Online Metronome

Yes. This metronome uses the Web Audio API scheduling engine, not JavaScript setInterval. Audio events are scheduled ahead of time on the audio thread, providing sample-accurate timing that does not drift or jitter — the same technique used in professional DAWs and audio workstations.

The metronome supports tempos from 40 BPM (Grave/Largo) to 300 BPM (extreme Prestissimo). This covers everything from slow classical pieces to the fastest practice exercises.

Click the Tap Tempo button (or press T) rhythmically. The tool averages the intervals of your last 4–8 taps to calculate the BPM. If you pause for more than 3 seconds, the tap buffer resets so you can start fresh.

The metronome supports 2/4, 3/4, 4/4, 5/4, 6/4, 3/8, 6/8, 7/8, 9/8, and 12/8. Compound meters like 6/8 and 12/8 use beat groupings (3+3, 3+3+3+3) for correct accent placement. You can also customize accents manually.

Tempo ramping gradually changes the BPM from a start value to an end value over a set number of bars. This is ideal for building speed in practice — start slow and progressively increase tempo, or use it to practice decelerating (ritardando).

No. This is a pure playback tool. It does not use your microphone, does not record any audio, and does not send any data to a server. Everything runs 100% in your browser using the Web Audio API.

Classical tempo markings are Italian terms that describe the character and approximate speed of a piece. Common reference ranges: Grave / Largo (~40–60 BPM) — very slow and broad; Andante (~66–76 BPM) — walking pace; Moderato (~88–112 BPM) — moderate; Allegro (~120–168 BPM) — fast and lively; Presto / Prestissimo (~168–300 BPM) — very fast. Exact BPM boundaries vary by tradition and era; the marking on this metronome updates automatically as you change tempo so you always see the nearest standard designation.

Indirectly, yes. The accent pattern editor lets you set custom accent grids within a time signature — for example, setting a 3-against-4 pattern manually within 12/8. For true polyrhythm work where two independent click streams play simultaneously, open this metronome in two browser tabs at different BPM values (e.g., one at 120 BPM and one at 90 BPM for a 4:3 ratio). Each tab runs its own independent Web Audio context so the clicks remain independently precise.

For guitar: start a difficult passage at 60–70% of target tempo with the metronome locked to quarter notes, then use the tempo ramp feature to increase gradually — never jump more than 5–10 BPM at a time. For drums: use the subdivision clicks (8th notes or 16th notes) to internalize the grid, then turn subdivisions off and rely on just the downbeats once the rhythm feels solid. Accent patterns help simulate a drummer's natural accent on beat 1 of each bar, making practice feel more musical. If you want to verify you are locking to the beat in real time, the BPM tap tool lets you tap along and see your accuracy.

Yes. BPM changes take effect on the next scheduled beat, so there is no audible glitch — the transition is smooth and sample-accurate. Time signature changes also take effect cleanly at the next bar boundary. Accent pattern edits apply immediately. This makes it possible to practice meter-change passages (e.g., switching between 4/4 and 7/8) without stopping and restarting the click track.
