suno_generate_custom_music
Generate AI music with custom lyrics, style, and title. Control every element from verse structure to vocal gender.
Instructions
Generate AI music with full control over lyrics, title, and style (Custom Mode).
This gives you complete creative control over the song. You provide the lyrics
with section markers, and Suno generates the melody and arrangement.
Use this when:
- You have specific lyrics you want to use
- You want precise control over the music style
- You need a specific song title
- You want to specify vocal gender (v4.5+ models)
- You want the API to auto-generate lyrics from a prompt (use lyric_prompt)
For quick generation without writing lyrics, use suno_generate_music instead.
Returns:
Task ID and generated audio information including URLs, title, lyrics, and duration.
