How to tune a ukulele
Hold your uke close
A ukulele is a quiet instrument, so pick a quiet room and keep the device near the body of the ukulele.
Start the tuner
Start the tuner and allow microphone access when your browser asks.
Tune the A string
Pluck the open 1st string, A, and let it ring. Turn its peg until the tuner shows the string is in tune.
Tune E, C and G
Tune the 2nd string (E), then the 3rd string (C), then the 4th string (G) the same way, one at a time.
Approach from below
Turn each peg slowly. If you overshoot, back off below the note and tighten up again; nylon strings hold better that way.
Check all four strings again
Nylon strings settle slowly, so one more pass over G, C, E and A makes sure none has crept flat.
Ukulele tuning: G C E A (standard)
Standard ukulele tuning is G, C, E, A, from the 4th string to the 1st. The 4th string is a high G, tuned higher than the C string next to it, which gives the ukulele its bright, friendly sound. This is the standard tuning on soprano, concert and tenor ukuleles. The tuner also offers Low G (G C E A) and D tuning (A D F♯ B), which you can choose from the tunings menu.
Ukulele string notes
String 4 is G, string 3 is C, string 2 is E and string 1 is A. String 1 is the thinnest, closest to the floor when you hold the ukulele, and string 4 is the one closest to your face.
Tips for keeping your ukulele in tune
Check every time you pick it up
Ukulele strings drift flat quickly, even between songs. A quick check before you play keeps your chords clean.
New strings need patience
New ukulele strings stretch a lot at first. Expect to retune several times a day for the first few days.
Pluck gently
The strings are soft, so pluck with a medium touch. Hitting them hard makes the pitch jump sharp for a moment.
Keep it away from heat
Heat, direct sun and dry air change the pitch and can damage the wood. Keep the ukulele in a case or in a room with a steady temperature.
Ukulele tuner FAQ
A ukulele has four strings. In standard tuning they are G, C, E and A, from the 4th string to the 1st. The G is a high G, higher than the C string beside it.
Press start, allow the microphone and pluck the open A string. If the tuner reads flat, tighten the peg a little; if it reads sharp, loosen it. Repeat for E, C and G.
You need one reference note. You can play the reference tones on this page, or use an A from a piano or a tuning fork. Tune the A string to it. Then press the 5th fret of the E string and tune the E until it matches the open A. Press the 4th fret of the C string and tune the C until it matches the open E. Finally, press the 7th fret of the C string and tune the G until it matches that note.
The correct spelling is ukulele, a Hawaiian word. Many people write ukelele or uke, and this tuner works the same whichever spelling you use.
No. Soprano, concert and tenor ukuleles all use G, C, E, A. A baritone ukulele is different. It is tuned D, G, B, E, like the top four strings of a guitar, so it needs different notes than the standard tuning on this page.
Yes, in a quiet room. A ukulele is a quiet instrument, so hold your device close to it and pluck each string clearly. Close doors and windows if you can, because a noisy room makes the reading jump.
