Kuon Metronome
A free metronome, in your browser. Nothing to install, nothing that drifts.
No sign-up. It sounds the moment you open it. Each beat is scheduled ahead against the audio clock, so it does not drift as time passes.
Silent bar practice, speed trainer, polyrhythm, swing, irregular meter grouping, metric modulation, clave patterns, beat displacement, over-the-barline, all 13 features a pro actually needs. Browser-based, free.
The problem with existing metronomes
"Just plays clicks", can't train you to internalize tempo
No irregular meter practice. 5/8, 7/8 and 11/8 unsupported
No polyrhythm training available
Metric modulation training doesn't exist
Can't play clave or jazz patterns alongside
Why this metronome is different
Most metronome apps are built by developers. Developers can write code, but they don't know what's needed in the practice room. Silent bar practice, polyrhythm, metric modulation, clave patterns, every feature of KUON METRONOME comes from real practice needs.
Core. Nine professional tools
Silent Bar Practice
Play N bars, then N bars silent. Drift on return reveals internal pulse accuracy.
Speed Trainer
Auto-accelerate from start to target BPM every N bars.
Polyrhythm
4:3, 3:2, 5:4, two rhythms in different timbres simultaneously.
Irregular Meter Grouping
7/8 as 2+2+3 or 3+2+2. Full support for 5/8 through 12/8.
Swing
50% (straight) to 75% (full triplet) continuously adjustable.
Subdivisions
Eighth notes through septuplets. Off-beats at distinct volume.
Accent Pattern
4 levels per beat (strong/medium/weak/mute). Click to change.
Tuning Reference
A=440-443Hz sine wave alongside the metronome.
Presets
Save BPM, time sig, subdivision and accents as one set. Recall in one tap.
Jazz Training. Four training features
No other browser metronome offers these features.
Metric Modulation
♩=♩. (tempo×2/3), triplet ♩=new ♩ (×3/2), ♩=♪ (×2), quintuplet modulation, 4/4→3/4→4/4 chain, tempo transitions based on beat equivalence, auto-played as multi-bar sequences. 5 built-in presets with loop support. The most advanced jazz/modern music training, in a browser.
World Rhythms
Son, Rumba and Bossa Nova claves, Shiko, Soukous, Gahu, Bembé (12/8 standard bell), Tresillo, Cinquillo, Habanera, Jazz Ride on a true triplet grid, Middle Eastern iqa‘at (Maqsum, Baladi, Saidi, Malfuf, Ayyub), Balkan dances (Rachenitsa, Kopanitsa...), Hindustani talas (Tintal...), a curated library of source-verified rhythms only, played alongside the metronome with dot visualization.
Beat Displacement
Shift accent by 1/16, 1/8, 3/16, or 1/4 note. A displaced click sounds alongside the normal click. Practice phrasing on the "shifted downbeat", the most essential rhythm technique in jazz improvisation.
Over the Barline
Accent every 3 beats in 4/4 → completes in 4 bars. Every 5 → 5 bars. Every 7 → 7 bars (Coltrane-style float). 4 over 3/4 overlays 4-feel on a waltz. Cross-barline accents engrave jazz phrasing "float" into your body.
Millisecond-level Precision
JavaScript's setInterval has ±10ms jitter, unacceptable for musicians. KUON METRONOME uses Web Audio API's AudioContext.currentTime with look-ahead scheduling. Sample-accurate timing that professionals can trust.
Perfect For
Music exam candidates training rhythmic sense in ear training
Every instrumentalist wanting to internalize tempo
Advanced players mastering polyrhythm and irregular meters
Jazz musicians training metric modulation
Latin/Jazz players engraving clave into their body
Students wanting tempo training during commute

Use KUON METRONOME (Free)FAQ
Why does a metronome drift?
Usually because the click is triggered by the screen timer, which can be pushed around by other work and drift by tens of milliseconds, and that adds up. The Kuon metronome schedules each beat ahead of time against the audio clock itself, so the moment a click sounds does not move even when the page is busy.
Is it really free? Do I need an account?
It is free. No account, no login. It sounds the moment you open it, and there are no ads.
Do I need to install an app?
No. Just open it in a browser. It works the same on a phone and on the practice-room computer. Add it to your home screen and it opens in one tap next time.
Can I practise odd meters and polyrhythms?
Yes. You can build any meter. It also includes stacking two pulses at once, muting bars so you check your own time, and stepping the tempo up gradually.
Can I set the tempo by number?
Yes. Type the number directly, nudge it with the arrow keys, or tap along with the music to set it.
The Rhythms of the World
Cuban clave, Arabic iqa, Balkan aksak, Indian tala. Twenty-eight patterns verified against the literature down to every stroke, all playable on the page, with interval vectors and the rotations that connect one tradition to another.
