About the online metronome
This online metronome keeps a steady beat for music practice. Set the tempo in beats per minute (BPM) and the number of beats per bar, and it plays an accented click on the first beat with a visual pulse. Accurate timing is generated with the Web Audio API in your browser — no app needed.
How Metronome works
How to use the metronome
- Set the tempo (BPM) with the slider.
- Choose how many beats are in each bar.
- Press Start — the first beat of each bar is accented.
Accurate timing
The clicks are scheduled with the Web Audio clock, which is far more precise than a simple timer, so the beat stays rock-steady. Press Start once to enable sound in your browser.
Practice tips
Start slow and increase the tempo as you improve. Practising with a metronome builds steady timing and makes tricky passages easier.
