ElevenLabs Music Generation

Generate music from text prompts - supports instrumental tracks, songs with lyrics, and fine-grained control via composition plans.

Setup: See Installation Guide. For JavaScript, use @elevenlabs/* packages only.

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'));

Methods

Method	Description
`music.compose`	Generate audio from a prompt or composition plan
`music.composition_plan.create`	Generate a structured plan for fine-grained control
`music.compose_detailed`	Generate audio + composition plan + metadata

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
)
