DJ-ing, or disc jockeying, is the art of mixing recorded music for an audience. DJs select and play tracks, often blending different songs together to create a seamless flow of music. They use equipment like turntables, mixers, and software to manipulate sound, adding effects and transitions to enhance the listening experience. DJs perform at various events, including parties, clubs, and festivals, where they engage the crowd and set the mood. Some DJs specialize in specific genres, such as hip-hop, electronic dance music (EDM), or reggae, while others may play a mix of styles to appeal to a broader audience.
