# Best Suno prompts for metalcore

Updated 2026-09-22

The best metalcore prompts name the breakdown (a slow, heavy, chugging section), the drop-tuned guitar sound, the double bass drum pattern and how the vocals switch between harsh and clean. Use: "metalcore, drop-tuned chugging guitars, double bass drum, breakdown at half tempo, harsh screamed verse, clean sung chorus, tight low-end mix, aggressive mood, 150 BPM".

Suno and Udio read genre and instrument words more reliably than they follow exact structure, so naming the breakdown and the vocal switch is more useful than describing riffs in technical detail.

## How do you get the breakdown to sound right?

Name the breakdown directly and say it slows down: "breakdown at half tempo" or "half-time double bass drum" tells the model to drop the pace and add weight, rather than just repeating the same speed with heavier guitars. Pairing this with "drop-tuned chugging guitars" describes the low, choppy palm-muted sound that defines the section without needing guitar tuning names.

## How do you prompt the switch between harsh and clean vocals?

State the vocal style separately for each section: "harsh screamed verse, clean sung chorus" is more reliable than one blended description like "aggressive melodic vocal". Suno and Udio follow vocal timbre words such as screamed, growled, raspy and clean fairly well, but they do not reliably time an exact switch mid-line, so expect to regenerate a few times to get the contrast where you want it.

| Vocal word | What it gets you |
|---|---|
| harsh screamed | aggressive, distorted verse vocal |
| growled | lower, guttural verse vocal |
| clean sung | melodic, in-tune chorus vocal |
| falsetto | higher, thinner clean vocal for contrast |

## What tempo and drum pattern words work for metalcore?

Metalcore commonly sits at 140 to 180 BPM for verses and choruses, with breakdowns often implied at half that speed by saying "breakdown at half tempo" rather than giving two separate numbers. Always name "double bass drum" directly, since it is the drum pattern most associated with the genre's driving, relentless feel; without it, the model may default to a plainer rock beat.

## Should you describe the guitar tuning?

Say "drop-tuned" or "down-tuned" rather than naming a specific tuning like drop C, since the model responds to the general low, heavy character rather than exact pitch instructions. Add "chugging" or "palm-muted" to describe the rhythmic, percussive guitar sound that sits under the drums, which is a bigger part of the metalcore identity than any single tuning choice.

## Lyrics skeleton

Original, for structure

[Verse]
Walls close in, I count the cracks
Every step is a step back

[Breakdown]
Hold the line, hold the weight
Nothing left to hesitate

[Chorus]
We rise above the fall
Still standing after all

[Outro]
Echo fades, the silence stays

## Common mistakes

- Writing just "metal" or "heavy music" instead of "metalcore", which loses the specific breakdown and vocal-switch identity; name the genre directly.
- Asking for both vocal styles in one phrase like "screamed and clean vocal" with no section split, which often blends into a muddy in-between sound; describe each section’s vocal separately.
- Mixing contradictory moods such as "uplifting, dark, aggressive" all at once, which confuses the output; pick one dominant mood and at most one secondary one.
- Adding exact tuning names or technical guitar jargon expecting precision, which the model does not reliably follow; use "drop-tuned" and "chugging" instead.
- Leaving out the double bass drum, which results in a slower, more generic rock beat; name it explicitly if it matters to the track.

## Questions

### What BPM should I use for a metalcore prompt?

140 to 180 BPM covers most metalcore verses and choruses, with 150 to 160 BPM a common middle choice. For a breakdown section, describe it as half tempo rather than giving a separate lower number, since the model reads that instruction more reliably than a second BPM figure.

### How do I prompt a breakdown in Suno or Udio?

Name it directly: "breakdown at half tempo" combined with "drop-tuned chugging guitars" and "double bass drum". Square-bracket tags such as [Breakdown] in the lyrics box are a common convention the model often follows, though not always, so treat it as a strong hint rather than a guarantee.

### Can I ask for screamed and clean vocals in the same song?

Yes, describe them per section rather than together: "harsh screamed verse, clean sung chorus". This gives clearer contrast than one combined vocal description and is closer to how metalcore actually alternates between the two styles.

### Why does my metalcore prompt come out sounding like generic rock?

This usually happens when the prompt is missing the specific drum and guitar words that separate metalcore from plain rock, such as double bass drum and drop-tuned chugging guitars. Add those terms and name the breakdown directly to steer the output away from a generic rock default.

### Does naming the guitar tuning like drop C actually help?

Not reliably. General terms like drop-tuned or down-tuned describe the low, heavy character the model can act on, while exact tuning names function more like technical labels it tends to ignore. Focus on the sound description instead of the precise tuning.

### Should I use an exclude field for metalcore prompts?

If your tool has one, use it to keep out unwanted styles such as pop, clean radio-friendly vocal, or acoustic, which can otherwise creep into a metalcore render. This is more useful than trying to over-describe what you do not want inside the main prompt.

### How does Lyro Music handle a metalcore prompt like this?

Lyro Music turns a description like this into a mixed and mastered track, routing tempo-locked beats and audio-input work to ACE-Step 1.5 and sung lyrics to Google's Lyria 3 Pro. You can build a prompt like the ones above for free at the prompt generator, and tracks run 30 seconds to 3 minutes.
