Tuning Your Violin
To tune your violin using this online tuner, here's how:
- With this tuner, click start
- Click on "allow dacapoalcoda.com to use your microphone".
- Choose the reference A (440Hz, or generally 442Hz)
- Play the string you want to tune with the bow
- Check the accuracy of the tuning:

The slider is in the middle: you're perfectly in tune!

The slider is on the left: you're too low, you need to tighten the string by tightening or loosening the pegs or using the fine tuners on the tailpiece.

The slider is on the right: you're too high, you need to loosen the string by loosening or tightening the pegs or using the fine tuners on the tailpiece.
You'll need to tune the four strings, G, D, A, and E:
Before rehearsals, all string instruments in the orchestra tune to an A because they all have an open string that produces an A. Therefore, it's preferable to start with the A string of the violin even if you're playing alone:

Tune the A string (A4), by tightening or loosening the pegs or using the fine tuners on the tailpiece. The A string should turn purple (on the tuner, not on the violin, otherwise it might catch fire )

Tune the E string (E5), with the pegs or with the tailpiece. The E string should turn purple.

Tune the D string (D4), with the pegs or with the tailpiece. The D string should turn purple.

Tune the G string (G3), with the pegs or with the tailpiece. The G string should turn purple.
After tuning each string individually, briefly recheck the tuning of all four violin strings.
Some Tips
- New strings quickly detune; after changing a string, it needs more frequent tuning.
- If the strings don't hold their tuning, perhaps the pegs are poorly adjusted.
- Avoid over-tensioning while tuning, as from a tone and a half higher, there's a risk of breaking the string.
