Drum 'n' Bass is a genre of electronic music which was created in the 1990s.
Drum 'n' bass music consists of the following musical elements: Fast-paced tempo (Usually 160-180 beats per minute (BPM)); complex, breakbeat-based drum lines; and heavy emphasis on basslines and sub-basslines
However, beyond these musical traits, drum 'n' bass is a highly varied musical genre overall. It contains multiple subgenres, each which have their own musical traits and influences. Two prominent examples of drum 'n' bass subgenres are Liquid Drum 'n' Bass (also known as Liquid Funk) and Dance Drum 'n' Bass. It has musical influences ranging from hip-hop and ragga to breakbeat music and industrial techno music. The instrumentation typically consists of a drum line, a bass and sub-bass line, and a synth line; however, many other instruments such as vocals and even jazz instruments are also used. How these instruments are used is based on the song itself, as the instrumentation of a drum 'n' bass song can vary widely from song to song. Many drum 'n' bass songs use samples from other media as part of their songs.
Drum 'n' Bass started as an offshoot of the British rave music scene in the 1990s. Rave music had many of drum 'n' bass's musical traits such as complicated breakbeats and use of sampling; however, rave music was typically slower-paced, usually featuring a tempo of 130-140 BPM. Over time, DJs started to produce faster rave music, which led to the development of jungle music, the first form of drum 'n' bass. By the mid-90s, jungle music became mainstream in Britan; and it evolved into modern drum 'n' bass music. Although drum 'n' bass is not as mainstream now as it was in the mid-90s, it is still constantly featured in mainstream media, from media soundtracks to influences in currently popular genres such as dubstep.
