Free Online Guitar Tuner

How to Use the Guitar Tuner

This free online tuner uses your device's microphone to detect the pitch of your instrument and help you tune accurately.

• Click "Start Tuner" and allow microphone access when prompted
• Play a single note on your instrument
• The tuner will detect the note and show how many cents sharp or flat you are
• Adjust your tuning until the marker is centered (green = in tune)
• Use the preset buttons to see reference frequencies for standard guitar tuning

Chromatic vs. Standard Tuner

This is a chromatic tuner, meaning it can detect all 12 notes of the chromatic scale. This makes it perfect for:

• Bass - 4-string, 5-string, or 6-string bass
• Ukulele - Soprano, concert, tenor, or baritone
