A disc jockey (also known as disk jockey, DJ or deejay) is a person who selects and plays recorded music for an audience. Originally, disk referred to phonograph records, while disc refers to the Compact Disc, and has become the more common spelling. There are several types of disc jockeys. Radio DJs introduce and play music that is broadcast on AM, FM, shortwave, digital, or internet radio stations. Club DJs select and play music in bars, nightclubs, discothèques, at raves, or even in a stadium. Hip hop disc jockeys select and play music using multiple turntables, often to back up one or more MCs, and they may also do turntable scratching to create percussive sounds. In reggae, the disc jockey (deejay) is a vocalist who raps, "toasts", or chats over pre-recorded rhythm tracks while the individual choosing and playing them is referred to as a selector.[1] Mobile disc jockeys travel with portable sound systems and play recorded music at a variety of events.
