## Prompt Engineering Tips

### Be Specific About Style
- Include genre, mood, tempo, and instruments
- Reference decades or eras: "90s Brazilian romantic pagode", "1960s sci-fi TV theme"
- Describe energy: "builds from soft to explosive", "relaxed and intimate"

### For Vocals
- Specify language: "vocals in Portuguese", "singing in Japanese"
- Describe vocal style: "soulful male vocals", "ethereal female choir"
- Include lyrical themes: "about love and saudade", "celebrating friendship"

### Avoid Copyright Issues
- Don't mention artist/band names directly
- Describe the style instead: "classic 90s romantic samba style" not "like Raça Negra"
- If rejected, the API returns a suggested alternative prompt

### Example Prompts

**MPB (Brazilian Popular Music)**
```
A soulful MPB track featuring gentle acoustic guitar, warm nylon strings, 
and dreamy Rhodes piano. Bossa nova-influenced rhythm with soft brushed 
drums. Vocals in Portuguese express themes of saudade and the beauty of life.
```

**Epic Orchestral**
```
Epic military march with powerful brass fanfares, thundering timpani drums, 
and a soaring choir. Triumphant and heroic, with deep bass tubas, bold 
trumpets, snare rolls, and an anthemic melody building to a glorious crescendo.
```

**Lullaby**
```
Gentle orchestral lullaby with sweeping strings, soft brass, and ethereal 
wordless soprano vocals. Peaceful yet majestic, evoking wonder and hope. 
Perfect for falling asleep while dreaming of adventures.
```

**Comedy Rock**
```
Brazilian comedy rock with absurd, hilarious Portuguese lyrics full of 
wordplay. Mix energetic rock guitars with unexpected rhythms - forró 
breakdowns, pagode moments. Theatrical, exaggerated vocals singing about 
ridiculous situations.
```
