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.
