Quick Start

### Python

from elevenlabs import ElevenLabs

client = ElevenLabs()

audio = client.music.compose(
    prompt="A chill lo-fi hip hop beat with jazzy piano chords",
    music_length_ms=30000
)

with open("output.mp3", "wb") as f:
    for chunk in audio:
        f.write(chunk)

### JavaScript

import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";
import { createWriteStream } from "fs";

const client = new ElevenLabsClient();
const audio = await client.music.compose({
  prompt: "A chill lo-fi hip hop beat with jazzy piano chords",
  musicLengthMs: 30000,
});
audio.pipe(createWriteStream("output.mp3"));

### cURL

curl -X POST "https://api.elevenlabs.io/v1/music" \
  -H "xi-api-key: $ELEVENLABS_API_KEY" -H "Content-Type: application/json" \

Composition Plans

For granular control, generate a composition plan first, modify it, then compose:

plan = client.music.composition_plan.create(
    prompt="An epic orchestral piece building to a climax",
    music_length_ms=60000
)

# Inspect/modify styles and sections
print(plan.positiveGlobalStyles)  # e.g. ["orchestral", "epic", "cinematic"]

audio = client.music.compose(
    composition_plan=plan,
    music_length_ms=60000
)
