Guitar Tuner

A tuner is a device that detects a note’s pitch when played on a musical instrument, and compares it to the desired pitch. The tuner indicates whether the note is too high, too low, or in tune, helping musicians tune their instruments easily.

It's most common to use a tuner for string instruments such as guitars and violins. Over time, the strings loosen, and the instruments need to be tuned to maintain optimal sound. Most tuners are “chromatic tuners” and detect all 12 distinct notes.

To tune your instrument, click the red microphone button. You will be asked to allow access to your device’s microphone so the tuner can hear what you play. As you play a note on your instrument, adjust the pitch until the tuner indicates the note is in tune.
