How to tune a violin
- Tap Use microphone and allow access when your browser asks.
- Start with the A string. Bow or pluck it and let it ring.
- Use the fine tuners on the tailpiece for small changes, and the pegs only if a string is well off.
- Tune D, G and E the same way, then check A again. Pegs can slip, so press them in gently as you turn.

Violin tuner questions
What are the violin string notes?
From the lowest string to the highest: G, D, A and E. The A is usually tuned to 440 Hz.
Should I use the pegs or the fine tuners?
Use the fine tuners for small adjustments. Only use the pegs when a string is more than a semitone out, and turn them in small movements while pressing inwards.
Can I bow instead of pluck?
Yes. A steady bow stroke gives the tuner a long, clear note, which often reads more steadily than a pluck.
Does it work on my phone?
Yes. It works in Safari on iPhone and Chrome on Android, as well as desktop browsers. Hold the phone close to the instrument and allow microphone access when asked.
Why can't the tuner hear me?
Usually the browser hasn't been given access to the microphone, or it is listening to a different input. The tuner will tell you which, and how to fix it. Play one string at a time, close to the device.
Is my audio recorded?
No. The sound is analysed on your own device in real time. Nothing is recorded, stored or uploaded.
