How to tune a viola online

Press "Tap to tune" and allow microphone access. Bow one open string with a steady stroke and let the pitch settle. The tuner shows the note and whether you are flat or sharp. Make small adjustments with the fine tuner or peg, then bow again to confirm. Tune all four strings, then repeat once more.

Standard viola tuning and target notes

The standard viola tuning is C G D A from low to high. Use the note list as your target and bow one string at a time for a clear reading.

Tips for tuning your viola

Tune in a quiet room and bow each string with a steady, even stroke. Use fine tuners for small adjustments. After tuning all four strings, do a second pass because adjusting one string can affect the others.
