Free online tuner
Tune guitar, bass or ukulele with your device's microphone — or switch to chromatic for anything else. No sign-up, no download, and the sound never leaves your browser.
Guitar, bass, ukulele or chromatic
Standard, drop D, half step down and DADGAD guitar, four-string bass and ukulele — or chromatic mode for keys, voice, violin and anything else with a pitch.
Follows the string you play
Pluck any string and the tuner picks it. Tap a string to lock onto it when it is so far out that it sounds like its neighbour, and each string gets a mark once it is in tune.
Tune to the band, not just 440
Set the reference pitch anywhere from 430 to 450 Hz to match a piano, organ or backing track that sits slightly sharp or flat.
