FAL Music - AI Music Generation

Generate music using FAL.ai — access to Stable Audio Open, Stable Audio 2.5, and Beatoven Maestro through a single API.

Setup

Uses the same FAL API key as fal-video-skill. If not already configured:

python3 ~/.claude/skills/fal-music-skill/fal_music_skill.py config YOUR_API_KEY

Or set environment variable:

export FAL_KEY="your_api_key"

Commands

Generate Music

python3 ~/.claude/skills/fal-music-skill/fal_music_skill.py generate "your prompt" [OPTIONS]

Arguments:

• PROMPT - Music description (e.g., "dark synthwave with driving bass and arpeggiated synths")
• --model, -m - Model to use (default: stable-audio-25)
• --duration, -d - Duration in seconds (default: 60)
• --steps, -s - Inference/refinement steps
• --guidance, -g - Guidance scale (stable-audio-25 only)
• --creativity - Creativity level 1-20 (beatoven only)
• --negative-prompt, -n - What to avoid (beatoven only)
• --seed - Random seed for reproducibility
• --output, -o - Output file path
• --timeout, -t - Timeout in seconds (default: 300)

Examples:

# Synthwave track
python3 fal_music_skill.py generate "dark synthwave instrumental, driving bassline, analog arpeggios, 120 BPM" -d 90

# Ambient music with Beatoven
python3 fal_music_skill.py generate "ambient electronic, atmospheric pads, gentle evolving textures" -m beatoven -d 120

# Short loop with Stable Audio Open
python3 fal_music_skill.py generate "128 BPM techno drum loop with acid bass" -m stable-audio -d 30

# Custom output path
python3 fal_music_skill.py generate "epic orchestral trailer music" -o ~/music/trailer.wav

Prompt Tips

Good prompts for music generation:

• Include genre: "synthwave", "ambient", "techno", "orchestral"
• Specify tempo: "120 BPM", "slow tempo", "driving rhythm"
• Mention instruments: "analog synths", "electric guitar", "piano"
• Describe mood: "dark", "uplifting", "melancholic", "energetic"
• Add "instrumental" to avoid vocals

Requirements

requests>=2.28.0

Security Notes

• API key stored in config.json with 600 permissions
• Falls back to fal-video-skill config if own config not set
• Audio files downloaded locally, URLs expire after ~24 hours
