Ukulele Tuner
Tune your ukulele by ear with reference tones for G, C, E and A. Tap a string to hear its note, then match it — free, no app needed.
Tap a string to hear its reference tone, then tune your string to match it. The G string is re-entrant: it is tuned high, not low.
How to tune by ear
Tune the A string first (it is the easiest to hear), then match the others to it. Play the reference tone, then pluck your string: if yours sounds lower, tighten the peg; if higher, loosen it. When the beating sound disappears, the string is in tune.
| String | Note | Frequency |
|---|---|---|
| 4th string — G (re-entrant, high) | G4 | 392.00 Hz |
| 3rd string — C | C4 | 261.63 Hz |
| 2nd string — E | E4 | 329.63 Hz |
| 1st string — A | A4 | 440.00 Hz |
How it works: Standard ukulele tuning is G4–C4–E4–A4. The G string is re-entrant — tuned to G4, higher than the C string — which gives the ukulele its bright, close-voiced sound.
