Rap is the art of performing spoken-word style, rhythmic lyrics, primarily associated with Hip-Hop music. Rap also refers to the lyrics themselves. This tag is for the writing and performing of rap lyrics. Although the term is often used synonymously with hip-hop to refer to the style of music, the [rap] tag should be reserved for lyrics, with the [hip-hop] tag reserved for the musical style/genre. Both tags may be appropriate.
Rap is a form of vocal delivery that incorporates "rhyme, rhythmic speech, and street vernacular", which is performed or chanted in a variety of ways, usually over a backing beat or musical accompaniment.
