Quick answer: R&B usually sits between about 65 and 95 BPM, slower for slow jams and quicker for uptempo, pop-leaning songs. Ask for a laid-back groove, warm seventh and ninth chords on keys or guitar, deep bass or soft 808s, and a smooth, breathy or soulful vocal with harmonies or ad-libs. Romantic or reflective lyrics with specific moments suit it best.

R&B with AI: a slow groove and a voice up close
R&B lives in the space between the beats. A relaxed groove, warm extended chords and a vocal that feels close to your ear matter more than any single instrument. Describe the feel and the voice, and keep the arrangement uncluttered.
- Tempo
- Slow jams 60 to 75, neo-soul 70 to 95, uptempo up to about 110
- Feel
- Relaxed, often swung; snare or clap on 2 and 4
- Harmony
- Major 7th, minor 9th and other extended chords
- Core sounds
- Rhodes, clean guitar, deep bass or soft 808s, crisp hi-hats
- Vocals
- Smooth lead, stacked harmonies, ad-libs and runs
Defining traits
What makes it R&B
- 01
The vocal is the lead instrument
R&B arrangements step aside for the singer. Describe the voice in detail (breathy, silky, soulful, close-mic'd) and mention harmonies or ad-libs if you want them in the chorus.
- 02
Chords with a soft edge
Extended chords like major sevenths and minor ninths give R&B its warmth. "Warm Rhodes chords" or "jazzy guitar chords" in a prompt gets you there without naming theory.
- 03
Space in the groove
A slow, unhurried beat with room between hits is what makes R&B feel sensual rather than busy. Ask for a minimal or sparse beat and let the bass carry the movement.

Prompting
What to write, what to skip
Works
- Spend most of the prompt on the voice: texture, closeness, harmonies.
- Ask for warm or jazzy chords instead of naming every instrument.
- Keep the beat sparse so the vocal has room.
- Write lyrics around one specific moment, not love in general.
Doesn't
- A busy arrangement with leads competing with the vocal.
- Fast tempos without saying "uptempo R&B".
- Generic lyrics made only of "baby" and "tonight".
- Naming a famous singer instead of describing the vocal.
