Quickstart: Writing Your First SGM4 Music Prompt

If you’ve ever typed “trap beat, dark, 140 BPM” into Suno and gotten something that almost — but not quite — sounded like what you wanted, this is for you.

SGM4 (SUNO God Mode 4) isn’t a magic button. It’s a systematic way to describe music to an AI so it gives you back something that respects your intention. This quickstart covers the core formula. The full system has 10 modules and 222 ontology points, but you don’t need all of that to start getting better results.

The Formula

[Genre Tags] — [Mood/Atmosphere] — [Tempo/Key] — [Instrumentation] — [Structure] — [Production Notes]
```text
Each section matters. Skip one and Suno fills the gap with its own assumptions — which is exactly what leads to generic output.

## Step 1: Choose Your Genre

Start with 2–3 genre tags from the taxonomy. Be specific. "Electronic" is worthless. "Dark trap, phonk influence" is direction.

**Electronic:** `dubstep`, `trap`, `future bass`, `house`, `drum and bass`, `phonk`, `melodic trap`

**Rock/Metal:** `post-rock`, `metalcore`, `shoegaze`, `alternative`

**Experimental:** `glitch`, `ambient`, `breakcore`, `industrial`

**Example:** `dark trap, phonk, industrial`

## Step 2: Set the Mood

Describe the emotional tone with adjectives that actually affect sound:

- `dark`, `cinematic`, `aggressive`, `melancholic`, `euphoric`
- Combine: `dark cinematic, melancholic euphoria`

Avoid vague emotional words like "sad" or "happy." Suno doesn't know what sadness sounds like — but it knows what `minor key, reverb-heavy, slow attack synths` sounds like.

## Step 3: Tempo & Key

Be specific or intentionally loose:

- `140 BPM, F minor`
- `fast, aggressive tempo`
- `mid-tempo groove, no specific key`

Key matters more than most people think. A track in `D minor` vs `F# minor` hits differently even at the same tempo.

---

## Step 4: Call Out Instruments

List what you want to hear. This is where you fight generic production:

- `heavy sub-bass, glitched synths, distorted 808s, cinematic percussion`
- `analog pads, tape-saturated drums, FM bells`

The more specific your instrumentation, the less Suno defaults to its training-data average.

---

## Step 5: Describe the Structure

Give Suno a roadmap. It understands basic structural language:

- `intro → build → drop → breakdown → build → double drop → outro`
- `verse → chorus → bridge → chorus → outro`

For vocal tracks, use metatags: `[Verse]`, `[Chorus]`, `[Bridge]`, `[Hook]`, `(adlib)`.

---

## Step 6: Production Notes

The secret sauce. These are the details that separate amateur prompts from professional ones:

- `wide stereo field, vinyl crackle, sidechain compression`
- `reverb tails, tape saturation, aggressive limiting`
- `intimate close-mic'd vocals, room ambience`

## Full Example Prompt

```text
dark trap, phonk, industrial — dark cinematic, aggressive melancholy —
140 BPM, F minor — heavy sub-bass, glitched synths, distorted 808s,
cinematic percussion, analog pads — intro → build → drop → breakdown →
build → double drop → outro — wide stereo field, sidechain compression,
vinyl crackle, aggressive mastering, reverb tails

## Iteration Strategy

1. **Generate** with your first prompt
2. **Listen** for what's wrong — not what's right
3. **Change 1–2 parameters** at a time (never everything)
4. **Save winning prompts** to a library — you'll reuse them
5. **Share results** and compare notes

## What's Next

This is the quickstart. The full SGM4 system covers:

- **B.A.R.S. lyric framework** — structured lyrics by Bars, Articulation, Rhyme, Syllables
- **Metatag sequencing** — proper `[Verse]` / `[Chorus]` / `(adlib)` placement
- **Genre taxonomy** — 8 primary buckets, 40+ subgenres, 15% genre cap rule
- **Sound engineering layer** — mix and FX descriptors baked into prompts
- **800+ keyword corpus** — searchable, filterable, expandable
