Suno v6 gives you an Exclude field in Advanced Options—your negative prompt box. Instead of hoping Suno won't add a synth or auto-tune when you want organic folk, you list exactly what to leave out. This guide shows you how to use Suno negative prompts to control instruments, vocal effects, production styles, and genre elements that don't fit your track.
Where to Find the Exclude Field in Suno v6
Go to suno.com/create and choose Custom mode. Below the Style of Music box, click Advanced Options. The Exclude field appears alongside Vocal Gender, Weirdness, Style Influence, Variety, Max Mode, and Duration. This field is where all your negative prompts go—never put them inline in your style prompt.
The Exclude field accepts a comma-separated list. Suno hasn't published a character limit for this field, but the style box itself is capped at 1,000 characters. Keep your exclusions clear and specific: "auto-tune, synth pads, reverb, drum machine" works better than vague descriptions.
If you're building complex style prompts and want to test variations quickly, SONIQ's free Suno prompt generator lets you draft both positive and negative elements before you paste them into Suno's interface.
Common Instruments and Sounds to Exclude
Start with the instruments that clash with your genre or mood. If you're writing a stripped-down acoustic ballad, exclude electronic elements:
- synth, synthesizer, synth pads, synth bass
- drum machine, 808s, electronic drums
- auto-tune, vocoder, pitch correction
- electric guitar (when you want only acoustic)
- strings, orchestral strings (if you want raw, unpolished)
For hip-hop or trap that should stay minimal, exclude:
- live drums, acoustic drums
- guitar, piano
- choir, backing vocals
- reverb, echo (for dry, tight mixes)
For rock or punk that needs to stay aggressive, exclude:
- synth, electronic elements
- strings, orchestral
- acoustic guitar
- soft vocals, breathy vocals
Suno v6 was trained on a licensed catalog from Warner Music Group, BMG, and Believe, so it recognizes a wide range of instrument names. Use the terms musicians actually use: "808s" instead of "bass drum sound," "pad" instead of "sustained background tone."
Excluding Vocal Effects and Performance Styles
Vocal production can make or break a track. If you want natural, unprocessed vocals, exclude these effects:
- auto-tune, pitch correction, vocoder, talk box
- reverb, delay, echo
- distortion, vocal fry
- harmonies, backing vocals, choir
- whisper, breathy vocals, falsetto (when you want full voice)
You can also exclude performance styles that don't match your lyric content. For a serious, emotional ballad, exclude "rap, spoken word, shouting, aggressive vocals." For a clean pop track, exclude "screaming, growl, raspy vocals."
Suno's Advanced Options include a Vocal Gender toggle (Male or Female), so you don't need to exclude gender in the Exclude field—use the dedicated control instead. The Exclude field is for everything else about the vocal that you don't want.
Combining Vocal Excludes with Section Tags
Community practice uses bracketed tags like [Verse], [Chorus], and [Bridge] in the lyrics box. Some users report that v6 reads per-section performance cues in brackets—for example, [Verse, whispered]—but Suno's official documentation doesn't confirm this syntax. If you want a whispered verse but a full-voice chorus, try the section tag and also exclude "shouting, belting" in the Exclude field to keep the overall energy controlled.

Excluding Production Styles and Genre Elements
Sometimes you need to block entire production aesthetics. If you're making lo-fi hip-hop, exclude "polished production, compression, mastering." If you want a raw punk sound, exclude "studio polish, clean mix, pop production."
Genre bleed is common when your style prompt includes multiple influences. If you write "indie rock with folk elements," Suno might add country twang or bluegrass banjo. Exclude the specific elements you don't want:
- banjo, mandolin, fiddle (to avoid country/bluegrass)
- steel guitar, slide guitar (to avoid country)
- accordion, polka rhythm (to avoid folk clichés)
- brass, horn section (to avoid ska or big-band jazz)
For electronic genres, you can exclude specific sub-genre markers:
- dubstep wobble, brostep bass (for cleaner EDM)
- trance arpeggios, uplifting melody (for darker techno)
- breakbeat, jungle drums (for four-on-the-floor house)
Suno's Style Influence slider (Loose to Strong, default reportedly 50%) controls how strictly the model follows your style prompt. If you set it to Strong and still get unwanted elements, the Exclude field is your next tool. SONIQ's style prompt builder keeps prompts under 800 characters so the most important details lead, because Suno weighs the start of the style prompt most heavily.

Testing and Iterating with Negative Prompts
Suno v6 generates two songs for 10 credits total (unchanged from earlier versions). Use both takes to test whether your exclusions worked. If one take still includes the excluded element, regenerate with more specific language or add related terms. For example, if "synth" didn't work, try "synthesizer, synth pads, synth bass, electronic keyboard."
The Variety slider in Advanced Options controls take-to-take difference. Set it to 0 to keep your style prompt (and exclusions) unchanged across both takes. Higher Variety means Suno interprets your prompt more loosely, which can override some exclusions.
If you're working on a track longer than two minutes or need extra precision, Suno recommends Max Mode, which costs more credits but gives you better adherence to prompts and exclusions. Max Mode is also recommended for covers and style transfers.
Using Replace Section to Fix Excluded Elements That Slip Through
If an unwanted instrument appears in just one section, use Replace Section (Pro and Premier only). Triple-dot menu on the song, Edit, then Replace Section. Drag to highlight the problem section, edit the lyrics if needed, and click Recreate Section. You get two versions to choose from. This tool changes the middle of a song, unlike Crop, which only trims the start or end.
You can also add section-specific exclusions in the Replace Section workflow. If your chorus added strings you didn't want, highlight the chorus, leave the lyrics unchanged, and add "strings, orchestral" to the Exclude field in that edit.
Negative Prompts for Sampling and Mashups
Suno v6 introduced sampling from your own songs and mashups of tracks in your library. When you sample—say, "sample the riff at 0:45, isolate the guitar, build a beat around it"—you might want to exclude elements from the original that don't fit the new context. If you're sampling a guitar riff from a rock track to use in a hip-hop beat, exclude "live drums, bass guitar, vocal harmonies" so only the isolated riff carries over.
Mashups combine two of your own songs. Use the Exclude field to prevent clashing elements: if you're mashing a pop vocal with an electronic instrumental, exclude "acoustic guitar, live drums" to keep the electronic vibe clean. For more on sampling workflows, see How to Sample Your Own Songs in Suno.
Why Negative Prompts Matter for Consistency
If you're building a cohesive EP or album, negative prompts keep your sonic palette consistent. Decide at the project level which instruments and effects are off-limits, then use the same exclusions across all tracks. This is especially important if you're creating a Persona—a saved vocal and style profile from one of your songs. Personas fill the Style of Music box automatically when you select them, but they don't carry over exclusions. Add your standard exclusions manually each time you use a Persona.
Consistency also matters for hooks and memorable moments. If your chorus relies on a specific sound—say, a clean electric guitar with no effects—exclude "distortion, reverb, delay, chorus effect" to keep that hook sharp across every generation. For examples of hooks that define entire songs, see The 15 Best Song Hooks of All Time, Ranked.
FAQ
Can I use negative prompts in Simple mode?
No. Simple mode on Suno doesn't expose the Exclude field. You need Custom mode (suno.com/create, choose Custom) to access Advanced Options and the Exclude field. Simple mode only has a description box where you write your entire prompt inline.
Do negative prompts work on v6-wild and v6-mini?
Yes. All three v6 models—v6 (flagship), v6-wild, and v6-mini (the free model)—support the Exclude field in Custom mode. However, v6-wild is less predictable and more textured by design, so exclusions may be interpreted more loosely. Early testers report many v6-wild takes are unusable, so expect to regenerate more often even with precise exclusions.
What happens if I put negative prompts in the Style of Music box instead of Exclude?
Suno's engine treats inline negatives ("no synth," "without auto-tune") inconsistently. The Style of Music box is for positive descriptions of what you want. The Exclude field is purpose-built for negatives. Always separate them. Mixing the two can confuse the model and waste credits on generations that ignore your instructions.
