Drum & Bass, often shortened to DnB or D&B, is a genre of electronic dance music characterized by its fast tempo, typically ranging from 160 to 180 beats per minute, and complex, syncopated drum patterns known as breakbeats. It's also defined by its heavy basslines, which often feature deep sub-bass frequencies that create a physical sensation on the dance floor. Originating in the UK rave scene of the early 1990s, DnB evolved from breakbeat hardcore and jungle music, incorporating influences from various genres like reggae, dub, funk, and hip-hop. Over time, it has diversified into numerous subgenres, each with its unique sonic characteristics, but all retaining the core elements of fast, intricate rhythms and powerful bass.
