Mureka Music Maker

Skywork Music Maker (Mureka API)

Generate professional-quality music using the Mureka API at https://api.mureka.ai. This skill covers the complete music production workflow: lyrics writing → song/instrumental generation.

First-Time Setup

Before running any API command, check if MUREKA_API_KEY is set. If not, guide the user to get an API key at https://platform.mureka.ai/ (register → API Keys → generate key → export MUREKA_API_KEY="..."), then STOP — do not attempt any API calls until the key is configured.

Smart Prompt Conversion (CRITICAL WORKFLOW)

Default behavior: When the user doesn't specify song type, always generate a song with lyrics (use mureka.py song). Only use mureka.py instrumental when the user explicitly asks for instrumental, BGM, background music, or "no vocals".

Output defaults: Use mp3 format unless the user requests otherwise. The --output flag specifies a directory — the script creates it and saves all results inside (audio files + lyrics.txt for songs). If the user doesn't specify a location, choose a user-friendly path with a descriptive folder name based on the song theme (e.g., summer_pop_song/).

When users provide music descriptions in natural language (in any language), you MUST convert them to structured Mureka API prompts using this workflow:

Conversion Process

User Input Examples:

• "upbeat pop song, female vocals, guitar, perfect for summer"
• "sad piano ballad about lost love"
• "epic orchestral music for a fantasy game"
• "traditional Chinese music with bamboo flute and zither, misty atmosphere"

Your Task:

1. Extract structured parameters using the extraction rules below
2. Validate the prompt meets quality standards (see Quality Checklist)
3. Present to user for confirmation before generating
4. Run the generation command with the structured prompt

Parameter Extraction Rules

When users provide natural language music descriptions, directly extract and structure the following parameters:

Required Parameters:

• genres: music genres including fusion styles (e.g., Pop, Rock, Jazz, Pop Rap Fusion, Alternative Rock, Guofeng)
• moods: emotional tones (e.g., Happy, Melancholic, Energetic, Nostalgic, Bright)
• instruments: specific instruments (e.g., Piano, Guitar, Drums, Erhu, Guzheng, Synth Pads, Dizi)
• rhythms: rhythm characteristics (e.g., 4/4, Slow, Syncopated, Driving, Flowing)
• vocals: vocal attributes (e.g., Female, Husky, Whispered, Male, Soft, Clear) or "instrumental only"
• key: musical key if specified (e.g., C Major, A Minor, C# Major)
• bpm: beats per minute (e.g., 120) or tempo descriptor (e.g., "slow groove", "uptempo")
• description: concise summary (under 50 words) capturing mood progression, melody, harmony, timbre, texture, dynamics

Extraction Instructions:

1. Translate non-English terms: Convert ALL non-English musical terms to English while preserving cultural and musical meaning
2. Preserve specificity: Keep detailed information including specific styles, subgenres, and cultural context (e.g., "Chinese traditional guofeng" not just "Chinese music")
3. Design dynamic arc: Include mood progression where appropriate (e.g., "sparse opening → building tension → cathartic chorus")
4. Infer intelligently: Make reasonable assumptions based on genre conventions when parameters are not explicitly stated
5. English output: Final prompt string MUST be entirely in English

Generate Structured Prompt: Combine all extracted parameters into a comprehensive, natural-flowing description that captures the essence of the user's vision.

Quality Checklist (Validate BEFORE Generation)

Before running the generation command, verify the prompt meets these criteria:

MUST HAVE:

• Specific genre (NOT "pop song" but "synth-pop, 2020s")
• BPM or tempo descriptor (e.g., "120 BPM" or "slow groove")
• 3-5 instruments explicitly named
• Mood/emotion descriptors (2-3 words)
• Vocal style (or "instrumental only")
• Structure tags in lyrics: [Verse], [Chorus], [Bridge], [Outro]

WATCH OUT FOR:

• Vague terms: "nice", "good", "beautiful" → replace with specific descriptors
• Contradictions: "slow" + "energetic", "sad" + "uplifting" → pick one direction
• Too short: <50 chars → add more detail
• Long lyric lines: >10 words per line → split into shorter lines
• No dynamic arc: add mood progression (e.g., "sparse → building → full")

AVOID:

• Command verbs: "create a song" → use descriptions "upbeat pop song"
• Famous artist names: "sounds like Taylor Swift" → describe qualities instead
• Unrealistic combos: melody_id cannot combine with other control options

After validation, present the generated prompt to the user for confirmation before proceeding.

Core Workflow: Production Pipeline

1. Conceptualize → User describes in natural language → YOU convert to structured prompt
2. Validate → Check prompt quality against Quality Checklist (see above)
3. Write Lyrics → Use lyrics/generate or write manually
4. Upload References → Optional: reference track, vocal sample, melody
5. Generate → Submit song/instrumental task (async) with validated prompt
6. Evaluate → Listen to all N choices, pick best
7. Iterate → Refine prompt based on what you heard

Critical Steps:

• Step 1 is mandatory when user provides natural language input (especially non-English)
• Step 2 validation prevents 80% of common generation failures
• Step 3: Read references/prompt_guide.md for prompt crafting examples, lyrics structure rules (line length, syllable count, rhyme patterns, hook writing), and iteration best practices
• Do NOT skip conceptualization — jumping straight to generation without a clear concept is the #1 reason for generic results

Your Role as AI Assistant:

1. Convert user's natural language → structured Mureka prompt (using Smart Prompt Conversion)
2. Validate prompt quality → flag issues → suggest fixes
3. Write or generate lyrics with proper structure
4. Present prompt to user for confirmation
5. Execute generation command with validated prompt
6. Help iterate and refine based on generation results
