Tuner

Microphone tuner for every fretted and bowed instrument on the site, with popular alternate tunings — and an option to speak each detected note aloud for hands-free, eyes-free tuning. New to tuning? Start with how to tune your instrument.

Tuner

Pick an instrument and tuning, then play a string — the display shows the note, how far off you are, and which open string you're closest to. Prefer tuning by ear? Use the reference tone tool.

Instrument

Tuning

Start the microphone tuner and play a single open string.

Microphone audio is analyzed in your browser and never leaves your device.
