Dancehall riddim — the digital Jamaican sound that began in 1985 when Wayne Smith and Noel Davey built "Under Mi Sleng Teng" from a Casio keyboard preset, finished in King Jammy's studio, and that runs through Steely & Clevie and on to Lenky's Diwali riddim (Sean Paul, Wayne Wonder) in 2002. A riddim is the backing track; dozens of deejays voice the same one.
How it sits: a plain kick on 1 and 3 and snare on 2 and 4 hold the floor, and a handclap cuts across them on the 3-3-2 — beat 1, the "and" of 2, beat 4 — the push that makes the Diwali family bounce. Sixteenth hats keep it moving; a pickup kick on the last sixteenth throws it back to the top. The synth bass is a one-chord minor ostinato in the Sleng Teng mould: root, repeated root, then a climb up to the fifth, answered differently in bar 2.
Listen for the clap and snare never quite agreeing. Practice: clap the 3-3-2 while stepping on 1 and 3. Compare reggaeton-dembow, its Panamanian-Puerto Rican descendant.
