MiniMax Music Maker

Use this skill to generate music with MiniMax's Music Generation API. All usage and outputs are designed for music-2.5 unless specified otherwise.

Quick start

1. Set the API key:

export MINIMAX_MUSIC_API_KEY="your_api_key"

2. Generate music from lyrics (and optional prompt):

python scripts/generate_music.py \
  --lyrics "[Verse]\n...\n[Chorus]\n..." \
  --prompt "indie folk, melancholic, introspective" \
  --output ./output.mp3

Script location

• scripts/generate_music.py — main generator (lyrics + prompt → audio)
• scripts/utils_audio.py — hex decoding + save helpers

References

Read references/minimax_music_api.md for:

• Endpoint, auth header, payload schema
• Required/optional fields
• Output formats (hex/url) and constraints

Core Modes

This skill supports 3 generation modes:

1. Standard Song (with lyrics)

• User provides or wants lyrics + music
• Use structured lyrics with prompt for style

2. Pure Music (Instrumental)

• User requests: "纯音乐", "纯音乐，无人声", "pure music", "instrumental"
• No lyrics, just instrumental arrangement
• See "Pure Music Generation" section below

3. Melodic Chanting/Humming

• User requests: "哼唱", "吟唱", "humming", "chanting"
• Music with vocal syllables instead of full lyrics
• See "Melodic Chanting Generation" section below

Notes

• lyrics is required by the API.
• prompt is optional for music-2.5.
• output_format defaults to hex (inline audio). Use url if you prefer a download URL.
• URLs expire (24h). Download immediately if using url.

Prompt crafting (Important)

Core Principles: Use "descriptions" instead of "commands", keep it structured, clear, and parseable.

Required Elements (Recommended)

• Genre/Subgenre (with era or region)
• Mood/Emotion (2-3 emotional descriptors)
• Tempo/BPM (specify BPM if possible)
• Key Instruments (3-5 key instruments/timbres)
• Vocals (vocal type, processing, or instrumental)
• Use case (purpose/scene)

Optional Enhancements

• Structure (section structure)
• References (1-2 style references)
• Avoid/Negative (exclusions)

Prompt Templates

Basic Template (Beginner)

[Genre], [Mood], [Tempo/BPM], [Key Instruments], [Vocal Style]

Standard Template (Recommended)

Genre: [Specific genre + era]
Mood: [2-3 descriptors]
Tempo: [BPM or speed]
Instruments: [3-5 key instruments]
Vocals: [Type or instrumental only]
Use case: [scene/usage]
Avoid: [unwanted elements]

Mood: ... (can include emotional arc, e.g., "from restrained to explosive")
Lead: …
Rhythm: …
Bass: …
Texture: …

Structure Tags (in lyrics)

[Chorus]
[Bridge]
[Outro]

Negative Prompt Examples

• No vocals / Instrumental only
• Avoid autotune
• No distorted guitars
• Avoid heavy reverb
• No trap hi-hats

Common Issue Fixes

• Style inaccurate: Add "era + sub-genre + instrument anchors + reference artists"
• Rhythm wrong: Specify BPM + rhythm description (e.g., four-on-the-floor)
• Intro too generic: Write [Intro] in lyrics and describe the opening
• Vocals off: Move Vocals to front of prompt and add negative constraints

Prompt Quality Checklist

• Contains: Genre / Mood / BPM / Instruments / Vocals / Use case
• Check for conflicts (e.g., "very slow + high energy")
• Has Avoid items to filter unwanted elements
• Is structured (avoid long prose paragraphs)
