Bass music (also called UK bass, sometimes incorrectly referred to as bassline or post-dubstep) is an umbrella term for club music that emerged in the United Kingdom during the mid-2000s under the influence of diverse genres such as dubstep, UK garage, R&B, wonky, house, and grime. The phrase “bass music” came into use as artists began ambiguously blending the sounds of these defined genres while maintaining an emphasis on percussive, bass-led rhythm.
