Drum and Bass (also called jungle) is an energetic branch of electronic Dance music and has its musical roots in the hardcore rave movement in the United Kingdom in the early 90s. Over its lifespan, the music has drawn in influences from such diverse fields as Jazz, Ragga, Hip Hop and R&B. The music is characterised by rapid breakbeats running at BPMs around the 170 mark. Whilst the music largely lives and was born on the dancefloor it has diversified into many different categories, some of which concentrate rather more heavily on the listener's sensibilities than their feet. As a result of the music's constant growth and mutation, Drum and Bass has been split into numerous subgenres and types. These include: Artcore, Techstep, Hardstep, Jump-Up, Liquid Funk, Ragga Jungle, Jazzstep and so on.
