Slightly detune the piano to mimic the pitch variations found in old vinyl samples. 3. Drum Programming

Use an upright bass (common in jazz-sampled hip hop) or a subby synth like a Moog .

For a rap-ready instrumental, ensure there is space for the artist: 4-8 bars (piano only or with noise).

Place the kick on the first beat, with a secondary "ghost" kick or a shifted second hit to create a syncopated, swinging rhythm.

16 bars (drums, bass, and main piano). Consider "airing out" the verse by pulling back some musical elements so the rapper has room.

Keep hi-hats simple. A secret technique is to shift every other hi-hat slightly off-grid to create a "dragging" effect.
