๐ต Metronome
A metronome with a free BPM and time signature setting. It supports tap tempo and classical tempo name presets (Largo, Allegro, etc.), making it useful for instrument practice or checking a band's tempo.
How to use
- Enter a BPM value, or adjust it with the slider.
- Choose a time signature (e.g. 4/4) and a sound.
- Click "Start" to begin the click track while you practice.
How the calculation works
This metronome clicks at a steady tempo (BPM, beats per minute) in the time signature you set. It covers 20โ300 BPM, with an accented sound on beat 1. Length of one beat (seconds) = 60 รท BPM Clicks are scheduled slightly ahead with the browserโs audio engine (the Web Audio API). Because the timing of the sound is set separately from drawing the screen, the rhythm stays steady even when the page is busy. In a background tab it schedules further ahead so beats do not drop out. Choose from six sounds and switch between a dot display and a pendulum. Press Tap along with a song to match its tempo.
Worked example
At 120 BPM One beat = 60 รท 120 = 0.5 s One bar of 4/4 = 0.5 s ร 4 = 2 s A way to practise Get a hard passage clean at 60 BPM, then raise the tempo 5โ10 BPM at a time towards a target of 120 BPM.
Things to be aware of
- For 6/8, either count six beats or count two dotted-quarter beats. At faster tempos, counting two feels more natural.
- Bluetooth earphones can add a noticeable delay. For ensemble or rhythm practice, wired earphones or speakers work better.
- On a phone, turning off the screen can pause the browser and stop the clicks.
