As far as actual, physical tuning devices go, there are a lot of micro-sized, clip-on tuners out there these days. They attach easily to your violin, pick up the vibrations from the violin strings, and then tell you which way you need to tune.

Sounds great, right? Here’s the downside – they all cost money. Some of the better violin tuners at the higher end of the range can go up to $100.

Here’s what truly IS great: our violin tuner app can be downloaded right to your smartphone – Android and iOS formats are supported – all for free! That’s right – you can have this incredible tuning tool at absolutely no cost to you!

Violin Tuning Basics

Stringed instruments such as the violin are tuned by applying the correct amount of tension to its strings, resulting in a pitch that is harmonically perfect. That in and of itself can be tricky enough, but you then have to tune each individual string to be correct relative to the others on your instrument. With our violin tuner app, you’ll find that this is a pretty painless process.

The first step to properly tune your violin is to download GuitarTuna app and go to the Settings section. There you’ll find a wide range of instruments that the app supports, but for our purposes the section you want to select is ‘Violin Family’. From there, simply pick ‘Violin: Standard’.

From there, you’re taken back to a screen that shows a violin headstock. In manual mode, all you have to do is press the note letter – this will generate an accurate tone that you can use to tune by ear. From there, you then turn the tuning peg on the headstock to get the string to match the note from the tuner. You’ll either be sharp (too much tension, giving you a higher pitch), or flat (too little tension, resulting in a pitch that’s too low). Once the notes sound the same, you’ve got it!

The Auto mode in our violin tuner is even easier to use. Here all you have to do is play a note – the algorithm will detect which note you are trying to tune to, and it will show an indicator above the image of the headstock. This will show you if you are sharp or flat, and it moves accurately as you adjust the string tension.

Once the string has the right amount of tension to be tuned to pitch, the indicator will land directly above the headstock image. Then you move to the other strings and repeat the same process.

That’s it! Once you’re done all of the strings your violin will be perfectly in tune, and ready for practicing or performing.
