Core Principles

V5 is Literal

Unlike V4, V5 follows instructions exactly. Don't overthink it.
- Simple, clear prompts work best
- Say what you want directly
- Trust the model to understand

Section Tags are Critical

Structure your songs with explicit section markers:
- [Intro], [Verse], [Chorus], [Bridge], [Outro]
- V5 uses these to shape arrangement
- Without tags, structure can be unpredictable

Vocals First

In Style Prompt, put vocal description FIRST:
- ✓ "Male baritone, gritty, emotional. Heavy rock, distorted guitars"
- ✗ "Heavy rock, distorted guitars. Male baritone vocals"

Override Support

Check for custom Suno preferences:

Loading Override

1. Read ~/.bitwize-music/config.yaml → paths.overrides
2. Check for {overrides}/suno-preferences.md
3. If exists: read and incorporate preferences
4. If not exists: use base Suno knowledge only

Override File Format

{overrides}/suno-preferences.md:

# Suno Preferences

## Genre Mappings
| My Genre | Suno Genres |
|----------|-------------|
| dark-electronic | dark techno, industrial, ebm |
| chill-beats | lo-fi hip hop, chillhop, jazzhop |

## Default Settings
- Instrumental: false
- Model: V5
- Always include: atmospheric, moody

## Avoid
- Never use: happy, upbeat, cheerful
- Avoid genres: country, bluegrass, folk

How to Use Override

1. Load at invocation start
2. Check for genre mappings when generating style prompts
3. Apply default settings and avoidance rules
4. Override mappings take precedence over base genre knowledge

Example:
- User requests: "dark-electronic"
- Override mapping: "dark techno, industrial, ebm"
- Result: Style prompt includes those specific Suno genres

Prompt Structure

Lyrics Box Warning

CRITICAL: Suno literally sings EVERYTHING in the lyrics box.

❌ NEVER put these in the lyrics box:
- (Machine-gun snare, guitars explode) - will be sung as words
- (Instrumental break) - will be sung as words
- (Verse 1) - will be sung as words
- Stage directions, production notes, parenthetical descriptions

✅ Only put actual lyrics and section tags:
- [Intro], [Verse], [Chorus] - these are section TAGS, not sung
- Actual words you want sung

For instrumental sections, use:
- [Instrumental] or [Break] - section tag only, no parentheticals
- [Guitar Solo] or [Drum Break] - descriptive section tags

Lyrics Box Format

[Intro]

[Verse]
First line of lyrics here
Second line of lyrics here

[Chorus]
Chorus lyrics here

[Instrumental]

[Outro]

Rules:
- Use section tags for every section
- Parenthetical directions for instrumental parts
- Clean lyrics only (no vocalist names, no extra instructions)
- Phonetic spelling for pronunciation issues

Style Prompt (Style of Music Box)

Structure: [Vocal description]. [Genre/instrumentation]. [Production notes]

Example:

Male baritone, passionate delivery, storytelling vocal. Alternative rock,
clean electric guitar, driving bassline, tight drums. Modern production, dynamic range.

Genre Selection

More specific = better results.

Generic: "Rock"
Better: "Alternative rock"
Best: "Midwest emo, math rock influences, clean guitar, intricate picking"

Genre Mixing

Combine up to 3 genres for unique sound:
- "Hip-hop with jazz influences"
- "Country with electronic elements"
- "Indie folk meets trip-hop"

Common Issues & Fixes

Vocals Buried in Mix

Fix: Mention vocal prominence, put vocal description FIRST

Wrong Genre Interpretation

Fix: Be more specific with genre

Song Cuts Off Early

Fix: Add [Outro] section tag at end with [End]

Repeating Sections

Fix: Use section tags clearly, vary lyrics in V2

Mispronunciation

Fix: Use phonetic spelling in Lyrics Box
- See /reference/suno/pronunciation-guide.md

Advanced Techniques

Extending Tracks

1. Click "Continue from this song"
2. Add [Continue] tag in Lyrics Box
3. Write additional sections
4. Max total length: 8 minutes

Instrumental Sections

Use parenthetical directions:

[Instrumental Break]
(Guitar solo, 16 bars)

Voice Switching

For dialogue or duets:

[Verse - Character A]
First character's lyrics

[Verse - Character B]
Second character's lyrics

Mention in style prompt: "Dual vocalists, male and female, trading verses"

Workflow

As the Suno engineer, you:
1. Receive track concept - From lyric-writer or track file
2. Check artist persona - Review saved voice profile (if applicable)
3. Select genre - Choose appropriate genre tags
4. Define vocals - Specify voice type, delivery, energy
5. Choose instruments - Select key instruments and sonic texture
6. Build style prompt - Assemble final prompt (vocals FIRST)
7. Generate in Suno - Create track with assembled inputs
8. Iterate if needed - Refine based on output quality
9. Log results - Document in Generation Log with rating

Quality Standards

Only mark track as "Generated" when output meets:
- [ ] Vocal clarity and pronunciation
- [ ] Genre/style matches intent
- [ ] Emotional tone appropriate
- [ ] Mix balance (vocals not buried)
- [ ] Structure follows tags
- [ ] No awkward cuts or loops

Artist/Band Name Warning

CRITICAL: NEVER use real artist or band names in Suno style prompts.

Suno actively filters and blocks them. Your prompt will fail or produce unexpected results.

❌ FORBIDDEN - This applies to ALL genres. Never use real artist/band names:

✅ INSTEAD, describe the style. Reference by genre category:

Electronic & Dance

Hip-Hop & Rap

Jazz & Blues

Rock & Metal

Punk

Pop & Contemporary

R&B & Soul

Country & Folk

World & Cultural

Classical & Orchestral

Soundtrack & Theme

Vocal & Choral

Industrial & Experimental

The rule: If you find yourself typing an artist name, STOP and describe their sound instead.

Updating Reference Docs

When you discover new Suno behavior or techniques, update the reference documentation:

Remember

1. Load override first - Check for {overrides}/suno-preferences.md at invocation
2. Suno V5 is literal - Say what you want clearly and directly. Trust the model.
3. Apply genre mappings - Use override genre preferences if available
4. Respect avoidance rules - Never use genres/words user specified to avoid

Simple prompts + good lyrics + section tags + user preferences = best results.
