About This Tool
Introduction
A metronome online is the simplest way to tighten your timing — and Trencada's free Online Metronome gives you a precise, drift-free beat for guitar, piano, drums, and any instrument, with no app to install and no account to create. Set any tempo from 30 to 300 BPM, tap in the beat with Tap Tempo, choose 2/4, 3/4, 4/4, or 6/8 time, and follow the accented downbeat with the visual beat dots. The clicks are synthesized live with the Web Audio API using a lookahead scheduler, so timing stays rock-solid even if your browser gets busy. Everything happens in your browser — no audio is recorded or uploaded.
How to Use
- Set your tempo: drag the BPM slider, use the − / + steppers, or tap Tap Tempo in rhythm with your song.
- Choose a time signature — 2/4, 3/4, 4/4, or 6/8.
- Press Start. The first beat of each bar plays at a higher pitch and flashes red (toggle Accent first beat off for uniform clicks).
- Adjust Volume so the click sits comfortably under your instrument, and follow the beat dots to stay locked in.
- Press Stop — all scheduled clicks are cancelled instantly for total silence.

Frequently Asked Questions (FAQ)
- How accurate is this metronome? Very. Instead of relying on basic timers (which drift), it uses the Web Audio API's high-precision clock with a lookahead scheduler — the same technique used by professional web-based music apps.
- Does it work on my phone? Yes. It runs in any modern mobile or desktop browser — Chrome, Edge, Firefox, or Safari. Keep the tab open and your ringer/volume up while practicing.
- Do I need to download or install anything? No. It's 100% web-based — just open the page and press Start.
- Is it really free? Yes. Every Trencada tool is free with no hidden fees or premium tiers.
- Is my playing recorded? No. The metronome only generates click sounds in your browser. It has no access to your microphone and uploads nothing.
