Dub is an electronic musical style that grew out of reggae in the late 1960s and early 1970s. It is commonly considered a subgenre of reggae, though it has developed to extend beyond that style. Generally, dub consists of remixes of existing recordings created by significantly manipulating the original, usually through the removal of vocal parts, the application of studio effects such as echo and reverb, emphasis of the rhythm section (the stripped-down drum-and-bass track is sometimes referred to as a riddim), and the occasional dubbing of vocal or instrumental snippets from the original version or other works.
Dub was pioneered by recording engineers and producers such as Osbourne "King Tubby" Ruddock, Lee "Scratch" Perry, Errol Thompson and others beginning in the late 1960s. Augustus Pablo, who collaborated with many of these producers, is credited with bringing the distinct-sounding melodica to dub, and is also among the pioneers and creators of the genre. Similar experiments with recordings at the mixing desk outside the dancehall scene were also done by producers Clive Chin and Herman Chin Loy. These producers, especially Ruddock and Perry, looked upon the mixing console as an instrument, manipulating tracks to come up with something new and different. The Roland Space Echo was widely used by dub producers in the 1970s to produce echo and delay effects.
Dub has influenced many genres of music, including rock, most significantly the subgenre of post-punk and other kinds of punk, pop, hip hop, post-disco, and later house, techno, ambient, electronic dance music, and trip hop. Dub was a basis for the genres of jungle and drum and bass, as well as a major influence on dubstep, with its orientation around bass and utilization of audio effects. Traditional dub has survived, and some of the originators such as Mad Professor continue to produce new material.
The use of the word dub in a recording context originated in the late 1920s with the advent of "talking pictures" and referred to adding a soundtrack to a film; it is an informal abbreviation of the word double.
