Decide the shape of the night before you open your library. Pick a slot length and a shape, and get an energy target for every track, the curve drawn out, and what each section is for — then print it and take it to the booth.
Energy is how hard a record pushes. Mixed In Key and rekordbox both rate it from 1 to 10, and their numbers are a fine starting point, but the rating is yours to override, because the analysers hear loudness and density where you hear intent. Five things move it:
Rate your library once, in the tags, and the planner's targets become a search: "I need an 8A at 126 that sits around 6." That is exactly how a prepared set gets built in a fraction of the time.
| Shape | When to use it | The trap |
|---|---|---|
| The climb | A headline slot, or any set where you own the end of the night. One long rise to a single late peak, then a landing. | Peaking too early. If you hit 9 at the halfway mark there is nowhere left to go. |
| Double peak | Long sets — 90 minutes and up. Nobody sustains an hour and a half of climbing, and the dip is what makes the second peak land. | A dip that is not deliberate enough. Drop two or three points, not one, or the room reads it as a stumble. |
| Plateau | A 60-minute festival slot between two other DJs. Get to the level fast, hold it, leave. | Boredom. Holding a level means varying texture — vocals, breaks, genre — not level. |
| Slow burn | Warm-up. The job is to build a room and hand it over below where the next act starts. | Peaking. The warm-up DJ who plays the headliner's records at 11pm is noticed, and not kindly. |
These are the same four shapes as the set length calculator and the planning guide, with the same section boundaries. The planner adds the missing axis: not just how long each section runs, but how hard each track in it should hit.
It is tempting to build energy with the pitch fader — start at 122, finish at 130. The data says DJs do not. Across published sets the median tempo is 126 BPM in the first third, the middle third and the last third. What changes across a set is the selection: heavier drums, denser basslines, more insistent vocals, less space. The late-set widening in the tempo spread is DJs reaching for something unusual once the room is committed — a faster record, or a much slower one — a widening of options, not a ramp.

So the planner never prints a BPM target. If your genre sits at 126, plan on 126 the whole way and spend the fader on matching, not on climbing.
The printed plan is a row per track: its time, its section, and its energy target. It is not a tracklist. The point of planning the arc first is that the records can change on the night — the room is warmer than you expected, the DJ before you finished high — while the shape does not. If you are two tracks in and the floor is already where your plan says it should be at track eight, skip forward on the plan, not off it.
The targets are also what you check candidate records against when you prepare. A track that is right in key and tempo but a 4 where the plan wants a 7 is the wrong track — a mistake the tags alone will never catch, and the one that most often separates a set that flows from a set that merely works.
How hard a record pushes a room, usually rated 1 to 10 the way Mixed In Key and rekordbox do it. It is set by drum density, bass weight, how insistent the vocal or lead is, how big the drops are and how little space is left in the mix. It is not tempo: a 126 BPM warm-up cut and a 126 BPM peak-time record are the same speed and nothing like the same energy.
In a shape you chose before you picked the records. The four that cover most slots are a single climb to a late peak, a double peak with a deliberate dip between, a plateau that gets up fast and holds, and a slow burn for a warm-up that finishes below where the next DJ starts. Rise by about one energy point every two or three tracks; jumps of three or more read as a gear change and should land on a drop.
No. Across published sets the median tempo is 126 BPM at the start, in the middle and at the end. Energy rises through selection and arrangement, not through the pitch fader. Planning a tempo ramp forces you to reject records that fit the moment for arithmetic reasons; plan the energy instead and let tempo stay roughly flat.
