Tune your ukulele with your phone or computer microphone. The tuner detects which string you play and shows how far to turn the peg. Standard (gCEA), low G, D tuning and baritone.

|---|---|---|
| 4. | G4 | 392.0 Hz |
| 3. | C4 | 261.6 Hz |
| 2. | E4 | 329.6 Hz |

How to tune
- Press “Start tuning” and allow the microphone. The sound stays in your browser and is never uploaded.
- Standard ukulele tuning is re-entrant: the top (4th) string is a high g, so the G string sounds higher than the C.
- New nylon strings stretch for days, so retune before every practice in the first week.
- Always tune up to the note from below. That way the peg doesn't slip back.
- When the needle sits in the green middle zone (±3 cents), the string is in tune. Anything within 5 cents sounds in tune to the ear.

Frequently asked questions
What is standard ukulele tuning?
From the top string down: g – C – E – A (G4, C4, E4, A4). The g string is higher than the C. This is called re-entrant tuning.
What's the difference between high G and low G?
With low G the 4th string is tuned an octave lower, to G3. It sounds fuller and more guitar-like, and you can play melodies lower down. You need a thicker, usually wound, G string for it.
Does it work for baritone ukulele?
Yes. Choose Baritone (D G B E), which matches the top four strings of a guitar.
