Chromatic Tuner for Guitar and Other Instruments

Looking for a fast and easy way to tune your guitar? You've come to the right place! Our free online tuner works through your device's microphone, perfect for both acoustic and electric guitars. But that's not all — this versatile tuner can also help you tune other instruments!

How to Tune Your Guitar

1. Press the “TURN ON” button below the tuner.
2. Allow your device to use the microphone for recording.
3. Play any string — the chromatic tuner will identify the note and show how accurate it is.
4. Adjust the tuning peg until the tuner shows the note is in tune — it turns green.

Custom Frequencies and Tuning Quality

Our tuner uses 440 Hz as the standard frequency for tuning, but you can select a different frequency if needed to match your preferences or specific tuning requirements. The tuner precisely analyzes sound frequency for each string. Remember, external noise and microphone quality can affect accuracy.

How Often to Tune

Frequent tuning is essential due to factors like playing time, temperature changes, and humidity. Typically, 1 hour of continuous play necessitates a tune-up. Even with less frequent playing, weekly tuning is recommended.
