Play one string — Hz
Signal

Allow microphone access, then pluck a string cleanly near the 12th fret.

Standard tuning

Choose a string

Auto detects any chromatic note. Choose a string to measure against its exact standard pitch.

How to get the cleanest reading

Use the neck pickup, mute the other strings, and pluck once with a steady attack. Keep the microphone close enough for a healthy signal without clipping.

For a webcam microphone, start the tuner first, then select the webcam by name from Audio input. Browsers reveal device names only after permission is granted.
