New Jack Swing, or "swingbeat", is a hybri style popular from the late-1980s into the mid-1990s, which fuses the rhythms, samples and production techniques of hip-hop with the urban contemporary sound of R&B. The new jack swing style developed as many previous R&B styles did, by combining elements of older styles with newer trends. It uses mellifluously soulful solo or harmonizing vocals sung over rhythms and "street" beats derived from urban musical influences. The sound of New Jack Swing comes from the hip hop "swing" beats created by drum machine, and hardware samplers, which was popular during the golden age of hip hop, with contemporary R&B style singing.
