Hip hop music, also called hip-hop, rap music, or hip-hop music, is a music genre consisting of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching, break dancing, and graffiti writing. Other elements include sampling (or synthesis), and beatboxing.While often used to refer to rapping, "hip hop" more properly denotes the practice of the entire subculture. The term hip hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip hop music; the genre may also incorporate other elements of hip hop culture, including DJing and scratching, beatboxing, and instrumental tracks.Origin of the termCreation of the term hip hop is often credited to Keith Cowboy, rapper with Grandmaster Flash and the Furious Five. However, Lovebug Starski, Keith Cowboy, and DJ Hollywood used the term when the music was still known as disco rap. It is believed that Cowboy created the term while teasing a friend who had just joined the U.S. Army, by scat singing the words "hip/hop/hip/hop" in a way that mimicked the rhythmic cadence of soldiers marching. Cowboy later worked the "hip hop" cadence into a part of his stage performance, which was quickly used by other artists such as The Sugarhill Gang in "Rapper's Delight".
