Dubstep is a genre of electronic music characterized by pulsating bass lines, aggressive break beats, and schizophrenic synthesizers and samples. The genre extensively uses tuplets (non standard divisions of the song's meter), syncopation, and the infamous "wobble" bass. The genre emerged from a cross between house music and drum & bass in the UK during the late 90's and has grown in popularity in the club and rave scenes since. A few notable dubstep artists would be Skrillex, 12th Planet, and Bassnectar. Elements of dubstep music are commonly found in modern dance, hip-hop, and pop music.
