Jungle (sometimes oldschool jungle), is a genre of electronic music that developed in England in the early 1990s as part of rave music scenes. The style is characterized by fast tempos (150 to 170 bpm), relatively slow and lyrical reggae-derived basslines, breakbeats, and other heavily syncopated percussive loops, samples and synthesized effects make up the easily recognizable form of jungle. Long pitch-shifted snare rolls are common in oldschool jungle. The terms "jungle" and "drum and bass" are often used interchangeably, although whether the two genres are actually distinct is an ongoing topic of debate. For those individuals who consider the two genres as separate entities, drum and bass is usually considered to have departed from jungle in the mid to late 1990s.
