Music Generation Skill

Generate music, songs, and audio using AI (Suno, Udio, Google Lyria).

Prerequisites

At least one API key is required:

• GOOGLE_API_KEY - For Google Lyria (same key as video/image) ✅
• SUNO_API_KEY - For Suno music generation
• UDIO_API_KEY - For Udio music generation

Available APIs

Google Lyria (Instrumental Only)

• Best for: Background music, beats, soundtracks, game audio
• Duration: Any length (streams in real-time)
• Features: BPM control, key/scale, brightness, density
• Output: 48kHz stereo WAV
• API Key: Same GOOGLE_API_KEY as video/image generation ✅
• ⚠️ INSTRUMENTAL ONLY - Cannot generate vocals

Suno (Recommended for Songs with Vocals)

• Best for: Full songs with vocals, catchy melodies, various genres
• Duration: Up to 4 minutes
• Features: Lyrics generation, instrumental mode, style tags

• Duration: Up to 2 minutes per generation
• Features: Style control, audio quality options
• Genres: Wide variety with strong electronic/experimental support

Workflow

Step 1: Ask Key Question - Vocals or Instrumental?

This determines which API to use:

Example prompt to user:

"I'll generate that music! Quick question:

1. Do you need vocals/lyrics?

   • Yes → I'll use Suno (best for songs)
   • No, instrumental only → I'll use Lyria (same key as video/image)

2. What genre/mood? (e.g., chill lo-fi, epic orchestral, upbeat pop)

3. How long? (Lyria: any length, Suno: up to 4 min)

4. Any BPM preference? (e.g., 90 for chill, 128 for dance)"

Step 2: Understand the Request

Parse the user's music request for:

• Genre/style: Pop, rock, jazz, electronic, classical, etc.
• Mood: Happy, sad, energetic, calm, dramatic
• Tempo: Fast, slow, medium, specific BPM
• Vocals: With vocals → Suno/Udio, Instrumental → Lyria
• Purpose: Background music, song, jingle, soundtrack
• Duration: How long should it be?

Step 2: Craft the Prompt

Transform the user request into an effective music generation prompt:

1. Specify genre: Be specific about the style
2. Describe mood: Emotional tone and energy level
3. Include instruments: What should be prominent
4. Add production style: Lo-fi, polished, vintage, modern
5. Set tempo: BPM or descriptive (upbeat, slow)

Example transformation:

• User: "happy summer song"
• Enhanced: "Upbeat indie pop song with bright acoustic guitar, cheerful ukulele, and sunny vibes. Feel-good summer anthem with catchy hooks and positive energy. Male vocals, 120 BPM, radio-friendly production"

Step 3: Handle Lyrics (If Needed)

For songs with vocals:

• User provides lyrics: Use them directly
• Generate lyrics: Ask Suno/Udio to generate, or use Claude to write them first
• Instrumental: Specify "instrumental" to skip vocals

Lyrics format for Suno:

[Verse 1]
Your lyrics here

[Chorus]
Catchy chorus lyrics

[Verse 2]
More lyrics

Step 4: Select the API

Choose based on requirements:

Step 5: Generate the Music

Execute the appropriate script from ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/:

For Google Lyria (Instrumental):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "chill lo-fi hip hop, jazzy piano, vinyl crackle" \
  --duration 60 \
  --bpm 85

Lyria with key/scale:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "ambient, ethereal synths, dreamy" \
  --duration 120 \
  --scale "C" \
  --brightness 0.7

Lyria with multiple prompts (blended):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/lyria.py \
  --prompt "minimal techno" \
  --prompt "deep bass, 808" \
  --bpm 128 \
  --duration 90

For Suno (with vocals):

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/suno.py \
  --prompt "upbeat indie pop, summer vibes, acoustic guitar" \
  --title "Summer Days"

For Udio:

python3 ${CLAUDE_PLUGIN_ROOT}/skills/music-generation/scripts/udio.py \
  --prompt "cinematic orchestral, epic trailer music" \
  --duration 120

Step 6: Deliver the Result

1. Provide the generated audio file path
2. Share the prompt and settings used
3. Mention the duration and format
4. Offer to:
   • Generate variations
   • Try different style/genre
   • Adjust tempo or mood
   • Extend the track
   • Add or remove vocals
