Rhythm Trainer
Rhythm Trainer is a free online rhythm practice tool with a tap test that scores your timing. Tap along to a click in any of 14 time signatures — beats, eighth notes, triplets, sixteenths, swing and more — and see how early or late every note landed. Then learn 17 grooves, from a basic rock beat and the son clave to polyrhythms, and build your own step patterns.
How to test and improve your rhythm
- 1
Choose what to practice
Open the Tap Trainer and pick a subdivision (beats, eighth notes, triplets, sixteenths, swing and more), a time signature and the number of measures.
- 2
Set the tempo
Choose a tempo you can play accurately. Tempo is counted in quarter notes, from 20 to 300 BPM.
- 3
Tap along
Press Start tap test, listen to the one-measure count-in, then tap every note on the pad or with Space or Enter. Turn the subdivision guide off to place the notes between the beats yourself.
- 4
Read your score
When the last measure ends, each tap is matched to its nearest note. You get a score out of 100, your average timing error, how consistent you were, any missed or extra taps, and a chart of every note.
- 5
Practice patterns
Use Patterns to hear 17 grooves layer by layer, Subdivisions to hear any subdivision in any meter, the Builder to loop your own rhythm, and Exercises for guided practice.
Why rhythm practice matters
Timing is what makes a band sound tight. Deliberate rhythm practice — isolating one subdivision, counting it out loud and playing it against a click slowly before speeding up — trains how accurately you feel the beat, and it carries over to every instrument.
Practice with a score, not just a click
A metronome tells you where the beat is but not where you played. The tap test measures every note, so you can see whether you rush the '&', drag through a measure or drift across the whole test, and then work on exactly that.
From the first beat to polyrhythms
Start with beats and eighth notes in 4/4, move on to triplets, sixteenths and swing, then odd meters like 5/4 and 7/8. The pattern library and exercises lead from a basic rock beat through the son and rumba clave to 3 against 4 and 5 against 4 polyrhythms.
Frequently Asked Questions
What is a rhythm trainer?
A rhythm trainer is a practice tool that plays a steady reference and checks how accurately you play in time. This one plays a click track, records your taps and scores every note against where it should have landed.
How is the tap test scored?
Each tap is matched to its nearest note. Timing is 100 minus your average error in milliseconds. Consistency is 100 minus how much your errors vary, so a steady early or late habit stays consistent but loses timing points. Accuracy is the notes you hit out of all the notes plus any extra taps. Your score is accuracy × (60% timing + 40% consistency).
What is a good score?
Grades run S (95 and up), A (85), B (70), C (55), D (40) and F. Landing within 20 milliseconds of a note, the green band in the timing chart, counts as on time.
Why do my taps measure late?
Part of the delay can come from your device. The trainer allows for the audio latency your browser reports, but Bluetooth headphones can add well over 100 ms that browsers don't always report. If every tap is late by a similar amount, use wired headphones or the device's speaker.
What is the difference between swing and dotted rhythms?
Both split each beat into a long and a short note. Swing uses the first and last note of a triplet, a 2:1 ratio; a dotted eighth and sixteenth is 3:1. At 120 BPM swung eighths last 333 and 167 ms and dotted ones 375 and 125 ms. The Subdivisions tab shows these lengths at any tempo.
What is the difference between son clave and rumba clave?
Both have five notes across the pattern. In the 3-2 son clave the third note falls on the & of 2; in the rumba clave it comes a sixteenth later, on the a of 2. The bossa nova clave keeps the son clave's first four notes and moves the last one from beat 4 to the e of 4.
How does tempo work in 6/8 or 7/8?
Tempo is counted in quarter notes and each beat is the time signature's bottom note, so in 6/8 at 120 BPM each eighth-note beat lasts 250 ms. Louder clicks mark the start of each beat group: 3+3 in 6/8 and 3+2+2 in 7/8.
Is the rhythm trainer free?
Yes, it is completely free with no signup and no limits.
Is it useful for drummers?
Yes. Drummers, guitarists, bassists, pianists and singers all benefit from steadier time and cleaner subdivisions, and the pattern library includes drum grooves such as the rock beat, a funk groove and the blues shuffle.
