About Metronome
What an online metronome is for
A metronome plays a steady, audible click at a chosen tempo so you can practise music, train running cadence, or pace any rhythmic activity. The clicks are measured in BPM (beats per minute): 60 BPM is exactly one click per second; 120 BPM is two per second; 180 BPM is the running-cadence sweet spot.
This tool is a full-featured browser metronome — no install, no account, no ads in the click stream. It uses the Web Audio API for sample-accurate timing (so it doesn't drift over long sessions) and pairs every click with synchronised visuals: a pulsing orb, an optional pendulum arm, beat dots that highlight the downbeat, and an oscilloscope-style wave graph that shows the tempo rhythm at a glance.
Features at a glance
- 30–300 BPM range with ±1 / ±5 BPM keyboard nudging, an Italian tempo label (Largo, Andante, Allegro…), and one-tap presets at every common tempo.
- Tap tempo — tap a button or press
Tto set BPM by feel. Uses a rolling 8-tap average for accuracy. - Time signatures: 2/4, 3/4, 4/4, 5/4, 6/8, 7/8 — with a louder, brand-coloured downbeat.
- Subdivisions: quarter, eighth, triplet, sixteenth — each at a distinct pitch.
- Four click sounds: classic click, wood block, digital beep, and bell. Audition each instantly.
- Visual pulse: orb scales on every beat, halo glows on downbeats, pendulum arm swings in sync.
- Wave graph: scrolling oscilloscope showing the past few seconds of beats — handy for visually verifying your settings.
- Speed trainer: gradually ramp BPM (e.g. 60 → 140, +5 every 4 bars) for practising scales or runs at incremental tempos.
- Visual-only mode: keep the animations, mute the sound — perfect for quiet rooms.
- Keyboard shortcuts:
Spaceplay/pause,↑↓±1 BPM,←→±5 BPM,Ttap. - Shareable presets: save a BPM + time signature combo as a link.
- Saved automatically to your browser, and respects

Why use a metronome
The single biggest fix for sloppy timing in any instrument is practising slowly with a metronome and bumping the tempo up in small steps. Modern guitar / piano / drum teachers all recommend this pattern, and the speed-trainer mode automates it. Beyond music, metronomes are used for:
- Running cadence (180 BPM is the efficiency target popularised by coach Jack Daniels).
- CPR compressions (100–120 BPM — "Stayin' Alive" tempo).
- Public-speaking pace, rowing stroke rate, and knitting / data-entry rhythm.
How tempo terms map to BPM
- Largo — 40–60 (slow, broad)
- Adagio — 66–76 (slow, stately)
- Andante — 76–108 (walking pace)
- Moderato — 108–120 (moderate)
- Allegro — 120–168 (fast, cheerful)
- Presto — 176–200 (very fast)
- Prestissimo — 200+ (extremely fast)
The page shows the term live as you change the BPM so you can match the marking on your sheet music.
Frequently asked questions
Yes — it uses the Web Audio API's `AudioContext` scheduler with a 100 ms look-ahead, so individual clicks are scheduled in advance against the audio clock. Unlike a `setInterval` loop, that doesn't drift over long sessions and stays tight even when the tab is in the background (browser permitting).
Click the "Tap tempo" button repeatedly to the beat — or press the `T` key. After two taps the BPM jumps to the matched tempo, and accuracy improves with each additional tap (it averages the most recent 8). Pause for more than 2 seconds and the next tap restarts the average.
Yes — the time-signature picker includes 2/4, 3/4, 4/4, 5/4, 6/8 and 7/8. Beat 1 of each bar is automatically accented (louder click + larger pulse), so polyrhythmic and odd-meter practice work out of the box.
Practising a piece "from slow to fast". You set a start tempo, an end tempo, an increment (e.g. +5 BPM) and how many bars to spend at each step. The metronome counts bars and bumps the BPM automatically — a more disciplined version of doing it by hand. Great for scales, sight-reading drills, and shredding licks.
The pendulum is the classic mechanical-metronome aesthetic — your peripheral vision can lock onto its arc even when your eyes are on your instrument. The oscilloscope wave shows the past few seconds of beats so you can verify a setting is right without listening through a full bar. Both can be toggled off if you prefer the minimal view.
Yes — once the page is loaded everything runs in your browser. The audio engine, visuals, presets, and saved settings all work offline. You can also install it as a PWA from the prompt and launch it from your home screen.
300 BPM is the upper limit. Above ~240 BPM individual clicks start to blur into a pitch for the human ear, and at 300+ BPM most physical instruments can't play distinct notes anyway. If you need faster, lower the subdivision (e.g. set 150 BPM with sixteenth notes for the equivalent of 600 ticks/min).
Toggle "Visual only (mute)" in the Sound panel. The pulse, pendulum, beat dots, and wave graph keep going — the clicks just stop. Useful for silent practice rooms, late-night sessions, or visual training for deaf / hard-of-hearing musicians.
