) Overcompressed / crushed loudness

**Symptom:** No dynamics; ear fatigue in twenty seconds.  
**Exclude (copy):** `overcompressed mix, brickwall loudness, distorted clipping`

### 11) Duplicate-sounding AI choir wall

**Symptom:** Soft stack that hides the lead.  
**Exclude (copy):** `thick stacked choir, oversized harmony wall, karaoke backing choir`

### 12) Unwanted language switch

**Symptom:** Chorus flips language mid-song.  
**Exclude (copy):** `language switching, multilingual ad-libs, random foreign phrases`  
(Also state the language positively in Style: `English lyrics only` or your target language.)

```

## Before / After Style Blocks

**Before (too open):**

```text
emotional song, nice vocals, modern production
```

**After (positive + excludes):**

```text
Style: indie pop ballad, 88 BPM, warm piano, soft male vocal, clear lyrics, natural dynamics
Exclude: heavy autotune, crowd noise, 808s, long silence, sudden key change
```

**Before (genre mush):**

```text
hype track for youtube
```

**After:**

```text
Style: upbeat electronic pop, 124 BPM, bright female vocal, punchy kick, short hook-friendly sections
Exclude: spoken word intro, meme sfx, overcompressed mix, death growls
```

## Lyrics Hygiene That Helps Excludes Work

- Prefer short chorus lines you can sing twice.
- Mark intentional quiet with `[Instrumental]` instead of blank space.
- Put delivery notes sparingly: `[Whispered]` then return to normal—do not stack five delivery tags per line.

## When Excludes Are the Wrong Tool

If the melody is wrong, regenerate or Sample a better hook—do not ban “bad melody.” If you need a different genre entirely, change Style rather than excluding the whole world. If two songs should collide, use Mashup instead of fighting a single Style field.

## Build a Shared Exclude Library

Create three team presets and stop reinventing bans:

| Preset | Use | Core excludes |
|--------|-----|----------------|
| `clean-vocal` | Ballads, brand songs | `heavy autotune, mumbled vocals, choir stacking` |
| `acoustic-safe` | Folk, singer-songwriter | `808s, trap hi-hats, electronic drums` |
| `short-form` | Reels / ads | `long silence, spoken word intro, crowd noise` |

Store them next to Style skeletons. Juniors should only add excludes when a defect appears twice—not on the first draft.

## Regeneration Order That Saves Credits

1. Fix Lyrics structure tags if form is broken.
2. Tighten positive Style (tempo + vocal + mix).
3. Add two targeted excludes.
4. Only then change mode (Sample / Mashup) or start over.

Skipping to step 4 is how credit balances disappear.

## Wrap-Up

Exclusion is a precision tool: name the artifact, ban it briefly, keep the positive Style clean. Save your twelve recipes as a team checklist, then generate inside MidassAI Studio Suno so the same exclude lines travel with every brief.
