The Advanced Guide to Suno v6 prompting: Production Notes and Style Tags
You will finish this Suno v6 prompting tutorial with eight generated candidates and a reusable production brief. You will also save structured lyrics, two style prompts, and a scored listening log. The procedure assumes familiarity with Suno’s Create screen and basic terms such as verse, chorus, and BPM.
1. What you need
- A Suno Pro or Premier account with the core v6 model available.
- At least 40 credits for four standard, text-only generations, subject to the displayed creation cost.
- Suno’s desktop web interface, with Advanced mode available, called Custom in older documentation.
- A plain-text editor and a spreadsheet supporting CSV files.
- Headphones or speakers, with playback enhancement and automatic volume normalization disabled where available.
- An empty folder named
night-window-v6for the prompt files and listening log.
2. Step 1 — Configure a controlled Suno v6 prompting session.
Open Suno’s Create screen and select Advanced, or Custom if that label appears. Select v6 from the model dropdown near the Create form’s upper-right corner.
Do not select v6-wild or v6-mini for this comparison. Those variants change the model, adding another variable to your test.
Start a new song without uploaded audio, reference songs, images, or video. Leave any saved voice or persona unselected. Keep instrumental generation off because this exercise includes sung lyrics.
Open the creation controls and enter these starting values.
| Control | Value | |---|---| | Model | v6 | | Weirdness | 20% | | Style Influence | 75% | | Variety | 0 | | Max Mode | Off |
These are experimental starting values, not official presets. Suno documents Weirdness at 50% as its normal midpoint. The lower value here limits experimentation during comparison.
Variety can adjust the supplied style prompt. Setting it to 0 preserves control over your submitted style tags. Max Mode costs additional credits, so leave it off throughout this test.
Record these settings in settings.txt inside your project folder. Include the session date and the model label exactly as displayed.
Check: The form should show v6, your starting controls, and no attached reference material.
Steps, as measured in this article's example.
3. Step 2 — Write an audible production brief.
Create brief.txt and paste the following specification.
Project: Night Window.
Primary genre: Restrained synth-pop.
Tempo target: 104 BPM.
Meter target: 4/4.
Lead instrument: Muted analog synth pulse.
Bass: Rounded electric bass.
Drums: Tight electronic kick and snare.
Vocal: Low-register lead, restrained delivery, clear consonants.
Vocal placement: Centered, close, short room ambience.
Verse arrangement: Sparse, with exposed lead vocal.
Chorus arrangement: Wider synth layers and stronger drums.
Ending: Instrumental outro with a definite final stop.
Choose audible instructions rather than quality claims. “Short room ambience” supplies a clearer test than “professional vocals.” “Wider synth layers” describes a relationship between sections.
Keep tempo and meter labeled as targets. Generated audio may not follow either precisely. A written BPM value does not establish the actual tempo.
For this Suno v6 prompting exercise, freeze the brief before generating. Do not add guitars, orchestral layers, or another genre during the comparison.
Separate requirements from preferences in your notes. Treat complete lyrics and an intelligible lead as requirements. Treat exact tempo and stereo width as preferences requiring verification.
Check: Every brief entry should describe something you can hear, identify, or measure.
4. Step 3 — Build the lyrics and section map.
Create lyrics.txt and paste this original lyric block into it. Then paste the same block into Suno’s Lyrics field.
[Intro]
[Verse 1]
The last train shakes the window frame.
Your coffee cools beside my name.
I leave the hallway light awake.
And count the turns I did not take.
[Pre-Chorus]
The street below begins to glow.
I hold the words and let them go.
[Chorus]
Keep one light in the night window.
Let it burn where the cold winds blow.
I can leave without letting go.
Keep one light in the night window.
[Verse 2]
The morning waits behind the glass.
A silver bus goes rolling past.
I fold the map along its seam.
And wake the room from yesterday's dream.
[Pre-Chorus]
The street below begins to glow.
I hold the words and let them go.
[Chorus]
Keep one light in the night window.
Let it burn where the cold winds blow.
I can leave without letting go.
Keep one light in the night window.
[Bridge]
Leave the key beside the door.
I am not waiting anymore.
[Chorus]
Keep one light in the night window.
Let it burn where the cold winds blow.
I can leave without letting go.
Keep one light in the night window.
[Outro]
Keep section labels on separate lines. Keep production paragraphs out of the Lyrics field during this first comparison.
Bracketed labels provide arrangement guidance, not guaranteed timing commands. An [Intro] label does not establish a fixed number of bars.
Check that all three choruses contain identical wording. Repeated lyrics make omissions and substitutions easier to identify during playback.
Do not enter a precise duration requirement elsewhere. This test evaluates section behavior rather than a guaranteed runtime.
Check: The Lyrics field should contain the complete lyric block, including all three chorus labels.
5. Step 4 — Create the style-tag baseline.
Save the following text as style-A.txt. Paste it into the Style field, labeled Styles in some interfaces.
Restrained synth-pop, 104 BPM, 4/4, muted analog synth pulse, rounded electric bass, tight electronic kick and snare, low-register lead vocal, restrained delivery, clear consonants, centered close vocal, short room ambience, sparse verses, wider synth layers and stronger drums in choruses, instrumental outro, definite final stop.
This is the baseline for your Suno v6 prompting comparison. Each comma-separated phrase describes one part of the intended sound.
Open Advanced Options → Exclude and enter this exact list.
rap, distorted guitars, orchestral strings, crowd noise, long vocal reverb
Save that list as exclude.txt. Enter unwanted elements directly rather than writing “no rap” or “without guitars.”
Keep slider values outside the style text. Writing “Style Influence 75%” inside the prompt does not operate the interface control.
Do not add claims such as “award-winning production” or “perfect master.” Those phrases provide no specific listening criterion for this test.
Check: The Style field should contain desired characteristics, while Exclude contains only unwanted elements.
6. Step 5 — Generate and document the baseline pair.
Set the title to Night Window A. Confirm Weirdness 20%, Style Influence 75%, Variety 0, and Max Mode Off.
Check the displayed credit cost before clicking Create. Suno’s v6 FAQ lists two songs per standard generation for 10 credits. Additional inputs or enabled options can change costs.
Click Create once and wait for both candidates to become playable. Label them A1 and A2 in your notes.
Copy each candidate’s library link into a new spreadsheet. Create these columns in this exact order.
candidate,batch,model,weirdness,style_influence,variety,lyrics,groove,vocal,contrast,ending,total,notes,url
Enter A, v6, 20, 75, and 0 in the corresponding setup columns. Leave the five listening scores blank until Step 8.
Do not regenerate because the first introduction sounds different from your expectation. Play each candidate through its ending before identifying failures.
Check: Your library should contain two baseline candidates, with separate rows and saved links in the spreadsheet.
8. Step 7 — Test one control without rewriting the prompt.
Keep style-B.txt, the lyrics, and Exclude unchanged. Increase Style Influence from 75% to 90%.
Leave Weirdness at 20% and Variety at 0. Keep Max Mode Off and select the core v6 model.
Set the title to Night Window C. Click Create once, then record the pair as C1 and C2.
Enter 90 in their style_influence cells. All other setup cells should match the B candidates.
Style Influence controls adherence to the style input. A higher setting does not guarantee better lyrics, cleaner audio, or stronger musical results.
Do not change Weirdness during this batch. Otherwise, the comparison would mix two control changes.
Your Suno v6 prompting test now includes eight candidates across four generation batches. Under the documented standard cost, those batches total 40 credits.
Check: Only the Style Influence value should differ between the B and C configurations.
9. Step 8 — Score the candidates against the brief.
Listen at a fixed device volume. Compare the same sections across candidates before judging the complete songs.
Start with the first verse, then compare the first chorus. Finish by checking the final vocal line and outro.
Score each category from 0 to 2 using this rubric.
| Category | 0 points | 1 point | 2 points | |---|---|---|---| | Lyrics | Major omissions or substitutions. | Minor wording errors. | Supplied sung lines are intact. | | Groove | Target feel is absent. | Partially matches the brief. | Steady pulse and intended rhythmic feel. | | Vocal | Delivery or placement conflicts. | Some requested traits appear. | Restrained, clear, close lead. | | Contrast | Verse and chorus feel alike. | One clear arrangement change. | Both width and drum strength increase. | | Ending | Cutoff or unwanted continuation. | Outro appears, but stop is unclear. | Instrumental outro and definite stop. |
Add the five scores for a total out of 10. Do not award groove points solely because the prompt contains “104 BPM.”
For a tempo estimate, count beats across 30 seconds of steady drums. Multiply that count by 2 for approximate BPM. Half-time interpretations can produce a count near half the perceived pulse.
Record concrete notes such as “final chorus misses line three.” Avoid notes such as “better energy” without naming an audible difference.
Generated candidates have different performances and arrangements. Fixed device volume does not equal loudness-matched scientific testing. Avoid choosing a winner only because it sounds louder.
Check: Every candidate should have five scores, a total, and at least one specific listening note.
10. Step 9 — Save a reproducible prompt package.
Select the highest-scoring candidate that meets your lyric requirements. Break ties by choosing the closer vocal match.
If none meets those requirements, label the highest-scoring candidate best draft. Record its remaining defects rather than calling it finished.
Create winner.txt with these fields.
Candidate ID:
Library URL:
Session date:
Displayed model:
Style file:
Lyrics file: lyrics.txt.
Exclude file: exclude.txt.
Weirdness:
Style Influence:
Variety: 0.
Max Mode: Off.
Listening score:
Remaining defects:
Next single change:
Fill every field from the actual winning configuration. Export the spreadsheet as listening-log.csv.
For Next single change, name one audible issue and one corresponding adjustment. For excessive ambience, extend Exclude with long room tails. Keep other variables fixed during that later test.
Your Suno v6 prompting package should now contain both prompt variants and all evaluation records. It supports repeating the setup, not recreating identical audio.
Check: Another session should be configurable from your saved files without reconstructing settings from memory.
11. Troubleshooting
- Step 1: The core v6 model is missing. Check your subscription and the model dropdown. Core v6 requires Pro or Premier. Do not substitute v6-mini inside the same comparison log.
- Steps 4–6: Production directions become sung words. Check whether prose entered the Lyrics field. Restore
lyrics.txtthere and move production descriptions into Style. - Steps 6–7: The arrangement ignores your style wording. Confirm Variety remains at 0. Check the actual selected model and remove conflicting descriptors before funding another batch.
- Step 8: Choruses omit lines or rush syllables. Shorten the affected lyric line by two or three syllables. Save a new lyric version and begin a separate comparison.
- Steps 8–9: The ending fails despite a high total. Mark ending compliance as unresolved. Record
short instrumental outro, definite stopas the next isolated style change.
12. Tools
Valkat Studio covers lyrics, Suno prompts, vocal profiles, mastering, cover art, and music videos. Its audio-finishing tools include the mastering suite.
13. Final thoughts
Keep the winning prompt, control values, and audible exceptions together. Treat Suno v6 prompting as a documented comparison process, with one planned change per new test.
