When to use ElevenLabs Music ElevenLabs Music's strength is structured songs with real vocals — it takes a style brief plus lyrics with section markers and returns a coherent, mixed track. Pick it for: Full vocal songs — verse/chorus structure, multilingual lyrics, consistent meter Instrumental beds — force instrumental: true for background music, podcast intros, game loops Short brand assets — jingles, stingers, theme music (5–30 s) Long form tracks — up to 5 minutes in a single call Commercial work — output is commercial friendly If the user just wants ambient sound or a one off SFX (thunder, footsteps), that's a sound effects task, not music — ElevenLabs Music is for songs and tracks . Endpoint + input schema Model : elevenlabs/elevenlabs/music generation Field Type Required Default Notes prompt string yes — Style description and lyrics with section markers.

The result JSON contains the generated audio URL — the CLI downloads it into output dir . Pricing : ~$0.0083 per second of generated audio (30 s ≈ $0.25, 60 s ≈ $0.50, 5 min ≈ $2.49). Cost scales with music length ms , so draft short and finalize long. How to invoke Full vocal song with structure: Instrumental background bed: Short brand jingle: Prompting tips ElevenLabs Music reads one prompt field that carries both the style brief and the lyrics. Structure it well: Lead with the style brief : genre, mood, tempo (BPM), key instruments, vocal type. "Upbeat indie pop anthem, bright electric guitars, 120 BPM, female lead vocal." Then the lyrics with section markers : [Intro] , [Verse] , [Chorus] , [Bridge] , [Outro] . Add approximate durations or bar counts — [Intro 8 bars] , [Verse 16 bars] . Keep lyrical meter consistent — even syllable counts per line, clear rhyme scheme. The model follows meter; sloppy meter produces awkward phrasing. Name lead instruments and mix priorities — "electric guitar carries the chorus, drums sit back in the verse." For instrumental , set force instrumental: true AND say "no vocals" in the prompt — belt and suspenders. Multilingual : write the lyrics in the target language; annotate accent/language inline if needed ( [Verse] (sung in Brazilian Portuguese) ... ). Avoid contradictory style instructions — "aggressive metal" + "soft lullaby" in one prompt confuses the model. One coherent direction per call. Draft short, finalize long : validate the direction with a 30–45 s draft ( music length ms: 35000 ) before paying for a 5 minute render. Common patterns Theme song for a video Full brief + lyrics + [Intro]/[Verse]/[Chorus] structure, music length ms matched to the video length Podcast intro / outro force instrumental: true , 10–20 s, "loop friendly, clean ending" Game background loop force instrumental: true , describe "seamless loop", 60–120 s, consistent groove Multilingual release (same song, multiple languages) One call per language, identical style brief, swap only the lyric lines Iterate then commit Draft at music length ms: 35000 to lock genre/tempo/structure → final render at full length Limitations One prompt field carries everything (style + lyrics). There is no separate "lyrics" parameter. 5 s – 5 min per call ( music length ms 5000–300000). For longer pieces, generate sections and stitch externally. Cost scales with duration — a 5 minute render is ~10× a 30 second one. force instrumental is the only vocal toggle — you can't request specific voice identities or clone a singer through this endpoint. This skill pins ElevenLabs Music specifically . For sound effects, text to speech, or voice cloning, that's a different ElevenLabs capability not exposed through this endpoint.

How it works The skill invokes runcomfy run elevenlabs/elevenlabs/music generation with the JSON body. The CLI POSTs to the RunComfy Model API, polls request status, fetches the result, and downloads the generated audio file into output dir . Ctrl C cancels the remote request before exit. Security & Privacy Install via verified package manager only. Use npm i g @runcomfy/cli or npx y @runcomfy/cli . Agents must not pipe an arbitrary remote install script into a shell on the user's behalf — if the operator wants the curl pipe path documented at docs.runcomfy.com/cli/install , they should review the script first. Token storage : runcomfy login writes the API token to ~/.config/runcomfy/token.json with mode 0600. Set RUNCOMFY TOKEN env var to bypass the file in CI / containers. Never echo the token into a prompt, log it, or check it in. Input boundary (shell injection) : the prompt is passed as a JSON string via input . The CLI does not shell expand prompt content; it transmits the JSON body directly to the Model API over HTTPS. No shell injection surface from prompt content , even with backticks, quotes, or $(...) patterns. Lyrics provenance : if the user supplies lyrics, confirm they have the rights to them. Generating music around copyrighted lyrics is the operator's responsibility — the skill does not check. Outbound endpoints (allowlist) : only model api.runcomfy.net (request submission) and .runcomfy.net / .runcomfy.com (download whitelist for generated audio). No telemetry, no callbacks. Generated file size cap : the CLI aborts any single download 2 GiB. Scope of bash usage : the skill only invokes runcomfy <subcommand — npm / npx lines are one time operator setup, not commands the skill executes per call.
