Online vocal tuner
A live singing pitch monitor: sing and watch your voice drawn on a piano roll in real time, with the note you're on labelled as you go. No install, no account — and your microphone audio stays on your device.
What it does
The tuner listens to your microphone and detects your pitch many times a second, drawing it as a continuous line against a piano-roll grid. Unlike a guitar tuner's single needle, you see the shape of what you sing — steady notes, slides, wobble and drift — which makes it a fast way to spot and fix intonation problems.
How to use it
- Open the tuner and allow microphone access.
- Sing a steady note. Aim to keep the line flat and centered on a grid line — that's an in-tune, stable pitch.
- Try a slide or a scale. Watch the line climb note to note; smooth, even steps mean clean intonation.
- Check problem notes. Sing a phrase you struggle with and see exactly where the line drifts flat or sharp.
Pitch is detected in your browser. Your microphone audio is never uploaded — nothing leaves your device. Use headphones in a quiet room for the cleanest reading.
Tuner vs. guided practice
A free-form tuner is perfect for exploring and checking. When you want to improve on purpose, switch to guided drills: they add target notes to aim at and score every run so you can track progress. Start with singing in tune, or map your vocal range first so exercises fit your voice.
Frequently asked
Is it really free?
Yes — no install, no account. Open it and sing.
What do I need?
A modern browser and a microphone. Headphones and a quiet room improve accuracy.
Why does the line jump or disappear?
Background noise, very quiet or breathy notes, and consonants can confuse any pitch detector. Sing a clear, sustained vowel for the steadiest line.
