Dub is a genre of music which grew out of Reggae music in the 1960s, and is commonly considered a sub-genre though it has developed to extend beyond the scope of Reggae. Music in this genre consists predominantly of instrumental remixes of existing recordings and is achieved by significantly manipulating and reshaping the recordings.
Usually this is done by removing the vocals from an existing music piece, and emphasizing the drum and bass parts (this stripped down track is sometimes referred to as a 'riddim'. Other techniques include dynamically adding extensive echo, reverb, panoramic delay, and occasional dubbing of vocal or instrumental snippets from the original version or other works.
Dub has influenced many genres of music, including Rock, most significantly the sub-genre of Post-Punk and other kinds of Punk, Pop, Hip Hop, Disco, and later House Techno. Dub has become a basis for the genres of jungle drum and bass dub step.
