Ukulele tuner
Tune a soprano, concert or tenor ukulele in standard GCEA tuning with your microphone. Pluck one string at a time and the needle shows whether it is flat or sharp; nothing is recorded.
–
Press Start, then play one string at a time.
The tuner listens through your microphone and needs JavaScript. The string notes and their frequencies are below, to tune by ear or with another tuner.
- G392.00 Hz
- C261.63 Hz
- E329.63 Hz
- A440.00 Hz
How to tune a ukulele with this tuner
- Press Start tuner and allow the microphone when your browser asks.
- Tune the A string first: play it on its own and watch the gauge.
- If the needle sits left of center, the string is flat: tighten it a little with the tuning peg. Right of center is sharp: loosen it.
- Stop when the needle stays in the green zone at the top, within 5 cents, and the readout says In tune.
- Tune the E, C and G strings the same way, then check the first one again: changing one string's tension can nudge the others.
The ukulele strings
| String | Note | Frequency |
|---|---|---|
| 1 | G4 | 392.00 Hz |

Strings are numbered here in the order they sit across the ukulele. Between neighbors: C is a perfect 5th below G; E is a major 3rd above C; A is a perfect 4th above E.
Soprano, concert, tenor and baritone
Soprano, concert and tenor ukuleles all use the same standard tuning, G C E A, with the G string tuned high. They differ in size and sound, not in their notes, so this tuner works for all three.
A baritone ukulele is different: it is tuned D G B E, like the four highest strings of a guitar. Some tenor players fit a low G string (G3) for a deeper bottom note; this tuner listens for the standard high G.
New strings stretch
Ukulele strings stretch for their first days, so a newly strung ukulele drifts flat again and again. Tune it, play, and tune it again; it settles as the strings stretch out.
If a string is sharp, bring it down below the note and tune up to it. A string tuned up to pitch holds its tuning better.
Tuning without a tuner
Once the A string is right, the frets give you the others, in this order: the G string at the 2nd fret matches the open A, the E string at the 3rd fret matches the open G and the C string at the 4th fret matches the open E. Pluck each pair one after the other and turn the peg until they sound the same.
Questions
What are the ukulele strings tuned to?
G4 (392.00 Hz), C4 (261.63 Hz), E4 (329.63 Hz) and A4 (440.00 Hz), in the order they sit from the top string to the bottom when you hold the ukulele.
Why is the G string higher than the C string?
Standard ukulele tuning is re-entrant: the G string is tuned to the G above middle C rather than the one below, so the top string is the second highest. Some players fit a low G string (G3) instead; this tuner is set for the standard high G.
Does this work for a baritone ukulele?
Not as set: a baritone ukulele is tuned D G B E, like the top four strings of a guitar. This tuner listens for G, C, E and A.
How do I tune a ukulele without a tuner?
Tune the A string to a reference note first. Then work down, tuning each string until it matches: the G string at the 2nd fret matches the open A, the E string at the 3rd fret matches the open G and the C string at the 4th fret matches the open E.
Does the tuner record me?
No. Your browser passes the microphone signal to this page, which measures the pitch and throws the sound away. Nothing is saved or sent.
