Bassline is a type of music related to UK garage that originated from speed garage, and shares characteristics with fellow subgenres dubstep and grime for their emphasis on bass. The style originated in Sheffield around 2002. Like dubstep and grime, bassline generally places a strong emphasis on bass, with intricate basslines (often multiple and interweaving) being characteristic of the genre. Bassline tracks use a four-to-the-floor beat. The music is often purely instrumental, but vocal techniques common in other styles of garage can also be present, such as female R&B vocals sped up to match the faster tempo, and also samples of vocals from grime tracks. Most songs are around 135 to 142 bpm, faster than most UK garage and around the same tempo as most grime and dubstep. .
