A disc jockey, commonly known as a DJ, is a skilled music professional who selects and plays recorded music for an audience. They use various equipment such as turntables, mixers, and audio software to mix and blend different songs seamlessly, creating a continuous flow of music. DJs often perform at parties, clubs, radio stations, and other events, entertaining the crowd with their music selection, beatmatching, and sometimes even live remixing. Their goal is to create an enjoyable and energetic atmosphere, keeping the audience engaged and dancing throughout the event.
