What tempo range does the metronome support?

Anything from 20 to 300 beats per minute, set either with the slider or by typing an exact BPM value.

Why does the first beat sound different?

The downbeat of each bar is accented with a higher-pitched, louder click so you can feel where each bar starts based on the time signature you choose.

What do BPM tempo markings like Andante and Allegro mean?

They are traditional Italian tempo terms. Roughly, Largo is 40–60 BPM, Andante 76–108, Moderato 108–120, Allegro 120–168 and Presto 168–200. Set the slider to match the marking on your sheet music.

How should I use a metronome to get faster?

Practise a passage cleanly at a comfortable BPM, then raise the tempo by 4–8 BPM only once you can play it without mistakes. Repeating this gradually trains accuracy before speed.

Does the metronome need an internet connection or send audio anywhere?

No. The clicks are generated locally with the browser's Web Audio API. No audio files are downloaded and nothing is ever uploaded.

Online Metronome — Gera Tools

Keep steady time while you practise with this online metronome. Set any tempo from 20 to 300 BPM using the slider or by typing an exact value, then pick a time signature so the downbeat of each bar is accented. It works for any instrument and needs no app — useful for building tempo control, practising scales, or rehearsing tricky passages slowly before speeding up.

How it works

The metronome converts your tempo into a beat interval of 60000 ÷ BPM milliseconds and fires a click on each beat. The clicks are synthesised live with the browser’s Web Audio API: a short oscillator burst, pitched at 1500 Hz and louder for the accented first beat of each bar and 900 Hz for the other beats. A counter tracks the current beat within the bar (based on your chosen beats-per-bar) so the downbeat lands correctly, and a row of dots highlights it visually.

Example

You are practising a piece in 4/4 marked Allegro. Set the tempo to 120 BPM and beats per bar to 4, then press Start:

Beat interval = 60000 ÷ 120 = 500 ms between clicks
Every 4th click (the bar’s first beat) is the accented 1500 Hz tone
The dot row lights 1-2-3-4 in time, so you can both hear and see beat one

Tempo term	Typical BPM
Largo	40–60
Andante	76–108
Moderato	108–120
Allegro	120–168
