After submission, a task_id will be returned. If you provided a callback_url, when the task status becomes finished or failed, a POST request will be sent to the callback_url.
Regardless of whether callback_url is provided, you can retrieve the result through the unified Query Task Status endpoint.

elevenlabs-music generates music audio from a text or a structured composition plan. Results are returned as task files, matching the standard image, video, 3D, and audio task response structure.

Models

elevenlabs-music - ElevenLabs Music generation with text and composition-plan controls

Input modes

Provide exactly one creative control path:

Use text for a single text brief.
Use composition_plan for section-level arrangement control.
Do not send both text and composition_plan in the same request.

Optional parameters

All supported input fields. text or composition_plan is required, depending on the input mode:

text: Text describing the music to generate. Required when composition_plan is not provided. Length: 1-4100 characters.
composition_plan: Structured composition plan. Required when text is not provided.
- positive_global_styles: String array of global styles to include.
- negative_global_styles: String array of global styles to avoid.
- sections: Non-empty array of music sections.
  - section_name: Section name, 1-100 characters.
  - positive_local_styles: String array of section-specific styles to include.
  - negative_local_styles: String array of section-specific styles to avoid.
  - duration: Section duration in seconds, 3-120. This public PoYo field uses seconds.
  - lines: Lyrics lines. Each line must be 200 characters or fewer.
duration: Optional song length in seconds. Must be 3-600 when provided. Only valid with text.
is_instrumental: When true, requests instrumental-only output. Only valid with text.
respect_sections_durations: Controls how strictly section durations are followed. Only valid with composition_plan.
output_format: Output format. Defaults to mp3_44100_128.
