Free Online Guitar Tuner

Get your guitar perfectly in tune in seconds. The TronicalTune Online Guitar Tuner is a free, fast, and accurate tool that works directly in your browser. Using your device’s microphone, it provides instant feedback to help you tune your acoustic guitar, electric guitar, bass, ukulele, or banjo. No apps, no downloads, just perfect pitch.

How to Use Our Online Guitar Tuner

Tuning your instrument has never been easier. Just follow these simple steps:

1. Allow Microphone Access: When prompted by your browser, click “Allow” to give the tuner access to your device’s microphone. Our tuner is secure and only uses the mic for pitch detection.
2. Select Your Instrument & Tuning: Choose your instrument (6, 7, or 8-string guitar, banjo, etc.) and your desired tuning from the dropdown menus. For any note, select the Chromatic mode.
3. Play a String: Pluck a single string on your instrument. The tuner will display the note you are playing and show you how sharp (high) or flat (low) it is.
4. Adjust and Tune: Turn the tuning peg on your guitar to adjust the pitch. The needle on the tuner will move towards the center. When the needle is in the middle and the display turns green, the string is perfectly in tune.
5. Repeat for All Strings: Move on to the next string and repeat the process until your instrument is perfectly tuned.
