A DJ, short for disc jockey, is a professional who plays and mixes recorded music for a live audience. They are skilled in selecting and blending tracks to create a seamless flow of music for dancing or listening at events such as parties, weddings, clubs, or festivals. DJs use various equipment such as turntables, CDJs, laptops, and mixers to manipulate and transition between songs. They often have a deep knowledge of music genres, trends, and audience preferences to cater to different audiences and create an enjoyable experience. DJs may also produce their own music, remixes, and mashups to showcase their unique style and creativity.
