Drum And Bass

Also written as drum 'n' bass and commonly abbreviated to D&B, D+B or DnB, drum and bass is a type of electronic music characterized by fast breakbeats (typically between 160–180 beats per minute), with heavy bass and sub-bass lines. The sounds of drum and bass are extremely varied due to the range of influences behind the music. Of equal importance is the TR-808 kick drum, an artificially pitch-downed or elongated bass drum sound sampled from Roland's classic TR-808 drum machine, and a sound which has been subject to an enormous amount of experimentation over the years. The complex syncopation of the drum tracks' breakbeat, is another facet of production on which producers can spend a very large amount of time.
