Planning and preparing a DJ set comes down to four moves: know the slot, pack about twice the music you will need, plan your first three and last three tracks, and leave the middle open. The same routine works for a one-hour bar slot and a three-hour club night.
Ask about the slot before anything
Before you pick a track, ask the promoter or the venue four things:
- When you play. Opening (the room is filling up), peak (it is full) or closing (it is thinning out). An opening set that goes straight to peak-time tracks empties the floor and leaves nothing for the headliner.
- How long. One hour is a statement. Three hours is a journey with room to breathe.
- Who plays before and after you. Listen to a recorded set of each. You start on their tempo and hand over something the next DJ can use.
- The room and the system. A small bar and a big club reward different records. Ask what is in the booth (players, mixer or controller, laptop space) so you know what to bring.
Write the answers down.
How much music to bring
A rule of thumb: you will play about 15 to 20 tracks per hour, because most dance tracks run five to seven minutes and you rarely play them to the end. Fast styles like drum and bass burn through more; slow, long-blending styles use fewer. Then pack at least double that. The extra half lets you change direction when the room surprises you.
| Set length | Tracks you will play | Tracks to pack |
|---|---|---|
| 1 hour | 15 to 20 | 30 to 40 |
| 2 hours | 30 to 40 | 60 to 80 |
| 3 hours | 45 to 60 | 90 to 120 |
Rules of thumb, not rules. Count your own last set to calibrate.
Build the crate
A crate is the list of tracks you bring to one gig. Fill it from four places:
- Recent finds. Usually the biggest group, and the least tested.
- Proven tracks. Tracks that worked for you before, or that keep showing up in other DJs' sets. On Digger Digger every track shows how many recorded DJ sets it was found in ("88 sets" means 88 different sets), a quick way to spot what works on real floors.
- Two or three surprises. An old record, something from a neighboring style, a vocal nobody expects. One per hour is plenty.
- Rescue tracks. Three or four tracks that always work, in their own folder. When a blend falls flat, you reach for one without thinking.
Save them with the crate button as you dig, then send the crate to your DJ app a week ahead, so you have time to live with the new tracks. Once My crate holds three tracks or more, Order my set puts them in a first draft of set order, from warm-up to peak, by BPM, key and energy. Treat it as a starting point and move tracks around.
Plan the arc, then fix six tracks
Every set has the same shape: an opening that sets tempo and mood, a build where the energy rises in steps, one or two peak moments, a release after each peak so the room can breathe, and a close. Sketch where each part falls in your slot. In a one-hour peak set the opening is two tracks long. In a three-hour set the build alone can take an hour.
Now fix only six tracks: the first three and the last three. The first three lock the tempo with whoever played before you and tell the room who you are. The last three are the ending you want to be remembered by. Add one more: the moment you are building toward, the one track you know will land. Everything between those points stays open.
It stays open because the room decides, not the plan. Look up every minute. Are people moving toward the speakers or the bar? If the room is ahead of your plan, skip forward. If it is behind, stay longer where you are. Reading the room is not a gift; it is looking up and reacting. For an example in one style, see how to build an afro house set that actually lands.
Technical prep
Once the crate is in your DJ app, prepare each track so you never hunt mid-mix:
- Cue points (saved markers you can jump to) at the first usable beat of the intro and at the first drop, where the full beat lands. Two per track is enough.
- Beatgrids (the app's map of where the beats fall) on anything with live drums, a long beatless intro, an old recording or an edit. Analysis often gets these wrong, and a bad grid breaks sync and loops. Check them by ear at home.
- Keys. You do not need a key path for the whole set; you need to know which tracks clash with your fixed six. Harmonic mixing explained covers the three safe moves.
- Tempo ranges. Sort the crate by BPM (beats per minute) and look for gaps. If it jumps from 124 to 132 with nothing between, you cannot get there smoothly.
- Gain (the input level of each track). Loudness differs between tracks, labels and decades. Set the gain so the meters match from one track to the next.
Practice, then record a run
Rehearse the transitions that matter: into and out of the fixed six, and any blend where two melodies overlap. Then play a full run at home and record it. Listen the next day, away from the decks. You will hear bass clashes, a vocal over a vocal and an effect used four times too many. Fix the crate, not the recording.
The bag
Pack the night before, from a list. The three things DJs forget most are the three they cannot play without: USB sticks, headphones and the headphone adapter.
- Two USB sticks with the same music, or your laptop plus a backup stick. Test both in a real player if you can. Laptop or USB stick covers which to bring.
- Headphones and the 6.35 mm (quarter-inch) adapter. Most booth mixers have no 3.5 mm socket.
- If you play from a laptop: charger, sound card or controller, every cable, and a spare of the one you cannot replace at 1 a.m.
- Earplugs, water, the promoter's number and the time you need to be there.
On the day, and after
Arrive at least half an hour before your slot. Listen to the DJ before you from the floor: their tempo, their energy, what the room reacts to. Your first track should sit at their last tempo. In the booth, load your first two tracks, check both channels in your headphones, and set the booth speaker to a level you can live with. That is your soundcheck, and it takes two minutes.
The next day, open the crate. Note what worked: the blends that landed and the track that turned the room. Move those into a playlist called "tested", your starting point next time. Move the duds out: the track that cleared the floor, the one that never fit. Half an hour, and your next set starts from a better crate.
Quick answers
How many songs do I need for a one-hour DJ set? You will play about 15 to 20, so pack 30 to 40. Fast styles like drum and bass use more, slow long-blending styles fewer.
Should I plan every track of my set? No. Fix the first three and the last three, plus the one moment you are building toward, and let the room decide the rest.
How far ahead should I prepare? Have the crate in your DJ app about a week before the gig, so you can live with the new tracks, check grids and cues, and record one practice run.
Does the plan change if I open or close the night? Yes. An opener builds the room and leaves the peak to the next DJ; a closer brings the energy down to an ending people remember. See what to play when you open for a big DJ and how to close a DJ set.
The best preparation is a crate full of tracks you trust. Pick your style, sort by the number of sets, and start from the tracks the big DJs keep coming back to.
