Violin tuner
Tune your violin in the browser. The tuner recognizes the G, D, A and E strings, and you can match by ear with the reference tone. It switches to viola, cello and double bass too.
- Free, no limits

String notes: Violin (G D A E)
At A = 440 Hz. The tuner measures each plucked string against these frequencies.
| String | Note | Frequency |
|---|---|---|
| 4. | G3 | 196.0 Hz |
| 3. | D4 | 293.7 Hz |
| 2. | A4 | 440.0 Hz |
| 1. | E5 | 659.3 Hz |
How to tune
- Press “Start tuning” and allow the microphone. The sound stays in your browser and is never uploaded.
- Tune the A string first (440 Hz), then the others to it. That's how orchestras do it.
- For small adjustments use the fine tuners, not the pegs. Pegs can easily overshoot.
- Draw a long, even bow stroke. Pizzicato works too, but the note fades faster.
- When the needle sits in the green middle zone (±3 cents), the string is in tune. Anything within 5 cents sounds in tune to the ear.

Frequently asked questions
What are the violin string notes?
Low to high: G – D – A – E (G3 196 Hz, D4 293.7 Hz, A4 440 Hz, E5 659.3 Hz). Adjacent strings are a perfect fifth apart.
Why do orchestras tune to A?
Violins and violas both have an A string, and the oboe can hold an A very steadily. So everyone tunes to the oboe's A.
What if my orchestra tunes to 442 Hz?
Set the reference to 442 Hz and the tuner adjusts every string to it.
