A D.J. (Disc Jockey) is a person who plays recorded music for an audience. They often work at events like parties, weddings, and clubs, mixing different tracks to create a continuous flow of music. D.J.s use various equipment, including turntables, mixers, and digital software, to manipulate sound and enhance the listening experience. In addition to playing music, D.J.s may also create their own remixes or original tracks. They often specialize in specific genres, such as hip-hop, electronic dance music (EDM), or rock. A successful D.J. can engage the crowd and set the mood for the event.
