Dub is a
genre of
electronic music that grew out of
reggae in the 1960s, and is commonly considered a
subgenre, 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 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.
