Track structure
Riser
A riser is a sound that climbs in pitch or volume through a build-up, signalling that something is about to land. White noise, a filtered sweep or a rolling snare all do the job.
In practice
A riser is a countdown the whole room can hear, so treat it as a deadline for finishing whatever you started.
Risers almost always run 8 or 16 bars and resolve exactly on a phrase boundary, which makes them easy to count into even on a record you have never heard. Use the incoming track’s riser to signal the change and let it land on the swap; avoid starting a blend during the outgoing track’s riser, because you will be mid-move at the one instant the arrangement demands resolution.

Where it always resolves
Where these come from: Arithmetic from the 4/4 phrase grid and arrangement convention, not counts from our catalog. For what we can measure, see the phrase grid this rests on.
Why it matters
A riser is the clearest instruction a record gives a room, and it is also the clearest instruction it gives a DJ: whatever you are doing needs to be finished. Once a riser starts, the arrangement has committed to a landing point and a transition still in progress will collide with it.
It cuts the other way too. A riser on the incoming track is a very effective way to announce a change while the outgoing record is still playing, because it occupies frequency space nothing else is using and everybody recognises what it means.
Frequently asked
How long is a riser?+
Usually eight or sixteen bars, ending exactly on a phrase boundary — about 15 or 30 seconds at 128 BPM.
What is the difference between a riser and a sweep?+
A riser climbs towards a landing and creates tension. A sweep moves a filter across the whole mix and is used for transition rather than for build — it can go in either direction.
Should you mix during a build-up?+
Finish before it or wait until after the drop. A build points at one specific moment, and a transition still resolving when it lands fights the record instead of riding it.

Build-up
A build-up is the climb out of a breakdown — a riser, a snare roll, filters opening — that tells a floor the drop is coming. It is arranged to land exactly on a phrase boundary rather than wherever it happens to finish.
Sweep
A sweep moves a filter across a sound so its brightness travels — up towards a moment or down away from one. It works as an arrangement element inside a track and as a live move on a mixer.
Drop
The drop is the moment the full arrangement lands after a breakdown — beat, bass and hook arriving together. In most club records it is the point the whole track is arranged around, and the thing a floor is waiting for.
Phrase
A phrase is a block of bars a track is built from, usually 8, 16 or 32. Electronic music changes at phrase boundaries, so a mix that starts on one keeps both tracks structurally in step.
