Every prompt below goes in Udio's Prompt box — the description that sets the sound world: subgenre, mood, vocal delivery, instruments and tempo. Paste the whole line, generate, then tweak. Prompts that include a Lyrics: block are showing you what to drop into the separate Lyrics box — section tags in square brackets and (ad-libs) inside the lines. Type / in the Lyrics box to insert guidance tags, or flip on Auto lyrics if you only want the beat.
One rule throughout: describe a style, never name a real artist. Udio blocks or deflects artist names, so "aggressive drill flow" or "laid-back 90s boom-bap delivery" gets you the sound; a real name usually gets you nothing. For more building blocks, keep the Udio prompt cheat sheet handy, see the full best Udio prompts roundup, or learn the structure in how to prompt Udio for songs.
Trap bangers (1-5)
Trap runs on deep 808 sub-bass, fast rolling hi-hats and a rattling snare, written at 130-170 BPM with a half-time feel so it hits slow and hard. Put the subgenre and 808s first — Udio weights the earliest words most, and a high Prompt Strength keeps them locked.
1. Dark trap banger
dark trap, menacing and confident, aggressive rapped male vocal with ad-libs, deep 808 sub-bass, fast rolling hi-hats, rattling snare, ominous dark synth lead, key of F# minor, 145 BPM half-time feel, 48kHz stereo, hard-hitting mixBest for: a hard, radio-ready trap instrumental with room for a confident verse.
2. Nighttime trap anthem
moody nighttime trap, atmospheric and cold, smooth confident rapped male vocal, booming 808s, skittering triplet hi-hats, crisp claps, reverbed bell melody, key of C minor, 140 BPM half-time, 48kHz stereo, spacious hard-hitting mixWhy it works: "moody" and "atmospheric" up front steer Udio away from generic hype into a distinct late-night vibe.
3. Aggressive trap with lyrics
hard aggressive trap, high-octane and defiant, punchy rapped male vocal with heavy ad-libs, deep distorted 808s, fast rolling hi-hats, rattling snare, dark brass stabs, 150 BPM half-time feel, 48kHz stereo, hard-hitting mix
Lyrics:
[Intro]
(yeah) (let's go)
[Verse]
Came from the bottom now I'm running up the count (up)
Every move calculated, ain't no doubt (no doubt)
[Hook]
Top floor, top floor, watch me climb (climb)
Been down before, now I'm up on time (yeah)Best for: a full-energy verse-and-hook trap cut where the parenthetical ad-libs push the momentum.
4. Spacey ambient trap
ambient trap, dreamy and floating, laid-back melodic rapped male vocal, warm 808 sub-bass, soft rolling hi-hats, airy pad chords, distant plucked synth, key of D minor, wide reverb, 132 BPM half-time, 48kHz stereo mixWhy it works: softer 808s and pads keep the low end big without the beat feeling combative.
5. Hard-hitting trap posse cut
energetic trap, driving and triumphant, two trading rapped male voices with ad-libs, thunderous 808s, fast rolling hi-hats, big snare rolls, bright horn sample, 148 BPM half-time feel, 48kHz stereo, festival-loud hard-hitting mixBest for: a group-anthem feel with call-and-response energy between two voices. If one voice lands weak, swap that bar with Inpainting.
Drill (6-9)
Drill is defined by a sliding 808 bass, a syncopated snare and dark piano at 140-145 BPM. The gliding bass is the signature — call it out explicitly or you'll get plain trap.
6. UK drill street track
UK drill, dark and menacing, gritty rapped male flow, sliding 808 bass, syncopated snare, dark minor piano, sparse hi-hats, key of G minor, 143 BPM, 48kHz stereo, cold cinematic hard-hitting mixBest for: an authentic drill instrumental with the classic sliding-bass glide.
7. Sliding-808 drill with hook
drill, aggressive and tense, confident rapped male vocal with ad-libs, deep sliding 808 bass, syncopated snare, eerie flute melody, dark piano, 144 BPM, 48kHz stereo, hard-hitting mix
Lyrics:
[Intro]
(brr) (yeah)
[Verse]
Step out the whip and the block go quiet (shh)
Move in silence, never start a riot (nah)
[Hook]
On the road, on the road, we don't fold (never)
Same crew from the days when it was cold (facts)Why it works: the eerie flute over a sliding 808 is a drill staple, and the sparse ad-libs sit right in the pocket.
8. Dark piano drill
drill, brooding and cold, low intense rapped male vocal, sliding 808 bass, crisp syncopated snare, haunting grand piano, subtle string pad, key of E minor, 142 BPM, 48kHz stereo, spacious dark mixBest for: a cinematic drill beat led by the piano rather than a synth melody.
9. Brooklyn drill energy
Brooklyn drill, hard and urgent, punchy rapped male vocal with ad-libs, hard sliding 808 bass, snappy syncopated snare, dark synth bells, gritty texture, 145 BPM, 48kHz stereo, loud aggressive hard-hitting mixWhy it works: "urgent" and "hard" beat vague words like "energetic" that the model reads as weak.
Boom bap & lo-fi rap (10-14)
Boom bap swaps 808s for a sampled jazz or soul loop, punchy dusty drums and a vinyl scratch, at a laid-back 85-100 BPM. Ask for a "90s boom-bap flow" for that golden-era delivery, or drop the drums out for lo-fi.
10. Classic boom bap
90s boom bap, nostalgic and confident, laid-back rapped male flow, sampled jazz piano loop, punchy dusty drums, warm upright bass, vinyl scratch, crackle texture, 92 BPM, 48kHz stereo, warm tape mixBest for: a timeless East Coast head-nodder with real golden-era warmth.

Lyrics:
[Intro]
(uh) (yeah, check it)
[Verse]
Pen to the pad and the ink never dries (never)
City on my back like the weight of the skies (word)
[Hook]
We do it for the culture, keep it pure (pure)
Timeless like the records that endure (uh)Why it works: a sampled sax loop plus walking upright bass reads as authentic 90s jazz-rap to Udio.
12. Dusty soul-sample loop
boom bap, warm and soulful, gritty confident rapped male vocal, chopped vintage soul vocal sample, dusty punchy drums, deep round bass, vinyl crackle, key of A minor, 88 BPM, 48kHz stereo, tape-warm mixBest for: the chopped-soul, sample-flip sound with a warm analog character.
13. Golden-era battle rap
boom bap, hard and competitive, sharp punchy rapped male battle-rap flow, gritty sampled horn loop, hard-hitting dusty drums, thick bassline, vinyl scratch cuts, 95 BPM, 48kHz stereo, raw mixWhy it works: "battle-rap flow" plus scratch cuts gives it that raw, competitive cypher edge.
14. Lo-fi study rap
lo-fi hip-hop, mellow and cool, relaxed spoken-rapped male vocal, jazzy Rhodes loop, soft dusty drums, smooth upright bass, heavy vinyl crackle, tape hiss, key of F major, 84 BPM, 48kHz stereo, warm intimate mixBest for: a chilled lo-fi cut for reflective or study-playlist verses.
Melodic & emo rap (15-18)
Melodic rap blurs singing and rapping over lush, spacey production. Ask for melodic auto-tuned rap or a "breathy melodic rap" and give it a real emotional mood — Udio handles the music theory to keep the topline in key.
15. Melodic auto-tuned rap
melodic trap, emotional and hazy, melodic auto-tuned male rap-singing, warm 808 sub-bass, soft rolling hi-hats, dreamy guitar arpeggio, lush reverb pads, key of B minor, 138 BPM half-time, 48kHz stereo, polished mixBest for: the sung-rap, auto-tuned sound with a catchy melodic hook.

Lyrics:
[Verse]
Been up all night with the thoughts on repeat (yeah)
Chasing a feeling I can't quite reach (oh)
[Hook]
Tell me if it's real, real, real (real)
'Cause I've been running on how it feels (ooh)Why it works: "breathy" and "bittersweet" plus a distorted guitar push the vocal toward emo-rap emotion instead of hard rapping.
17. Cloud rap dreamscape
cloud rap, ethereal and floating, hazy auto-tuned male rap-singing, soft distorted 808s, muffled hi-hats, shimmering synth pads, distant chimes, washed-out reverb, key of A minor, 130 BPM half-time, 48kHz stereo mixBest for: a dreamy, washed-out atmosphere with vocals melting into the beat.
18. Sung-rap crossover
melodic rap pop, uplifting and catchy, melodic male rap-singing with bright topline, punchy 808s, crisp hi-hats, bright plucked synth, layered harmonies, key of G major, 140 BPM half-time, 48kHz stereo, radio-polished mixWhy it works: "bright topline" and "layered harmonies" tilt it toward a crossover, playlist-friendly hook.
Storytelling & conscious (19-22)
For narrative and conscious rap, keep the beat warm and out of the way, and give the vocal a clear point of view. Soulful, jazzy backdrops let the words lead, and a higher Lyrics Strength keeps the flow tight.
19. Storytelling street narrative
storytelling hip-hop, cinematic and vivid, clear narrative rapped male flow, soulful sampled string loop, steady boom-bap drums, deep warm bass, subtle vinyl crackle, key of D minor, 93 BPM, 48kHz stereo, warm mixBest for: a detailed story rap where every line needs to land clearly.

Read between the lines of what they tell you is free (uh)
[Hook]
Keep your eyes open, keep your mind clear (clear)
Truth in the noise if you learn how to hear (yeah)Why it works: "measured articulate" pacing gives the message room to breathe over a soulful bed.

22. Spoken-word intro into rap
conscious hip-hop, poetic and grounded, spoken-word intro into steady rapped male vocal, mellow jazz piano loop, brushed dusty drums, warm double bass, faint vinyl crackle, 90 BPM, 48kHz stereo, warm mix
Lyrics:
[Intro]
(spoken) They asked me where I'm going — I said listen, first hear where I've been

Turned the pain to a purpose, ain't nobody the same (yeah)
[Hook]
This is more than the music, it's a life (life)
Everything I lived in it is rightWhy it works: the (spoken) cue in the [Intro] sets a poetic tone before the rapped verse kicks in.
Hype & club (23-26)
Hype and club tracks need big, driving energy and a chantable hook. Reach for words like triumphant, adrenaline-fueled and high-octane instead of a flat "energetic".
23. Hype workout anthem

Started with nothing but a plan and a grind (grind)
Every closed door was a lesson in disguise (yeah)
[Hook]
Rise up, rise up, we don't quit (rise up)
Every setback just adds to the win (let's go)Why it works: orchestral strings plus an anthemic choir turn a chant hook into a genuine anthem.
25. Club banger for the floor
club rap, high-octane and explosive, hard-shouting rapped male vocal with crowd ad-libs, booming 808s, driving four-on-the-floor kick, fast hi-hats, huge synth stabs, 128 BPM, 48kHz stereo, club-loud hard-hitting mixBest for: a peak-time floor filler, DJ edits and big-room intros.

When you Extend any of these into a full song, re-paste the key Prompt tags each time — subgenre, 808 character and BPM — so the beat and voice don't drift, and work in the Sessions editor for anything long. If a single bar or ad-lib comes out wrong, use Inpainting to regenerate just that region instead of re-rolling the whole take. For the tag reference, revisit the Udio prompt cheat sheet, adapt a skeleton from the Udio prompt templates, and for the full workflow see the best Udio prompts roundup.
Frequently Asked Questions
How do I get heavy 808 bass in Udio?
Put the bass early in the Prompt box and be specific: deep 808 sub-bass, booming 808s, or sliding 808 bass for drill. Pair it with a low BPM and a half-time feel so the low end has room to hit. Adding "48kHz stereo, hard-hitting mix" helps, and raising Prompt Strength keeps Udio locked to your low-end description.
What BPM should trap and drill be in Udio?
Trap sits at 130-170 BPM but is written with a half-time feel, so the beat sounds slow while the hi-hats roll fast. Drill is faster and more specific at 140-145 BPM with a sliding 808 and syncopated snare. Boom bap is slower at 85-100 BPM. State the BPM in the Prompt box and Udio, which handles music theory, will lock the tempo.
Why won't Udio rap in a specific artist's voice?
Udio blocks or deflects real artist names, so naming a rapper rarely works and can water down the result. Describe the style instead: aggressive drill flow, laid-back 90s boom-bap delivery, melodic auto-tuned rap, or breathy melodic rap. Describing the flow, tone and era gives you the sound without the blocked name.
How do I write rap lyrics in Udio's Lyrics box?
In the Lyrics box, put section tags on their own line in square brackets: [Intro], [Verse], [Hook], [Bridge], [Outro]. Type / to insert guidance tags, and write ad-libs and backing vocals inside the lines in parentheses, like (yeah). Keep the sound world in the Prompt box, or switch on Auto lyrics if you only want to shape the beat.
Trap vs boom bap — what tags change in Udio?
Trap uses deep 808 sub-bass, fast rolling hi-hats, rattling snare and dark synth leads around 130-170 BPM with a half-time feel. Boom bap swaps those for a sampled jazz loop, punchy dusty drums, vinyl scratch and a laid-back flow at 85-100 BPM. The drums and bass character change most: modern 808s and hats versus sampled, dusty, sample-based drums.
What does Inpainting do for a rap track?
Inpainting lets you select a short region, about two seconds, and regenerate only that part while the rest of the track stays fixed. Use it to swap a weak bar, fix a garbled ad-lib or clean up an off-beat snare fill without re-rolling the whole song. It is the fastest way to salvage a take that is 90 percent right but has one bad moment.
How do I keep the beat consistent when I Extend a rap song in Udio?
Extend adds about 30 seconds and stays closer to your original than a fresh generation, but re-paste the key Prompt tags — subgenre, 808 character and BPM — on each extension so the beat and voice don't drift. For long structured songs, work in the Sessions editor and lean on the Prompt Strength and Lyrics Strength sliders to hold the sound in place.
Should I use the Instrumental toggle or Stems?
Flip the Instrumental toggle when you want a beat with no vocals — handy for making a rap instrumental to rap over yourself. Use Stems after generating a full track to export separated parts, so you can remix the 808s, drums or vocal on their own. Both pair well with the 48kHz stereo output for a clean, hard-hitting mix.
