Sample-accurate WebAudio clicks with look-ahead scheduling and beat dots

Tap tempo (last 4 taps), accented downbeat, 2/4 3/4 4/4 6/8, no audio files.

Quick answer: A precise 30–240 BPM metronome with tap tempo, 2/4 to 6/8 time signatures, accented downbeat and visual beat dots — all synthesized in your browser.

Set a tempo (or tap it), pick a time signature, press Start.

How to use

  1. Set 30–240 BPM or tap ≥2 times for tap tempo.
  2. Choose a time signature → Start.
  3. Watch the dots — the red dot is your accented downbeat.

About this tool

Practice like the pros: a Web Audio metronome with a look-ahead scheduler that stays sample-accurate even when the browser tab gets busy — the classic timing drift of naive metronomes is avoided here. Slide 30–240 BPM, tap tempo at least twice to auto-detect the pace of the music in your head, choose 2/4, 3/4, 4/4 or 6/8, and hear the accented downbeat click higher than the other beats while visual dots track the measure. All clicks are synthesized oscillators on your device — no audio files, no network, no cost, no ads. Everything runs locally in your browser — nothing is uploaded, nothing is sent to any server, and closing the tab erases it all.

Online Metronome for Guitar Practice

Guitarists get more out of a metronome than almost any other instrument because both hands need locking together. Start by setting the tempo 20 percent below your target speed — if the song is 120 BPM, practice it at 96 until every note is clean, then raise the tempo by about 10 percent at a time and only move up when you can play the passage three times in a row without a stumble. Use the metronome above for alternating-picking drills at 60 BPM with eighth notes, accent drills where you strum harder on beat one, and scale runs grouped in fours. The online stopwatch is handy for timing 10-minute blocks per exercise so practice sessions stay honest.

Metronome With Sound & Time Signatures (4/4, 3/4, 6/8)

A good practice metronome does more than tick evenly — it accents the first beat of each bar so you always know where you are. In 4/4, four clicks per bar with the accent on one; in 3/4 (waltzes, ballads), three clicks per bar; in 6/8, two heavier pulses each covering three subdivisions. Practicing with the accent on is how you internalize a time signature instead of counting it. If the default click is hard to hear over an acoustic guitar, raise the volume or switch sound — a woodblock-style tone cuts through better than a beep. Drum-machine feel starts to appear once you add subdivisions: set the same tempo but listen for the half-beat and you are effectively practicing with a hi-hat.

How to Use a Metronome Properly (the 6-step routine)

  1. Set a tempo you can actually play at — the speed where mistakes are rare, not the speed of the recording.
  2. Clap or tap the rhythm first before adding the instrument, so the click and your body sync before technique gets involved.
  3. Play one short passage — two or four bars, not the whole song. Metronome practice works in small loops.
  4. Raise the tempo ~10 percent only after three clean passes in a row. Jumping faster is how habits fall apart.
  5. Practice landing, not racing — if you consistently rush, the problem is usually anticipation, so subdivide: hear the half-beat.
  6. Finish at a slower tempo than you started — ending with two relaxed, perfect passes teaches your hands the right last impression.

This routine pairs well with the countdown timer for structured blocks and the pomodoro timer for full 25-minute practice sessions. Teachers running group lessons can project the classroom stopwatch on a shared screen between rounds.

FAQ

Why does the first beat sound higher?
That is the accent — 1050 Hz vs 750 Hz — the standard way musicians hear where the measure begins.
How accurate is it?
Clicks are scheduled with the look-ahead technique against the AudioContext clock: sample-accurate, immune to setInterval jitter.
How does tap tempo work?
It averages your last four tap intervals and converts to BPM — tap in the feel of the music, not on notes.
What is 6/8 here?
Six eighth-note pulses per measure — set the slider to the eighth-note speed you feel.
Does it need internet?
No — after the page loads, everything is synthesized on your device.
What BPM should a beginner set a metronome to?
Start between 60 and 80 BPM for anything new — slow enough that every finger movement is deliberate, fast enough to keep musical momentum. Beginners often set tempos they cannot actually play yet; if you miss more than one note in four passes, drop the tempo by 20 percent and rebuild. Accuracy at slow speeds moves you up faster than repetition at fast ones.
Do professional musicians still practice with a metronome?
Constantly — session players, classical professionals, and drummers run metronome drills their entire careers. Pros use it differently though: instead of playing whole songs, they loop small passages at the edge of their ability and push the tempo up in small steps. A free online metronome with accents and subdivisions covers about 90 percent of what expensive practice apps do.
