About this ukulele tuner
A free online ukulele tuner that uses your microphone. It works for soprano, concert and tenor ukuleles, which share the same standard tuning, and you can set up other tunings with a custom tuning.
Standard ukulele tuning
The strings are G, C, E, A. Unlike a guitar, the G string is tuned higher than the C below it (this is called re-entrant tuning), so the lowest-pitched string is the C, not the G. That’s why the strings aren’t in order of pitch.
| Tuning | Strings |
|---|---|
| Ukulele · Standard (GCEA) | G C E A |
| Ukulele · Low G | G C E A |
| Ukulele · D tuning (ADF♯B) | A D F♯ B |
| Ukulele · Baritone (DGBE) | D G B E |
How to tune your ukulele
- Press “Start tuner” and allow microphone access.
- Pluck the G string (the one closest to your face when playing) and let it ring.
- Turn the peg until the needle sits in the middle and goes green.
- Repeat with C, E and A, then check each once more.
Tips
- Nylon and fluorocarbon strings stretch a lot when new, so expect to re-tune often for the first few days.
- Tune up to pitch: if you go past the note, loosen the string below it and tighten again.
- Ukuleles are quiet, so hold the phone close and tune in a quiet room.
- Pluck gently. A hard strum or pluck briefly makes the pitch go sharp.
FAQ
How do I tune a baritone ukulele?

How do I tune a low-G ukulele?

Why does my ukulele go out of tune so quickly?
New strings stretch, and temperature and humidity change the wood and the string tension. Re-tune whenever you pick it up.
