# R&B AI music prompts

Contemporary R&B is slow, groove-led music at 60 to 100 BPM (beats per minute), built for the voice. Laid-back drums with crisp snaps or rimshots sit on a deep 808 sub bass (a long, low bass note named after a drum machine), under warm electric piano or pad chords with extended voicings such as ninths and elevenths. The lead vocal is silky and layered with harmonies and ad-libs.

A prompt should name the tempo, drum feel, chord instrument, bass, vocal delivery and a smooth, spacious mix.

## At a glance

| Tempo | 60 to 100, most often 65 to 90 BPM (Lyro default 84) |
|---|---|
| Keys | minor keys with extended chords (sevenths, ninths, elevenths), often E minor or F minor |
| Feel | laid-back and swung, snare or snap on two and four, hi-hats often in triplets or rolls |
| Length | songs run 2.5 to 4 minutes; for social clips use the hook or a vocal run, 15 to 30 seconds |
| Instruments | 808 sub bass, electric piano, lush pads, finger snaps, rimshots, programmed hi-hats, clean electric guitar, soft synth keys, layered vocal harmonies |
| Signature sounds | a close, breathy lead with melisma, stacked harmonies and ad-libs, extended electric piano chords, a deep 808 or sub bass, and slow swung drums with snaps |
| Typical form | usually verse, pre-chorus and chorus with subtle changes between them, a bridge that strips back to keys and voice, and a last chorus full of ad-libs |
| On Lyro | Song on Lyro High. R&B puts a close, detailed vocal at the centre, so the words and the phrasing have to come through, and sung lyrics go to Lyro High by default. With English lyrics, Lyro Extra is worth a try for the more expressive vocals its provider describes. If you sing yourself, record the vocal and let Lyro write the beat around it. That runs in Lyro’s studio tools, on the Creator plan. 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 it differs from its neighbours

- [Hip-hop](https://lyromusic.com/prompts/hip-hop): a similar tempo at 80 to 100 BPM, but rapped over a sampled, swung drum break
- [Trap](https://lyromusic.com/prompts/trap): shares the 808 and the hi-hat rolls at a half-time feel of 65 to 80 BPM, with a darker and harder sound
- [Funk and soul](https://lyromusic.com/prompts/funk-and-soul): the live-band ancestor, with horns, a syncopated rhythm section and gospel-rooted singing

## How to prompt it

### Arrangement

R&B songs follow verse, pre-chorus and chorus, but the changes are subtle. Verses are sparse, with drums, bass and a few chords under the lead. The chorus adds harmonies and thicker pads instead of getting louder. A bridge often strips back to keys and voice, sometimes with a change of key or feel, before a last chorus full of ad-libs.

### Vocals

The vocal is the main instrument in R&B. Expect a close, breathy lead, melisma (several notes sung on one syllable), falsetto, stacked harmonies and ad-libs that answer the main line. Ask for the delivery, the layering and where the ad-libs go. Keep the lead upfront and dry enough to feel intimate.

### Tips

- Name the chords as well as the instrument, for example "electric piano with minor ninth chords", to get the rich harmony.
- Ask for a laid-back or behind-the-beat drum feel, since stiff timing removes the groove.
- Describe the vocal layers, such as breathy lead, stacked harmonies and ad-libs, because the vocal arrangement defines the genre.
- Choose the era, since a 1990s slow jam, 2000s uptempo, neo-soul and modern trap-soul each have a distinct drum and keyboard sound.
- Use mix words like smooth, warm, spacious and intimate.

### Common mistakes

- Asking for high energy turns the track into dance-pop, because the genre works through restraint.
- Skipping the bass description often gives a thin low end, when a deep 808 or a warm bass guitar should anchor the song.
- Requesting a loud belted vocal throughout removes the dynamics, and the intimate verses disappear.

## Questions

### What BPM is r&b?

R&B usually sits at 60 to 100, most often 65 to 90 BPM, with laid-back and swung, snare or snap on two and four, hi-hats often in triplets or rolls. Lyro Music’s default for r&b is 84 BPM, and you can type any tempo into your prompt.

### What key is r&b usually in?

Minor keys with extended chords (sevenths, ninths, elevenths), often E minor or F minor. 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 r&b track sound right?

The sounds that identify it are a close, breathy lead with melisma, stacked harmonies and ad-libs, extended electric piano chords, a deep 808 or sub bass, and slow swung drums with snaps. In a prompt, name three or four of these: 808 sub bass, electric piano, lush pads, finger snaps, rimshots, programmed hi-hats.

### How do I write a r&b 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: “Contemporary R&B, 84 BPM, slow swung drums with crisp snaps and a deep 808 sub, soft hi-hat triplets. Warm electric piano and lush pad chords with extended voicings, clean guitar licks between lines. Silky intimate female lead vocal with breathy ad-libs and layered harmonies in the chorus. Late-night, longing mood, smooth spacious mix with the vocal close and upfront.” Name the chords as well as the instrument, for example "electric piano with minor ninth chords", to get the rich harmony.

### What should I avoid in a r&b prompt?

Asking for high energy turns the track into dance-pop, because the genre works through restraint. Skipping the bass description often gives a thin low end, when a deep 808 or a warm bass guitar should anchor the song.

### How is r&b different from hip-hop?

Hip-hop is a similar tempo at 80 to 100 BPM, but rapped over a sampled, swung drum break.

### How long should a r&b track be?

Songs run 2.5 to 4 minutes; for social clips use the hook or a vocal run, 15 to 30 seconds. Lyro Music makes tracks from 30 seconds to 3 minutes.

### Which Lyro Music mode suits r&b?

Song, which runs on Lyro High. R&B puts a close, detailed vocal at the centre, so the words and the phrasing have to come through, and sung lyrics go to Lyro High by default.
