How to use the online metronome

Set a tempo with the big BPM readout, choose a time signature and a subdivision, then press Start or the Space bar. The first beat of each bar is accented, and you can click any beat to accent it, play it normally or mute it. Your settings are remembered on this device for next time.

  1. 第 1 步

    Set the tempo

    Drag or scroll the BPM number, use the + and − buttons, type a value, or tap the beat with the Tap button or the T key. The tempo marking, such as Andante or Allegro, updates as you go.

  2. 第 2 步

    Choose a meter and a subdivision

    Pick 2/4, 3/4, 4/4, 5/4, 6/8, 7/8, 9/8 or 12/8, or build a custom meter. Add eighths, triplets or sixteenths to hear the beat divided.

  3. 第 3 步

    Start and shape the pattern

    Press Start or Space. Click a beat to cycle it between accent, normal and mute, and switch on the speed trainer to raise the tempo every few bars.

C你能得到什么

What you get

  • F.01

    Clicks timed on the audio clock

    Every click is scheduled on the Web Audio clock a fraction of a second ahead, so the beat stays even while you scroll, type or open other tabs.

  • F.02

    Accent patterns you can click

    Each beat cycles between accent, normal and mute. Downbeats, other accents, plain beats and subdivisions each get their own pitch and level.

  • F.03

    Subdivisions and odd meters

    Eighths, triplets and sixteenths over any meter from 1 to 16 beats, including 5/4, 7/8 and 12/8 with sensible default groupings.

  • F.04

    Speed trainer

    Raise (or lower) the tempo by a set number of BPM every few bars until you reach a target. Changes land exactly on a bar line.

  • F.05

    Tap tempo and keyboard control

    Tap the beat with the T key to set the tempo. Space starts and stops, the arrow keys nudge by 1 BPM, Shift plus an arrow by 10.

  • F.06

    Three sounds, readable at a glance

    Choose a click, a woodblock-style tone or a beep. Large beat lights and a moving playhead show where you are in the bar.

D谁在用

Who uses an online metronome

  • Students and teachers

    Practice scales, etudes and pieces at a marked tempo, then raise it in small steps. Teachers can share a link such as /metronome?bpm=72 so a student starts at the right speed.

  • Drummers and bass players

    Lock in with accents on the backbeat, mute beats to test your internal clock, and use sixteenths or triplets to tighten fills and shuffles.

  • Singers and songwriters

    Keep a steady pulse while you write or rehearse. Find the tempo of a song with Tap Tempo, then practice with the click at that speed.

  • Producers and bands

    Check a song’s tempo before a session, rehearse to a click before tracking, or count in a band at the same BPM as your DAW project.

E准确度与限制

How steady is it?

Each click is placed on the Web Audio clock ahead of time, not fired from a JavaScript timer, so the spacing between clicks doesn’t wander when the page is busy. What can vary is when you hear the sound: Bluetooth audio, for example, adds a constant delay, but the beat itself stays even.

实测准确率:上线时公布。我们怎么测 →
素材效果预期表现
Click timing (scheduled on the audio clock)很好Click times are computed from the start time, not added up beat by beat, so long sessions don’t drift.
Background tab or minimized window良好Keeps playing. Browsers slow page timers in the background, so the scheduler queues clicks further ahead.
Changing tempo while it plays良好The next click follows the new tempo. Clicks already queued, usually a tenth of a second, play first.
Visual beat lights良好Synced to the audio output clock. Screens redraw in steps, so a light can trail the sound by a frame.
Bluetooth headphones and speakers一般Add a fixed delay. The beat stays even, but you hear it later than the lights. Wired headphones avoid this.
Heavily loaded or low-power devices一般Any browser audio can glitch under heavy load. Close demanding tabs if you hear gaps.

Tips for practicing with a metronome

A metronome helps most when you use it on purpose, not as background noise.

  1. Start slower than you think. Pick a tempo where you can play the passage cleanly three times in a row, then raise it.
  2. Raise the tempo in small steps, around 2 to 5 BPM, and stay at each step until it feels relaxed.
  3. Use subdivisions for slow tempos. At 50 BPM a lone quarter-note click leaves a long gap; eighths or sixteenths fill it in.
  4. Mute beats to test yourself. Leave only beat 1 sounding, or mute every other bar, and see if you still land on the click.
  5. Put the click on 2 and 4. Accent beats 2 and 4 and mute 1 and 3 to practice backbeat feel for jazz, funk and pop.
  6. In 6/8, feel two big beats per bar. Try the dotted-quarter pulse by setting 2/4 with triplets, or keep 6/8 and listen for the accents on 1 and 4.
  7. Record yourself with the click. Listening back shows whether you rush fills or drag long notes more clearly than playing does.
  8. Practice without the click too. The goal is a steady internal pulse; the metronome is a mirror, not a crutch.

How to practice with a metronome

A metronome does one job: it gives you a pulse that doesn’t speed up when the music gets exciting or slow down when it gets hard. Practicing with one shows you exactly where your own timing bends, which is the first step to fixing it.

The classic method is slow, clean, then gradually faster. Find a tempo where you can play a passage without mistakes and without tension. Play it a few times there, then raise the tempo by a few BPM. When you start to fumble, drop back to the last tempo that felt easy and build up again. The speed trainer on this page automates this: set a step, a number of bars and a target, and it raises the tempo on a bar line so you can keep playing.

Listen for where your notes land against the click. If the click disappears under your notes, you’re on it. If you hear the click just before your note, you’re dragging; just after, you’re rushing. Many players rush runs and drag long notes, so practice both.

Once you’re comfortable, make the metronome do less. Mute beats 2, 3 and 4 so only the downbeat sounds, or put the click on beats 2 and 4 only, the way jazz and funk musicians do. Fewer clicks means your own sense of time has to fill the gaps, and that’s what carries over to playing with other people.

Choosing a tempo: Italian markings and BPM

Many scores give a tempo in words rather than numbers. The table below lists the common Italian markings from slowest to fastest with typical BPM ranges. They are conventions, not rules: references disagree by a few BPM, ranges overlap, and the right tempo also depends on the style, the hall and the player. The slider on this page uses the ranges printed on a traditional mechanical metronome face.

Choosing a tempo: Italian markings and BPM
MarkingMeaningTypical BPM
Gravevery slow and solemnbelow 40
Largobroad, slow40–60
Larghettoa little less slow than largo60–66
Adagioslow, at ease66–76
Andanteat a walking pace76–108
Moderatomoderate108–120
Allegrettomoderately fast, lighter than allegroaround 100–128
Allegrofast and bright120–168
Vivacelivelyaround 156–176
Prestovery fast168–200
Prestissimoas fast as possible200 and above

If a score says “M.M. ♩ = 96”, M.M. stands for Maelzel’s Metronome, after the 19th-century device, and it means 96 quarter notes per minute. When a piece gives only a word, choose a tempo inside the range that lets the fastest notes stay clear, then adjust by ear.

For practice, the target tempo is only the destination. Start at roughly two-thirds to three-quarters of it, play cleanly, and climb. If a song’s tempo isn’t written down, tap along with a recording on Tap Tempo or drop the audio into BPM Finder to measure it.

Subdivisions, triplets and odd meters

Subdivisions split each beat into smaller, quieter clicks. Two per beat gives eighth notes in 4/4, three gives triplets, four gives sixteenths. They’re the most useful practice setting at slow tempos, where the gap between beats is long enough for your timing to drift, and for passages full of fast notes, where you need to hear exactly where each note belongs.

Time signatures with 8 on the bottom work differently from 3/4 or 4/4. In 6/8 there are six eighth notes per bar, but most music in 6/8 is felt in two big beats of three eighths each. That’s why this metronome accents beats 1 and 4 in 6/8, beats 1, 4 and 7 in 9/8, and 1, 4, 7 and 10 in 12/8. In these meters the BPM counts the eighth notes, so 6/8 at 180 BPM is the same speed as two dotted-quarter beats at 60.

Odd meters have uneven groups. 7/8 is commonly grouped 2+2+3, so the default pattern accents beats 1, 3 and 5. Pieces grouped 3+2+2 or 2+3+2 exist too: click the beats to move the accents until the pattern matches your music. 5/4 is often felt as 3+2; accent beat 4 if that helps.

If you’d rather count 6/8 as two beats, set the meter to 2/4 and choose triplets. You’ll hear the same rhythm, but the BPM now counts dotted quarters, which is how many scores in compound time mark their tempo.

Why browser metronomes drift, and how this one doesn’t

A simple web metronome plays a sound every time a JavaScript timer fires. Those timers aren’t precise: they can fire late when the page is busy, and browsers deliberately slow them down in background tabs. The result is a beat that wobbles, or stalls when you switch tabs.

This metronome uses the Web Audio clock instead, which runs on the audio hardware. A small scheduler wakes up every 25 milliseconds and books the next clicks on that clock, a tenth of a second ahead. Each click time is calculated from the moment you pressed Start, not added up beat by beat, so rounding errors can’t pile up over a long session. In a background tab the scheduler books clicks further ahead, so the beat carries on even when the browser slows its timers.

The beat lights and playhead follow the audio output clock, not a separate timer, so what you see matches what you hear. If you use Bluetooth headphones, the sound reaches your ears later than the lights; that delay is constant, so your practice timing isn’t affected, but wired headphones or speakers keep sound and picture together.

Set the tempo by dragging, scrolling or typing the BPM number, pick a time signature and subdivision, then press Start or the Space bar. Click any beat to cycle it between accent, normal and mute. The arrow keys change the tempo by 1 BPM, Shift with an arrow by 10, and T taps the tempo.

Start at a tempo where you can play the passage cleanly and relaxed, often two-thirds to three-quarters of the target speed. Play it correctly a few times, raise the metronome by 2 to 5 BPM, and repeat. If mistakes creep in, drop back to the last comfortable tempo. The speed trainer can raise the tempo for you.

Choose 6/8 under Time signature. The metronome clicks six eighth notes per bar and accents beats 1 and 4, so you feel two groups of three. Here the BPM counts eighth notes. If your score marks the tempo in dotted quarters, set 2/4 with triplets instead and enter that number as the BPM.

Yes. The clicks are scheduled on the browser’s audio clock, and when the tab is in the background the scheduler books them further ahead, because browsers slow down page timers there. You can switch to sheet music, a video or another app and the beat keeps playing until you press Stop.

Yes. Switch on Speed trainer, then set the step in BPM, how many bars to play at each tempo, and the target tempo. When you press Start, the metronome changes the tempo by that step on a bar line each time the bar count is reached, and stops changing once it hits the target.

Bluetooth audio is buffered before it plays, which adds a delay between the moment a sound is made and the moment you hear it. The clicks stay evenly spaced, so your practice timing is fine, but they arrive after the beat lights. Wired headphones or your device’s speakers keep sound and lights together.

Yes. The metronome is free, with no sign-up and no ads, and it runs entirely in your browser. Nothing is recorded or uploaded. Your tempo, meter, accents and sound are saved in this browser so they’re ready next time, and you can share a tempo with a link like /metronome?bpm=90.
