Disc jockey (DJ) stands for the individual who plays and manipulates music, typically using turntables and a mixer, to entertain audiences. The term originates from early radio personalities who introduced and played records on the airwaves. Modern DJs create seamless transitions between tracks, perform live remixes, and incorporate various techniques like beatmatching and scratching to enhance their performances. They play a vital role in the music industry, performing at clubs, festivals, and other events, catering to diverse musical genres and catering to the tastes of their audience.
