Dub is a form of music, evolved from reggae that involves revisions of existing songs. The dub sound 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, emphasizing the drum and bass frequencies or 'riddim', adding extensive echo and reverb effects, panoramic LR delay, and dubbing occasional snippets of lyrics from the original version.

Reggae is a music genre first developed in Jamaica in the late 1960s.

While sometimes used in a broader sense to refer to most types of Jamaican music, the term reggae more properly denotes a particular music style that originated following on the development of ska and rocksteady. Reggae is based on a rhythmic style characterized by regular beats on the off-beat, known as the skank. Reggae is normally slower than ska, and usually has accents on the first and third beat in each bar.
