Genre

R&B & soul

Groove-and-voice music where the pocket, the chord voicings and the vocal performance carry everything.

Sound and palette

The first decision is era, because classic soul and contemporary R&B share a lineage but almost no production choices. 60s soul means live band, horn section, tambourine, mono-leaning mix. 70s soul and funk means Rhodes, clavinet, wah guitar, string arrangements and a deep pocket. 90s R&B means swung programmed drums, warm synth pads, layered background vocals and a smooth bass. Contemporary alternative R&B means sparse drums, heavy sub, atmospheric pads, pitched vocal textures and a lot of empty space.

Instrument choice follows directly. Electric piano — Rhodes or Wurlitzer — is the genre's default harmonic instrument across all eras. Add a clean or lightly overdriven guitar playing partial chords, a bass that plays melodically rather than just roots, and either a live kit or a programmed kit with swung sixteenths. Strings and horns are the arrangement upgrades; use one, not both.

  • Keys: Rhodes, Wurlitzer, Hammond organ, warm analogue pad, clavinet for funk.
  • Bass: melodic electric bass, muted fingerstyle, 808 sub for modern R&B.
  • Guitar: clean partial chords, wah rhythm, muted single-note lines.
  • Horns and strings: punchy horn stabs, or a silky string pad — pick one.
  • Percussion beyond the kit: tambourine, shaker, rim clicks, finger snaps.

Rhythm, tempo and harmony

R&B tempos run 60–100 BPM most of the time, with neo-soul often near 72–88 and contemporary R&B frequently halftime at 130–150 written. The defining rhythmic property is not tempo but feel: swung sixteenths, laid-back behind-the-beat drums, tight pocket with a lazy snare. Saying the drums sit slightly behind the beat is one of the highest-value instructions in this genre.

Harmony is richer than in pop and worth naming. Extended chords with ninths and elevenths, minor seventh vamp, chromatic passing chords and gospel-flavoured voicings push results away from generic triad pop. A two-chord vamp with rich voicings is more idiomatic than a busy four-chord loop.

Vocal behaviours

This is the most vocal-defined genre in the guide, so spend prompt words there. Specify tone (warm alto, silky tenor, gritty gospel-trained voice), technique (melisma and runs at phrase ends, falsetto lift in the chorus, breathy close delivery) and stacking (thick layered background harmonies, call-and-response ad-libs, doubled octave on the hook).

Restraint is also a valid instruction. Contemporary alternative R&B often wants the opposite of virtuosity: understated, almost spoken delivery, minimal runs. Say which side you are on, because leaving it open tends to produce a middling performance with a few reflexive runs.

Background vocals are the genre's signature texture. Thick stacked background harmonies under the lead, ad-libs answering each line transforms a flat result into something idiomatic.

Production character and pitfalls

Production cues that work: warm analogue, tape saturation for classic material; smooth polished 90s mix, wide reverb on the vocal for that era; sparse modern mix, deep sub, lots of space for contemporary. Compression style matters — say gentle, breathing compression if you want the live-band feel, or tight controlled drums for the programmed sound.

The frequent failure modes: era-mixing (live horn section plus 808 sub), over-filling the arrangement so the pocket disappears, forgetting the swing instruction and getting a stiff straight groove, and asking for both virtuosic runs and understated delivery in the same line.

  • Name the era and stay inside its palette.
  • State the feel — swung sixteenths, behind the beat.
  • Ask for background stacks explicitly.
  • Prefer a two-chord vamp with rich voicings over a busy loop.
  • Leave space; a crowded R&B mix kills the groove.

FAQ

How do I get that laid-back R&B pocket?
Say it directly: drums laid back behind the beat, swung sixteenths. Without a feel instruction the model usually returns a stiff, quantised groove.
How do I get rich chords instead of plain triads?
Ask for extended harmony — ninths, elevenths, minor seventh vamp, gospel voicings — and consider requesting a two-chord vamp so the voicings have room to be heard.
What's the difference between soul and R&B in a prompt?
Mostly era and instrumentation. Soul implies a live band with horns and organ; R&B implies programmed or hybrid drums, electric piano, synth pads and layered vocal production.
How do I stop the model adding runs everywhere?
Specify restraint: understated delivery, minimal runs, no melisma. R&B prompts default to virtuosic phrasing unless you say otherwise.
