Drum timing test: how even are your subdivisions?

Pick a subdivision, set the tempo and tap every note against the click. Timing Lab shows your early/late distribution, your spread and which part of the beat pulls away.

Speakers, Bluetooth headphones and touch screens add delay. Calibrate once per device: tap exactly with the click and we subtract the average delay from every score.

How to take the timing test

  1. Calibrate input latency once on this device (right-hand panel). It takes 16 clicks.
  2. Choose 8ths, triplets or 16ths and a tempo. Start slow: a clean slow run tells you more than a messy fast one.
  3. Press Start, listen to the one-bar count-in, then tap every subdivision on the pad, the space bar or any key.
  4. Read the distribution: a tall, narrow peak around zero is the goal.

Reading the results

Average offset is where your taps sit relative to the grid. Spread is the standard deviation of your offsets: how far a typical tap lands from your own average. The by position chart splits the offsets by place in the beat (1 e & a, or 1 trip let), which is where uneven subdivisions show up. A common pattern is an "a" that rushes into the next beat.

Click on beats or on every note?

With the click on every note you are matching sounds, which is easier. With the click on beats only, the notes in between come from your own internal subdivision. Use the full click to learn a tempo, then switch to beats only. When that is clean, try the gap click, where the click drops out completely for a few bars.

From a click to a groove

Timing against a metronome is the start; timing against music is the goal. Use the backing track link to open the Studio at the tempo you just tested, read about choosing a tempo and practising with backing tracks, or drill rudiments in the sticking trainer.

FAQ

Questions drummers ask

What is a subdivision test?
The click plays on the beat (or on every note, if you want help) and you tap every subdivision in between: 8th notes, triplets or 16th notes. It shows whether the notes between the clicks are as even as the ones on the click.
What do the early/late numbers mean?
Each tap is compared with the exact time of the note it belongs to. A negative number means you played early (rushing), a positive one late (dragging). The chart counts your taps in 10 ms windows from −100 ms to +100 ms.
What is a good result?
Inside this tool, a tap within ±30 ms is graded clean and within ±60 ms close. Watch two numbers: the average offset (are you consistently ahead or behind?) and the spread (how much your taps scatter around it). Improving the spread usually matters more.
Why is my average always a few milliseconds late?
Usually it is the hardware: audio output, Bluetooth headphones and touch screens add delay. Run the input latency calibration once per device and the correction is subtracted from every score.
Is it free?
Yes. The timing test is free, needs no account and runs entirely in your browser.
