Ukuleles are wonderfully approachable instruments, and tuning them is simpler than tuning a guitar since there are only four strings. Once you learn the basics, you’ll be in tune and ready to play in just a minute or two.
Most modern ukuleles use G-C-E-A tuning (from the thickest string to the thinnest). This is the universal standard you should assume when learning new songs or chord sheets. If someone doesn’t specify tuning, they mean G-C-E-A.
Interestingly, the high G string is actually tuned higher than the C and E strings, creating a unique ringing sound that’s characteristic of the ukulele. This is one reason the ukulele sounds so distinct and cheerful.
You have several good options:
Step 1: Get a reference tone for the first string. Use your chosen method to identify what pitch the G string should be.
Step 2: Pluck and adjust the G string. This is typically the thickest string (though some ukuleles have different string gauges). Adjust the tuning peg until it matches your reference tone. If you’re tuning sharp (too high), turn the peg away from you. If you’re tuning flat (too low), turn it toward you. Check your specific uke—the direction varies by model.
Step 3: Tune the C string. Move to the next string. This string should be noticeably lower than the G string. Adjust until it matches the C note.
Step 4: Tune the E string. The third string should be tuned to E, which is higher than the C.
Step 5: Tune the A string. The highest string should be A, the highest pitch of the four.
Step 6: Double-check everything. Play through all four strings again to ensure they’re still in tune.
If you’re using a clip-on tuner:
This is the quickest, most accurate method and perfect for beginners.

This works great as long as you have a quiet environment.
Once you’re comfortable with electronic tuning, you can develop your ear by tuning without a tuner. Start with one string you know is correct, then:
This is harder than it sounds at first, but it’s a valuable skill that develops quickly with practice.
New strings need time to settle. Freshly restrung ukuleles go out of tune frequently for the first few days. This is completely normal. Tune, play, and retune until they stabilize—usually takes about a week.
Tune gently. Ukulele tuning pegs aren’t as heavy-duty as guitar machines. Turn them smoothly and steadily to avoid damage.
Humidity affects tuning. Ukuleles are often made of wood, which responds to moisture in the air. Dry environments cause instruments to go flat; humid environments push them sharp. A humidifier helps maintain stability.
Tune before every session. Like any instrument, tune your uke before playing, even if it was in tune yesterday.
Tune up to the note when possible. If you overshoot and go sharp, come back down and approach from below. This helps the string hold tension better.
The high G string confuses me. Don’t worry—this is normal. The high G is intentional and creates that distinctive ukulele sound. Make sure you’re tuning the correct octave (higher, not lower).
My tuner keeps showing the wrong note. Chromatic tuners sometimes need to know which note you’re aiming for. Some tuners let you pre-select the note.
Tuning pegs keep slipping. Uke pegs sometimes need gentle tightening, or the strings might be worn. If it’s persistent, have a tech check it.
The strings feel wrong. New strings have different tension than old ones. Play for a day or two and retune—you’ll adjust to the new feel.
Once you’re comfortable with standard tuning, you might experiment with:
Low G tuning: Instead of high G, tune the G string lower (same pitch as the G on a guitar). This is popular for fingerpicking and gives a different character.
Dropped D tuning: D-A-D-G or C-G-D-A, depending on your approach. Opens up new chord possibilities.
Slack-key tunings: Hawaiian-influenced tunings that create unique atmospheres.
But start with standard G-C-E-A tuning—this is what the vast majority of ukulele music uses.
Consistency is key. Make tuning part of your picking-up-the-instrument routine:
After a couple of weeks, your fingers develop sensitivity to the right tuning peg resistance, and your ear becomes more aware of proper pitch. This knowledge transfers to any stringed instrument you pick up later.
Tuning is the first step to enjoying your ukulele. A properly tuned uke sounds bright, cheerful, and encouraging to play. Start with an electronic tuner to build confidence and develop accuracy, then gradually expand to tuning by ear as your skills grow. You’ll be amazed how quickly this becomes second nature.
