Ukulele C-Tuning Tuning

The reference tuning for the ukulele: G C E A, low to high.

How to tune

Getting into C-Tuning

Work down the list in order — each string's tension moves the ones already set.

  1. Allow microphone access

    Asked once. Detection runs on your device; nothing is uploaded.

  2. Play one string at a time

    Let it ring open. A strummed chord gives the detector several pitches.

  3. Centre the needle

    Sharp means loosen, flat means tighten. Inside three cents is in tune.

  4. Work up from string 4, one at a time

    The lowest string carries the most tension, so setting it first means the rest hold. The panel below lists every target in that order.

  5. Run through every string once more

    Setting one string drifts the rest; the second pass makes it hold.
