Bass music (also called UK bass or post-dubstep) is an umbrella term that refers broadly to electronic dance music that emerged in the mid-'00s under the influence of dubstep, UK garage, 2-step, drum and bass, wonky, house and other electronic styles centered in the United Kingdom. The phrase "bass music" came into use as artists began ambiguously blending the sounds of these defined genres while maintaining an emphasis on bass and rhythm.
