A good DJ set starts before you arrive at the venue. Preparation reduces stress, protects your reputation, and gives you more freedom to focus on the room.
Before the gig, confirm the basics: date, arrival time, set time, location, payment, contact person, dress code, expected crowd, music boundaries, and equipment provided. If anything matters, get it in writing.
Prepare your music for the event, not just for your taste. Think about the room, the time slot, the people before and after you, and how much flexibility you need. A warm-up set requires different discipline than a peak-time set.
Bring backups. At minimum, consider backup USBs, a second copy of your library, extra cables, headphones, adapters, and a small emergency playlist that can save the room if your plan fails.
During the gig, watch the crowd without surrendering your taste completely. A DJ is not a jukebox, but the room is always giving information.
After the gig, write notes: what worked, what failed, which tracks surprised you, what questions the venue asked, and what you would do differently next time.
Professionalism is built from small habits. The more prepared you are, the more creative you can be in the moment.
