3. Submit — generate and download your music clip.

Example Prompt

Dark ambient sci-fi underscore, deep pulsing bass drones, ethereal synth pads, subtle percussion, tense and mysterious, space horror atmosphere, no melody, slow tempo.

Pricing

Just $0.08 per clip.

Best Use Cases

• Film & Video Scoring — Generate high-quality music beds and underscore for professional video productions.

Pro Tips

• Be specific about BPM, key instruments, and energy level for the most accurate results.
• Put exclusions in the prompt itself, for example “no vocals” or “no drums”.
• Generation is not deterministic; run the same prompt again to get a new variation.
• Try pairing atmospheric images with a minimal prompt to let the image drive the mood.
• Use the Prompt Enhancer to expand a simple style reference into a detailed music description.

Notes

• Only prompt is required; image is optional.
• Please ensure your content complies with Google’s usage policies.
