Online Metronome

Quarter-note positions: one 4/4 bar at 120 BPM

Start a metronome at your chosen BPM

Begin at 120 BPM in 4/4 and press Start metronome. The main control becomes Stop, so ending playback stays as easy as starting it. Use the large tempo controls or enter a value from 20 to 300 BPM. No sound starts just by opening this page.

BPM here always counts quarter notes per minute. At 120 BPM, a quarter note lasts half a second. A 4/4 bar has four of them, starting at 0, 0.5, 1 and 1.5 seconds; the next bar begins at 2 seconds. Unlike Tap Tempo, which estimates the pace of your taps, this tool supplies a continuing practice pulse.

Choose a meter and the spaces between clicks

Choose 2/4, 3/4, 4/4 or 6/8. Subdivisions split each numbered position into one, two or four evenly spaced clicks. The optional accent emphasizes only the first click of each bar. Numbers and a visual pulse help you follow your place; they do not grade your performance.

In 6/8 the six numbered positions are eighth-note clicks, grouped into two larger dotted-quarter pulses. At this tool’s 120 quarter-note BPM, those eighth notes are 0.25 seconds apart and a bar lasts 1.5 seconds. A marking of dotted-quarter equals 120 would be a different speed; this tool does not silently change the meaning of BPM when you choose 6/8.

While running, a valid tempo change takes effect at an upcoming numbered click and keeps your position in the bar. The screen distinguishes pending and applied BPM. A change made very close to a click may wait for the following one. Changing the other rhythm or practice settings stops playback so you can explicitly start the new setup.

Use a count-in, a short practice run or a click file

Optional count-in gives one or two bars before practice begins. Leave playback continuous, or choose an 8-, 16- or 32-bar practice run. The run length counts practice bars, separately from any count-in.

Download an eight-bar WAV when you need a finite click file for music software. The export follows the selected constant tempo, meter, subdivisions and accent; it excludes the count-in and practice-run limit. Live tempo changes are not recorded in the file. It is not a recording of your playing. Sound is synthesized in your browser without microphone access, an upload or signup. Playback stops when you leave or hide the page; visual display and speaker latency can differ between devices.
