Dembow comes from Jamaican dancehall, taking its name and rhythm from Shabba Ranks' 1990 track 'Dem Bow'. The pattern was adopted in Panama and Puerto Rico during the 1990s, where it became the defining beat of early reggaeton and Spanish-language dancehall. Old school versions keep the sound stripped back, with a hard kick, snare and sparse percussion instead of modern polished production. That raw, recognisable groove later spread through soundboards, DJ sets and social video, and creators still use it to signal classic reggaeton, Latin party energy and dance culture.
