Free Online Metronome

How to use

• Set tempo with the slider, the + / − step buttons, or Tap (tap at least twice and the BPM locks to the average interval).
• Pick a time signature and subdivision (quarter, eighth, sixteenth, or triplets).
• Hit Play. The dots above the controls flash in sync; the first beat of each bar is accented.

Why timing is the skill that carries everything

Most players who feel stuck are not held back by their hands — they are held back by their time. You can play every note correctly and still sound shaky if those notes land a hair early or late, and you can play very simple parts and sound professional if your time is dead solid. A metronome is the single most honest practice tool there is, because it does not flatter you: when you drift, you hear the click move against you. Practicing with one trains the internal clock that lets you lock in with a drummer, sit in a pocket, and record without a part wandering. The goal is not to depend on the click forever; it is to internalise steady time so thoroughly that you carry it with you when the click is gone.

A good metronome needs to be more than a beep. The accent on beat one tells you where the bar starts, so you always know your place in the measure. Subdivisions let you hear the smaller pulse between the main beats, which is where most timing errors actually hide. And a precise clock matters: this metronome is scheduled against the Web Audio buffer rather than the browser's general timer, so the click does not jitter or drift even on a busy page.

Accents, time signatures, and subdivisions

The time signature sets how many beats fall in a bar and which beat is accented. In 4/4 you get a strong beat one and three softer beats; in 3/4 you get the lilt of a waltz; odd meters like 5/4 and 7/8 group the pulse unevenly, and hearing the accent is the only reliable way to keep your place in them.

Subdivisions are the secret weapon. Set the click to play eighth or sixteenth notes and you are no longer guessing where the "and" of the beat lands — you can hear it. When you are learning a tricky passage, turn subdivisions on so every small note has a click to lean on; once the part is solid, drop back to quarter notes and let your own sense of the subdivision hold it together. That transition, from supported to unsupported, is exactly how loose timing becomes tight timing.

Practice modes

• Speed Builder — increases tempo by a set amount every few bars. The classic way to take a passage from slow-and-clean to performance speed without ever practicing it sloppily. Start slow enough to play it perfectly, and let the metronome ratchet the tempo for you.
• Fade Out — alternates bars of click with bars of silence. The click drops out, you hold the time on your own, and when it returns you find out immediately whether you rushed or dragged. This is the drill that actually builds your internal clock.
• Random Mute — silences roughly a third of the beats at random. It stops you from leaning on every single click and forces you to feel the pulse between the ones you hear.

How to practice with it

The cardinal rule is to practice at a tempo where you can play perfectly, not at the tempo you wish you could play. Speed is a by-product of accuracy, never the other way round. If you cannot play a passage cleanly three times in a row at the current tempo, do not push faster — stay there, or step back 5 BPM and rebuild. Mistakes repeated at speed only teach your hands to make the mistake faster.

Use eighth- or sixteenth-note subdivisions while you are learning a part, then drop back to quarters once your time is solid. When a passage feels comfortable, switch to Fade Out or Random Mute to test whether your time is genuinely internal or just borrowed from the click. When you measured a song's tempo elsewhere, the tap-tempo tool can hand the BPM straight to this metronome so you can practice along at the real speed.

Tips

• If you cannot play a passage cleanly three times in a row at the current tempo, do not push speed — stay, or step back 5 BPM.
• Use eighth-note or sixteenth-note subdivisions when learning a part, then drop back to quarters once your time is solid.
• Tap the click with your foot, not just your hands. Time that lives in your whole body is steadier than time you hold only in your fingers.
