How to tune a ukulele
- Press Start Tuning and allow microphone access when your browser asks.
- Play one note. Pluck a single string or play one key, close to the microphone, and let it ring.
- Read the display. The big letter is the nearest note. The bar shows how far off you are: left is flat (tune up), right is sharp (tune down).
- Turn until it goes green. Inside your tolerance (±3 cents by default) the display turns green and the string gets a check mark.
Tips
- Nylon strings stretch a lot. Expect to retune several times in the first week after restringing.
- Use the “My Dog Has Fleas” rhythm (G C E A) to check your ears after tuning.
- If you play a low-G set, choose “Low G” so the tuner targets G3 instead of G4.
