Tempo & rhythm
Downbeat
The downbeat is the first beat of a bar — the "one" a DJ counts to. It is where the kick lands hardest and where every phrase, drop and transition is aligned from.
Measured in our catalog
100.0% of the catalog — 443,442 of 443,460 public tracks — reads as 4/4, which is what makes one correct downbeat imply the whole grid.
In a signature where every bar is the same size, finding the "one" once tells the software where every subsequent bar starts. That is the entire basis of automatic beatgridding, and it is why it works so reliably on electronic music and so badly on anything with a live drummer.

Why it matters
Getting the downbeat wrong is the most common way a technically correct mix still sounds wrong. Two tracks can be at identical tempos and perfectly in phase and still be a beat apart on the count, which puts every snare of one record against every off-beat of the other.
It is also what sync buttons do not fix. Software will lock the grids together, but if the grid itself was placed on the wrong beat, sync propagates the error rather than correcting it.
Frequently asked
How do you find the downbeat in a track?+
Listen for where the kick pattern restarts and the bassline resets — usually the same instant. In most dance records it is also where a new eight or sixteen-bar section begins.
What happens if you mix on the wrong downbeat?+
The tempos match and the music does not. Snares land against off-beats and the two records fight rhythmically even though nothing is drifting — pull one out and restart it on the count.
Does the sync button find the downbeat?+
It aligns to whatever the beatgrid says the downbeat is. If the grid was placed a beat late, sync reproduces that error faithfully, which is why grids are worth checking by ear on anything unusual.

Beat
A beat is the steady pulse you tap your foot to — the unit tempo is counted in. Four of them make a bar in the 4/4 time nearly all dance music is written in.
Bar
A bar is four beats in 4/4 time — one full cycle of the kick pattern. DJs count in bars rather than seconds because a bar is the same length of music at any tempo, and seconds are not.
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.
Beatgrid
A beatgrid is the map your DJ software lays over a track marking where every beat falls. Once it is right, sync, looping and quantise all work; once it is wrong, everything built on top of it is wrong too.
