The skill document
Music Generation - Original Music, Fully Yours
Music generation — 5 seconds to 10 minutes. Instrumental and vocal tracks with high-quality AI vocals.
Generated tracks are royalty-free for commercial use per CellCog's terms of service — YouTube, podcasts, apps, games, ads, films, streaming.
How to Use
For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.
OpenClaw (fire-and-forget):
result = client.create_chat(
prompt="[your task prompt]",
notify_session_key="agent:main:main",
task_label="my-task",
chat_mode="agent",
)
All agents except OpenClaw (blocks until done):
from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
prompt="[your task prompt]",
task_label="my-task",
chat_mode="agent",
)
print(result["message"])
Two Ways to Create Music
Simple Prompt (Use This 99% of the Time)
Just describe what you want. The model handles the rest — genre, arrangement, instrumentation, dynamics, and even lyrics:
"Compose a 90-second cinematic score. Start with solo piano, layer in strings at 30 seconds, build to a full orchestral swell, then resolve softly. Mood: bittersweet turning hopeful."
"Create a 3-minute lo-fi hip-hop track with soft piano, vinyl crackle, and mellow drums. 75 BPM. Study vibes."
"Write a 2-minute upbeat pop song with female vocals about starting fresh on a Monday morning. Catchy chorus, feel-good energy."
The model is exceptionally sophisticated — it handles any genre, genre fusion, songs with lyrics, complex arrangements, and mood transitions from a simple description.
Composition Plan (For Precise Timing Control)
Only use this when you need exact section durations — for example, syncing music to specific video segments or presentation slides:
"I need music that syncs with my video:
- Intro: exactly 10 seconds, soft ambient
- Build: exactly 20 seconds, energy rising
- Climax: exactly 15 seconds, full orchestra
- Outro: exactly 10 seconds, gentle fade"
This mode gives precise timing control per section but should only be used when timing accuracy matters for syncing with other media.

Chat Mode
Use chat_mode="agent" for music generation. Music executes well in agent mode.
Example Prompts
Cinematic score:
"Compose a 2-minute cinematic score for a nature documentary finale. Begin with solo cello (melancholic), layer in strings and piano at 40 seconds, build to a hopeful orchestral swell, resolve with gentle piano. Think Planet Earth meets Interstellar."
Lo-fi background:
"Create 5 minutes of lo-fi study beats. Soft piano, mellow drums, vinyl crackle, gentle bass. 75 BPM. Warm and unobtrusive — good for focus."
Podcast intro + outro:
"Create a podcast intro (8 seconds) and outro (6 seconds). Show is a tech startup podcast. Intro: energetic, modern electronic with a hook. Outro: same vibe but mellower wind-down. Should feel like the same show."
Song with vocals:
"Write a 3-minute upbeat indie pop song with female vocals. Theme: the excitement of moving to a new city. Catchy chorus, acoustic guitar foundation, builds with drums and synth. Feel-good, sing-along energy."
Game soundtrack:
"Compose a 2-minute boss battle theme for a fantasy RPG. Intense orchestral with choir, driving percussion, escalating tension. Think Dark Souls meets Final Fantasy."
Tips
-
Describe the feeling, not just the genre: "Music that makes a startup pitch feel like the future" works better than "electronic music."
-
Specify duration: "45 seconds" vs "3 minutes" changes composition structure significantly.
-
Reference moods, not copyrighted songs: "Hans Zimmer-style epic" and "ChilledCow lo-fi vibes" work well. Do not reference specific copyrighted songs.
-
For vocals: Set the lyrical theme and mood. The model writes lyrics that fit. Or provide specific lyrics you want sung.
-
Energy arc matters: "Starts quiet, builds at midpoint, resolves softly" gives clear compositional structure.
-
For video background music: If the music is for a CellCog video, mention it in your video prompt instead — CellCog handles music as part of video production automatically.

Questions people ask
- Can it create both instrumental music and songs with vocals?
- Yes. Prompts can request instrumental tracks or AI-vocal songs; for vocals, provide a lyrical theme and mood, or supply specific lyrics to be sung.
- How much control do I have over duration and structure?
- Tracks can run from 5 seconds to 10 minutes. A simple prompt can define the overall arc, while a composition plan can assign exact durations to sections for video or slide synchronization.
- What file format and usage rights do generated tracks have?
- The output is MP3 at 44.1 kHz and 128 kbps. Generated tracks are royalty-free for commercial uses such as podcasts, games, apps, ads, films, streaming, and YouTube, subject to CellCog’s terms of service.
