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.

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.

Worked example: 4/4 at Allegro

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 reference table

Italian term	Typical BPM range	Character
Largo	40–60	Very slow, broad
Adagio	56–76	Slow and stately
Andante	76–108	Walking pace
Moderato	108–120	Moderate
Allegro	120–168	Fast, lively
Vivace	156–176	Vivacious, quick
Presto	168–200	Very fast
Prestissimo	200+	As fast as possible

These ranges overlap and the boundaries are not strict — composers use them as mood directions more than precise tempo commands. When the score gives a BPM marking (for example ♩ = 132), set the slider to that exact value.

How to use a metronome to build speed correctly

The most common metronome mistake is starting too fast. The effective method:

Set the tempo slow enough that you can play the passage perfectly — not 95% correct, but error-free.
Record which BPM that is.
Raise by 4–8 BPM only after you have played it cleanly three times in a row.
When you make a mistake, drop back 4–8 BPM and re-establish clean playing before advancing again.

This process is slow at first and fast in the long run. Practising with mistakes at high tempo ingrains the errors; practising clean at lower tempo ingrains the correct motor pattern, and speed follows naturally.

Common time signatures and when to use them

Time signature	Beats per bar	Typical genre
4/4	4	Most pop, rock, classical
3/4	3	Waltz, many ballads
6/8	6 (or felt as 2)	Folk, compound feel
2/4	2	March, polka
5/4	5	Jazz, prog (Take Five)

For 6/8 at faster tempos, musicians often set the metronome to 2 beats per bar and count the six eighth-notes internally — the accented click marks the start of each group of three. Everything is synthesised in your browser — no samples to download and nothing uploaded.
