J DILLA

Dilla deliberately avoided quantisation — the MPC's built-in function that aligns notes to a grid. Instead he placed drum hits slightly before or after the beat, creating a "drunk" feel that sounds human rather than mechanical. The kick might land 5–10 milliseconds early, the snare slightly late. This creates a continuous sense of forward motion and rhythmic tension that has been the most studied and imitated approach in contemporary hip hop production.

Dilla's sampling is documented across jazz (Blue Note, Prestige), soul (Motown, Stax), funk (70s independent labels), Brazilian music, classical, rock, and psychedelic records. Donuts contains samples from artists as varied as Frank Zappa, Bobby Fuller Four, George Clinton, and Japanese city pop. His approach was to find a single element — a two-second piano phrase, a drum fill — and build a composition around it.

The WhoSampled database documents many of Dilla's samples — each credit points to a source record worth finding. His Slum Village, Common, D'Angelo, and Erykah Badu productions all contain documented sample sources. The most educational exercise is listening to a Dilla production and the source record back to back — it reveals how dramatically a sample can be transformed through speed change, pitch shift, and chopping.
