Drum and bass (commonly abbreviated to d&b, DnB, dnb, d'n'b, drum n bass and drum & bass) is a type of electronic dance music also known as jungle. Emerging in the early 1990s, the genre is characterised by fast tempo broken beat drums (generally between 160–180 beats per minute) with heavy, often intricate basslines. Today, drum and bass is still considered an underground musical style, but its currents of influence run throughout popular music and culture.
