Lo-fi AI music prompts
Lo-fi hip-hop is slow, instrumental beat music at 60 to 90 BPM (beats per minute), made to sound worn and warm. A soft, dusty drum loop with a lazy swing sits under mellow jazz chords on electric piano, piano or guitar, with a simple bass and deliberate imperfections: vinyl crackle, tape wobble and rolled-off highs. It is background music by design.
A prompt should name the tempo, the drum feel, the chord instrument, the texture (crackle, tape, rain) and a soft, muffled mix.
At a glance
| Tempo | 60 to 90, most often 70 to 85 BPM (Lyro default 78) |
|---|---|
| Keys | minor or major with seventh and ninth chords, often D minor or C major |
| Feel | swung, slightly late drums with a soft kick and a muffled snare or rimshot |
| Length | tracks are short loops of 2 to 3 minutes; for social clips or study streams any 20 to 30 second loop works |
| Instruments | dusty drum loop, electric piano, felt piano, muted guitar, soft sub bass, upright bass, mellow saxophone, vinyl crackle, tape wobble, rain ambience |
| Signature sounds | soft swung drums that land slightly late, mellow electric piano or guitar chords with sevenths and ninths, vinyl crackle, tape wobble and rolled-off highs |
| Typical form | usually a loop: a few seconds of crackle or filtered chords, then the drums, and a four or eight bar progression that repeats with small changes before a fade or a tape-stop ending |
| On Lyro | Instrumental on Lyro High or Lyro Extra. Lo-fi is almost always instrumental, and Lyro High is the default for instrumentals. For a loop that has to sit at a set tempo under a video or a stream, give the BPM; the models treat it as guidance rather than an exact lock, so check the render with the free BPM and key finder at /tools/bpm-key-finder.
We have not run a listening test in this genre. The suggestion follows Lyro’s general routing rule, which comes from one small blind test in Turkish (one rater, seven briefs, 21 Sep 2026), where the model behind Lyro High, the default, had the highest scores. Lyro Extra was added after that test. How we test |

How to prompt it
Arrangement
Lo-fi tracks are loops with small changes. A few seconds of crackle or a filtered version of the chords opens the track, the drums enter, and the same four or eight bar progression repeats. Variation comes from dropping the drums for a bar, adding a counter-melody or filtering the whole mix. Tracks fade out or stop like a tape being switched off.
Vocals
Lo-fi is almost always instrumental. When a voice appears it is a texture: a hummed line, a short spoken phrase or a chopped, filtered sample sitting low in the mix. Ask for it to be soft, filtered and occasional. For none, which is the usual choice, write: instrumental only, no vocals.
Tips
- Ask for imperfections by name, such as vinyl crackle, tape wobble, soft saturation and rolled-off highs, because they are the sound.
- Describe the drums as soft, dusty and laid-back with a lazy swing, never punchy.
- Name the chord instrument and ask for jazzy seventh or ninth chords to get the mellow harmony.
- Add one ambient layer, such as rain, a cafe murmur or night crickets, for a sense of place.
- Keep the prompt instrumental unless you want a short spoken or hummed texture.
Common mistakes
- Asking for a clean, bright or punchy mix removes the character, and the result is ordinary instrumental hip-hop.
- Going above 90 BPM makes the beat feel busy, which defeats music meant to sit behind work or study.
- Adding a full lead vocal pulls attention to the foreground, the opposite of what the genre is for.

Questions
What BPM is lo-fi?
Lo-fi usually sits at 60 to 90, most often 70 to 85 BPM, with swung, slightly late drums with a soft kick and a muffled snare or rimshot. Lyro Music’s default for lo-fi is 78 BPM, and you can type any tempo into your prompt.
What key is lo-fi usually in?
Minor or major with seventh and ninth chords, often D minor or C major. The key sets the mood more than it sets the genre, so treat it as a starting point and change it if the song needs to feel brighter or darker.
Which instruments make a lo-fi track sound right?
The sounds that identify it are soft swung drums that land slightly late, mellow electric piano or guitar chords with sevenths and ninths, vinyl crackle, tape wobble and rolled-off highs. In a prompt, name three or four of these: dusty drum loop, electric piano, felt piano, muted guitar, soft sub bass, upright bass.
How do I write a lo-fi prompt for Suno, Udio or Lyro Music?
Start with the genre and tempo, then the drums, bass, lead sound, voice and mix, in that order. For example: “Lo-fi hip-hop, 78 BPM, soft dusty drum loop with laid-back swing, muffled snare, warm mellow electric piano chords with seventh voicings, gentle muted guitar, soft sub bass. Vinyl crackle and tape wobble across the whole track. Cosy, nostalgic late-night study atmosphere, smooth rolled-off highs, quiet and unhurried. Instrumental only, no vocals.” Ask for imperfections by name, such as vinyl crackle, tape wobble, soft saturation and rolled-off highs, because they are the sound.
What should I avoid in a lo-fi prompt?
Asking for a clean, bright or punchy mix removes the character, and the result is ordinary instrumental hip-hop. Going above 90 BPM makes the beat feel busy, which defeats music meant to sit behind work or study.
How is lo-fi different from hip-hop?
Hip-hop is the same swung drums and samples at 80 to 100 BPM, with a rapped vocal on top.
How long should a lo-fi track be?
Tracks are short loops of 2 to 3 minutes; for social clips or study streams any 20 to 30 second loop works. Lyro Music makes tracks from 30 seconds to 3 minutes.
Which Lyro Music mode suits lo-fi?
Instrumental, which runs on Lyro High or Lyro Extra. Lo-fi is almost always instrumental, and Lyro High is the default for instrumentals.
