Bassline (music genre)
Bassline (sometimes referred to as bassline house or 4x4 or niche) is a genre of electronic dance music that originated in South Yorkshire in the early 2000s. Stylistically it comprises a four-to-the-floor beat with a tempo of around 135–142 beats per minute and a heavy bass, similar to speed garage, with chopped up R&B and Pop vocal samples and a pop music aesthetic.
