Free Online Metronome with Visual Beat Indicator
Practice your instrument with this precision online metronome featuring tap tempo, multiple time signatures, subdivisions, and a real-time visual beat indicator. No downloads, no signups, no ads.
Why AI Cannot Replace This Tool
AI chatbots can describe a metronome or suggest practice tempos, but they cannot generate real-time audio clicks with precise millisecond timing. Steady beat generation requires continuous browser execution and Web Audio API scheduling that AI models cannot provide. This is a pure problem-solver for musicians who need actual timing, not just advice about timing.
How to Use
- Start / Stop — Press Start (or the Spacebar) to begin the beat. Press again to stop. The metronome uses your browser's Web Audio API for precise timing.
- Adjust Tempo — Drag the BPM slider or type a value (20–300) in the number box. The Italian tempo marking updates automatically.
- Tap Tempo — Tap the Tap Tempo button at least 3 times at your desired speed. The metronome calculates the average BPM and updates automatically.
- Time Signature — Choose from 2/2, 2/4, 3/4, 4/4, 5/4, 6/8, 7/8, 9/8, or 12/8. The first beat of each measure is accented (red dot).
- Subdivisions — Select quarter, eighth, triplet, or sixteenth notes. Subdivisions add extra clicks between main beats.
- Sound — Choose between Click, Beep, Woodblock, or Cowbell sounds, all synthesized via Web Audio.
- Volume — Use the volume slider or type a percentage.
- Presets — Click any Italian tempo name (Largo through Presto) to jump to that tempo range.

Frequently Asked Questions
How does the online metronome work?
It uses the Web Audio API built into your browser to generate precise audio clicks. A scheduler runs every 25 milliseconds, computing exactly when each beat should occur and scheduling audio events ahead of time for accurate timing regardless of system load.
Is this metronome as accurate as a physical one?
Yes, the Web Audio API provides sample-level audio timing precision (measured in microseconds), which is more accurate than most mechanical metronomes. The schedule-ahead technique ensures clicks arrive at the exact millisecond regardless of browser tab focus.
Why might the metronome stop clicking?
The metronome may stop if you close the browser tab, navigate away, or if your device's CPU is overloaded. Most browsers also pause audio when the tab is backgrounded to conserve resources.
Can I use subdivisions?
Yes. Use the Subdivision dropdown to add eighth notes (2 ticks per beat), triplets (3 ticks), or sixteenth notes (4 ticks). Subdivisions help practice faster passages and complex rhythms.
What is tap tempo?
Tap tempo lets you find the BPM of a song or your ideal practice speed by tapping a button in time. After 3 or more taps, the metronome calculates the average interval and sets the BPM automatically.
