Frequently Asked Questions

Is this metronome accurate enough for professional use?

Yes. We use the Web Audio API, which schedules sounds directly on the device hardware clock. This avoids the micro-delays typical of other web applications and guarantees millisecond precision, even during long sessions.

What is Tap Tempo and how do I use it?

It's a feature that lets you calculate BPM by tapping rhythmically. Just click the 'TAP' button or press the spacebar to the beat of the music you're listening to, and instantly get the exact tempo.

Can I change the time signature and accents?

Yes, you can configure different time signatures (2/4, 3/4, 4/4, 6/8, etc.) and customise the beat accents to match the style of music you are practising.

Why can't I hear anything on my iPhone or iPad?

On iOS devices, Web Audio technology respects the physical silent switch. Make sure your phone is not in silent mode and turn up the media volume to hear the clicks.

# Rhythmic Precision at Your Browser

Welcome to the Definitive Online Metronome. We built this tool with one goal in mind: reliability. Unlike other web metronomes that suffer from "drift" (small cumulative delays) due to processor load, our sound engine is built directly on the Web Audio API.This means that sound pulses are scheduled ahead of time on your device hardware clock, guaranteeing unbreakable millisecond precision, even if you minimise the tab or your computer is busy.

Clear Visualisation

Large, high-contrast visual indicators with a "ripple" effect. Designed to be perceived with your peripheral vision, letting you keep your eyes on your sheet music or instrument without losing the beat.

Smart Tap Tempo

Listening to a song and want to know its speed? Press the TAP button or the Space key along with the music. The algorithm will calculate the exact average of your taps.

# Master Guide: How to Practise with a Metronome

The metronome is not just a ticking clock; it is the most impartial judge of your technique. Here is a proven methodology to improve your speed and cleanliness:

# 1. The Ladder Method

If your goal is to play at 120 BPM, do not start trying at that speed. Getting frustrated is easy; progressing requires strategy.
  • Start at 50% of your target speed (e.g. 60 BPM).
  • Play the passage perfectly 3 times in a row. If you miss a note, the counter resets.
  • Raise the metronome by just 5 BPM.
  • Repeat until you reach your target speed.

# 2. Accent Displacement

Use our time signature selector to shift the accent. Practising a 4/4 passage with the metronome set to 3/4 means the accent (the sharp click) lands in different places within your phrasing, forcing you to internalise absolute time instead of relying on beat "one".

# 3. Strategic Silences

An advanced technique is to set the metronome at half speed (e.g. 60 BPM if you play at 120) and feel each click as beats 1 and 3. Even harder: feel it only as the off-beats. This builds your internal clock.

# Curious Facts about Tempo

Tempo radically affects the emotional perception of music.
Italian Term BPM Approx. Character
Largo40 – 60Slow and solemn
Andante76 – 108Walking pace, calm
Allegro120 – 156Fast, bright and joyful
Presto168 – 200Very fast, frantic

# Technology Behind This Metronome

This is not a looping MP3 player. We are generating pure sine waves in real time. The main oscillator creates a 1000 Hz tone for the accent and 800 Hz for the weak beats, with an ultra-short ADSR envelope for maximum punch. This ensures an instant sound attack.Whether you are a drummer locking in the groove, a pianist working on scales, or a guitarist perfecting a solo, this metronome is your silent partner (until you hit play).
