Bar Counter: count it like a DJ
The count DJ teachers use: say the bar number on the one, then the beats 2, 3, 4. ONE-2-3-4, TWO-2-3-4, THREE-2-3-4, FOUR-2-3-4, then start again. Press Play to hear it, or load a track and hit ONE on its first downbeat to count along.
4 phrases make 32 bars. The big moments, like a drop or a breakdown, usually land at the start of one of those 32-bar blocks.

How DJs count
Dance music is built in blocks. Four beats make a bar. Eight bars make a phrase. Four phrases make a 32-bar block. Producers change something at almost every phrase line, so if you know where the phrases are, you know when the track is about to change.
Counting every beat up to 32 is hard while you also cue a track. So DJs put the bar number on the one:
- ONE-2-3-4, TWO-2-3-4, THREE-2-3-4, FOUR-2-3-4
- then again: ONE-2-3-4 … FOUR-2-3-4
Two rounds of that is one 8-bar phrase. The big number tells you which bar you are on. The small numbers keep you in time. You stop counting beats and start counting bars, which is what you actually need when you mix.
Once that feels easy, switch the counter to Count to 8 bars. Then the big number runs ONE to EIGHT and starts again exactly on each new phrase.
How to find the one
The one is the first beat of a bar. It feels heavier than the other three. These are the easiest places to hear it:
- The first beat of the drop. Always a one, and always the start of a phrase.
- A crash cymbal. Producers hit one on the one to mark a new section.
- Something new comes in, like a hi-hat, a bassline or a vocal.
- The first kick after a breakdown. The build points straight at it.
If your count says FIVE and the music clearly just changed, trust the music. You are at ONE.
Use it with your own track
- Choose a track under Count along to your own track. It stays on your device.
- Type its BPM, or press Tap tempo in time with the kick a few times.
- Press Play. The track starts with the counter.
- Press ONE on the first beat of a bar, like the first kick of the drop. That beat becomes bar 1, beat 1.
- Watch the grid. The cell turns violet on each new phrase. Listen for what changes there.
Do this with a few tracks you know well. You'll start to hear the phrase coming before the counter shows it, and that's the skill. Our guide to learning to DJ with your own music has more practice ideas.
Why phrases matter for mixing
Beatmatching keeps the kicks together. Phrasing keeps the sections together. If you start the next track on a phrase line, its drop lands where the old track would have changed anyway, and the mix sounds planned. Start it a bar off and the drop arrives in the middle of a section. The crowd hears that, even when the beats are perfect.
Read the full guide to DJ phrasing and how to mix on the phrase, then work out exactly when to start a transition. If you want the sums done for you, the When to Mix In calculator tells you when to press play, in time and in bars. And once your phrases line up, the Camelot wheel helps you pick tracks whose keys fit too.

Frequently Asked Questions
How do DJs count bars?
They say the bar number on the first beat of each bar and the beat numbers after it: ONE-2-3-4, TWO-2-3-4, THREE-2-3-4, FOUR-2-3-4, then back to ONE. Two rounds of that, or one round counting to eight, is a phrase of 8 bars. Putting the bar number on the one means you always know which bar you are on without counting every beat.
How many beats are in a bar, and how many bars are in a phrase?
In house, techno, trance and drum and bass a bar is 4 beats and a phrase is 8 bars, so a phrase is 32 beats. Four phrases make a 32-bar block of 128 beats, which is about a minute at 124 BPM. Drops and breakdowns usually land at the start of one of those blocks.
How do I find the one in a track?
Listen for the heaviest beat: the one where a crash cymbal hits, a new sound comes in or the bassline restarts. The first kick after a breakdown or a build is almost always the one, and so is the first beat of the drop. Press ONE on the Bar Counter as that beat lands and the count starts from bar 1 there.
Can I count along to my own music?
Yes. Choose a track under "Count along to your own track", set the BPM (or tap it), press Play, then press ONE on the first beat of a bar. The track plays in this page only. Nothing is uploaded, and the click turns off so you hear the music and see the count.
What does counting to 4 or 8 bars mean?
It is how high the big number goes before it starts again. Counting to 4 gives ONE to FOUR twice per phrase, which is what most teachers start with. Counting to 8 gives one number per bar of the phrase, ONE to EIGHT, so the count resets exactly on each new phrase.
Why does phrasing matter when I mix?
If you start the next track on a phrase line, both tracks change at the same moment and the mix sounds like one long record. Start it a bar or two off and its drop lands in the middle of the other track’s section, which sounds wrong even when the beats are perfectly matched.
