🎯 What You'll Achieve
Quick Navigation
1. The Art of Prompt Engineering
The prompt is the most critical factor in AI music generation. A vague prompt yields vague results. Here's how to craft prompts that deliver:
✍️ The Ultimate Prompt Formula
Formula: Genre + Mood + Instruments + Vocal Style + BPM/Tempo
"A sad song about love"
"Melancholic indie folk ballad, acoustic guitar and cello, soft female vocals, slow tempo 70 bpm, emotional atmosphere, reverb"
🔑 Key Descriptors to Use
- Genre Blends: "Cyberpunk Synthwave", "Orchestral Dubstep", "Lo-fi Jazz Hop"
- Atmosphere: "Ethereal", "Gritty", "Uplifting", "Dark", "Dreamy"
- Production Quality: "High fidelity", "Studio quality", "Raw", "Live performance"
- Vocal Type: "Male baritone", "Female soprano", "Choir", "Auto-tuned", "Whispery"
2. Mastering Style Selection
HeartMuLa offers preset styles, but customizing them is where the magic happens.
🎵 Trending Combinations
- Pop + EDM: Catchy hooks with energetic drops
- Rock + Orchestral: Epic, cinematic impact
- R&B + Lofi: Chill, soulful vibes
- Metal + Synth: Industrial, aggressive energy
💡 Pro Tip: Negative Prompts
If your generation sounds too busy or chaotic, try adding descriptions of what you don't want in your mind, or phrase your positive prompt to exclude them (e.g., "Minimalist accompaniment" instead of "No drums").
3. Structuring Metrics & Lyrics
AI models understand song structure tags. Using them correctly helps the AI build a coherent song layout.
📌 Essential Tags
[Intro]- Instrumental start or build-up[Verse]- Storytelling sections[Chorus]- Look for catchy, repetitive hooks[Pre-Chorus]- Build tension before chorus
[Bridge]- Change in rhythm/melody[Solo]- Instrumental breakdown[Outro]- Fading out or final notes[Drop]- High energy (EDM)
4. Using Instrumental Breaks
Don't clutter every second with vocals. Let the music breathe.
How to Force Instrumentals
Use the [Instrumental] tag or simply leave a section of lyrics
blank while describing the instrumental solo in the style prompt.
- Example: Add "Electric guitar solo, high energy" to style prompt during a bridge.
- Benefit: Creates dynamic contrast and makes the chorus hit harder.
5. Optimal Generation Settings
Model Selection
Always use the latest model version available (e.g., v3 or v3.5) for the best audio fidelity and prompt adherence.
Clip Duration
Generating in shorter segments (extension mode) often yields better coherence than trying to generate a full 4-minute song in one shot.
6. Common Mistakes to Avoid
🚫 Top 5 Quality Killers
- Overcrowded Prompts: Asking for "Jazz Metal rap opera" usually results in noise. Stick to cohesive styles.
- Ignoring Structure: Not using [Verse]/[Chorus] tags leads to rambling, structureless songs.
- Bad Syntax: Keep prompts comma-separated. Avoid long complex prose sentences in style prompts.
- Repeating Lyrics: Don't paste the entire song lyrics at once if generating clip-by-clip.
- Giving Up Too Soon: AI generation is iterative. Re-roll the same prompt 3-4 times to find the "golden" seed.
7. Extending & Finishing Songs
Found a great 30-second clip? Don't stop there.
The Extension Workflow
- Take your best generated clip (e.g., Verse 1 + Chorus).
- Select "Extend" from the last second.
- Change the lyrics to Verse 2.
- Keep the style prompt consistent, or slightly modify it (e.g., remove "intro").
- Generate and stitch. Repeat until the Outro.
