How to Make Use of Our Free Online Violin Tuner

  1. Click ‘Start Tuner
  2. Allow your browser to access your microphone.
  3. Play the violin’s A string.
  4. Watch the needle on the tuner. If the needle points to the right, your tone is too high. If the needle points to the left, your note is too low.
  5. Use the fine tuners to make an adjustment to the violin string. Turn the fine tuner clockwise if the pitch is too low. Turn the fine tuner counter-clockwise if your note is too high.
  6. Repeat step 3 and 4 until the needle stays in the center (pointing to the middle).
    If your needle is on target, your violin is in tune!
  7. Continue through the DG, and E strings using Steps 3 through 5.
  8. Re-check the intonation of each string. If any string is out of tune, tune it again.

How to Tune Your Violin

Press the “Start Tuner” button on the tuner. Your device will ask for permission to record sound from a microphone – click allow recording. In that way, our free online tuner will have the opportunity to hear the sounds of your violin.

Play any string – the chromatic violin tuner will show what note it is, and how accurately it is tuned. If the tuner shows a deflection, use the fine tuners to make an adjustment to the violin string. Turn the fine tuner clockwise if the pitch is too low. Turn the fine tuner counter-clockwise if your note is too high.

As soon as the needle on the tuner points to the middle, your violin string is in tune!

Your task is to tune all the violin strings to the right notes. The notes for each string are shown in the note names under the tuner. You can click any of the note names to hear what the end result should sound like.

Violin tuning does not end here. After you have tuned all the strings in the following order: A, D, G, E,  we recommend checking their sound in the reverse order. The fact is that the total tension of the violin neck changes if the tension of an individual string is greatly changed. For example, if you tuned the first string, but the others were not very tight, then after setting up all the strings, the first one will be “below” the required level.

Using the Notes Under our Violin Tuner

The analysis of the frequency of sound will allow you to fine-tune each string. The tuning quality strongly depends on the frequency response of the microphone, from external noise. Especially for rare cases when there are problems with the microphone, the page contains the sounds of the strings for tuning by ear.

Violin Tuning Notes
To tune the violin by ear, follow the following steps:

  1. Have a look at the note names that are depicted under the tuner. Click on the note A
  2. Tune the A string to match the tuner sound
  3. Continue this process for the D, G and E string

Bookmark this site and tuning your violin will no longer be a problem for you. Have a good playing!

How often do you need to tune the violin

Violin requires periodic tuning. Active play, changes in ambient temperature, humidity, long-term storage – all this can cause the violin to go out of tune. As a rule of thumb, 1 hour of continuous play is enough to make it necessary to tune the violin. Even if you play a little, but have not tuned your violin for more than a week, most likely, it will require tuning.

I know, this is one of the best ones out there. I was thinking that it would cost money, but nope, its free!

This violin tuner is very good and I don’t need to always open the tuner that I bought in the Music Shop,It is very convenient to open this tuner app, also easy to search. Good comment from Cheryl Pang!
