Scouse house is a subgenre of UK Hard House music that features an upbeat and energetic sound often described as being "bouncy", often carrying a slightly faster and upbeat pace in comparison to other hard house music and the usage of "pipe"-like bass patterns, consisting of a metallic-sounding synth carrying off-beat 4x4 notes (popularly known as 'donk'). The genre originally developed in early 2000s Liverpool and the other cities in the northwest of England. Scouse house has been influenced somewhat by Happy Hardcore and Bouncy Techno, both often sampled by scouse house producers, MCing techniques from the 90s rave live-set culture, and the pumping house sound of the late 1990s initiated by Dutch producer duo Klubbheads.
