To tune your guitar, search Google for “google guitar tuner”. In the applet that appears, tap or click the microphone icon to grant mic permissions, then play each guitar string you want to tune, adjusting it until Google shows you’ve achieved the correct note.

Need to tune your guitar? Tuner apps can be expensive, and forgetting your physical tuner at home is the last thing you need when you’re about to start a gig. The free Google Guitar Tuner is a search away in your browser and can work well in a pinch.

How to Find Google Guitar Tuner

To access the Google tuner, start by opening your browser. We tested using both Safari and Chrome. Navigate to the Google search page, type google guitar tuner into the search bar, and click or tap the search button. This applet should appear at the top of the search results.

In our testing, simply typing “guitar tuner” did not invoke the applet. This is different from other applets, such as the Google Calculator, which will appear at the top of search results even if you only search for “calculator.”

How to Use Google Tuner

Before using Google Guitar Tuner, you’ll have to give the website microphone permissions.  You’ll see the message “Press Mic to Begin Tuning.” Tap or click on the microphone icon.

You should see a popup asking for permission to use your microphone. Select “Allow” to proceed.

You should now see a message in the Google tuner that says “Listening,” which means the app is ready to help you tune your guitar.

Play the open string you want to choose, and the tuner will show what note it’s currently tuned to. In this case, we’re tuning the low E string (in EADGBE standard tuning), and the Google Guitar Tuner shows we’re a little off from there. If you’re using overdrive or distortion, turn it off for better results.

Tune the string higher or lower as needed until the tuner shows you’re on the right note with a green arrow.

Keep in mind that the Google tuner is a chromatic tuner. In other words, it will tune to any note in Western music notation. At the time of writing, there’s no option to set it to specific guitar tunings, so you’ll have to know which note you want to tune and whether it’s higher or lower than the currently displayed note.

How Accurate Is Google Guitar Tuner?

You may wonder if you can trust the Google tuner to tune accurately. In practice, the microphone quality in your device might affect how accurate the tuner app is. But since it’s listening for a simple frequency, it should work correctly on just about any device.

We used Google Tuner alongside the popular GuitarTuna app, the built-in tuner in an acoustic guitar, and an integrated tuner in a multi-effects pedal. They all returned precisely the same result as Google’s tuner applet, so we’re confident it will work well enough for all but the most discerning musicians.


Once you’ve got your guitar in tune, why not put the word “metronome” into Google for their metronome applet? It’s the perfect tool to practice your scales, and like Google Guitar Tuner, it’s entirely free to use.
