Dub is a 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, emphasis of the rhythm section (the stripped-down drum-and-bass track is sometimes referred to as a riddim), the application of studio effects such as echo and reverb, 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, Hopeton "Scientist" Brown, 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.
