How to Tune a Beginner Ukulele (and Why It Sounds “Wrong” at First)
Tune a beginner soprano ukulele to standard GCEA reentrant tuning, and understand why it sounds different from a linear low-to-high tuning like a guitar's.
Never force a friction tuning peg tighter to try to make it hold pitch — over-tightening risks cracking the headstock. A friction peg that won't hold tuning needs adjustment (or replacement with a geared tuner), not more force.

Use a clip-on chromatic tuner (or a ukulele-specific tuning app) rather than tuning by ear at first — reentrant tuning is hard to learn by ear before you already know what it should sound like.

2. Tune the 4th string (closest to your face…
Tune the 4th string (closest to your face when playing) to G4 — note this is a higher pitch than the 3rd string, not lower, which is what makes this tuning "reentrant" rather than a simple low-to-high guitar-style tuning.

3. Tune the 3rd string to C4, the 2nd…
Tune the 3rd string to C4, the 2nd string to E4, and the 1st string (closest to the floor when playing) to A4 — giving the standard G-C-E-A order.

If using friction pegs, turn gently and expect to make small repeated adjustments across all four strings, since tightening one string slightly affects neck tension and can shift the others.

Recheck tuning before every practice session for at least the first few weeks with new strings — nylon/fluorocarbon strings stretch in noticeably during the break-in period.
What the steps above actually need
The reason a new ukulele sounds wrong is almost always the strings, not the instrument. West Music explains that a new ukulele comes pre-strung with nylon that has never been brought up to pitch, and it drifts because the nylon stretches and the knot at the bridge is still loose — "not to a fault in the tuners or the instrument." Expect one to two weeks of re-tuning.

D'Addario NS Micro clip-on tuner
D'Addario
Why it is here: Because fine-tuning by ear while the strings are still settling is how a beginner loses faith in the instrument. Reads vibration, not sound, so it works in a noisy room.
Clips to the rear of the headstock, out of the audience's sight. It reads the instrument's vibration through a piezo element rather than listening through a microphone, so it is "unaffected by surrounding sounds" — which is what makes a clip-on work in a noisy classroom where a phone app does not.
Get the right one: D'Addario publishes an accuracy of within 2 cents, and calibration from 410 to 480 Hz with A440 as default.
What we cannot tell you: D'Addario does not publish a tuning range for it.

Korg HeadTune HT-U1
Korg
Why it is here: The beginner-oriented alternative: it shows which peg to turn, and it detects low-G, which is the octave mistake beginners actually make.
Shaped like a ukulele headstock, with an LED that shows which peg to turn as well as a pitch meter — Korg positions it as "the ideal clip-on guitar/bass/ukulele tuner for beginners". It also detects low-G tuning, which matters because getting the octave right is one of the two real difficulties a beginner hits.
What we cannot tell you: Korg publishes no accuracy figure in cents for this tuner, and no calibration range. Neither does Snark for the ST-8. Of the four best-known clip-on ukulele tuners, two publish no accuracy figure at all and the two that do differ by a factor of twenty (D'Addario 2 cents, Peterson StroboClip HD 0.1 cents).

Aquila Super Nylgut ukulele strings
Aquila
Why it is here: If you would rather shorten the settling period than wait it out. Aquila states these stretch less than its Nylgut strings and are more stable from the start.
Aquila states these stretch less than its Nylgut strings, which makes them "easier and faster to tune" and "more stable right from the start" — directly relevant if the problem is a new ukulele that will not hold pitch. Also stronger, and less likely to dent against the frets.
Get the right one: Sizes soprano, concert, tenor and baritone, in high-G (re-entrant) and low-G sets. You cannot simply retune between them: Brad Bordessa warns that tuning a high-G string down an octave gives a flabby string, and tuning a low-G up an octave "will probably cause it to snap".
What we cannot tell you: Aquila's own stated drawback is that the strings are "rather soft". And neither Aquila nor Kala quantifies how much less these stretch, or gives a settling time — West Music says expect 1–2 weeks of re-tuning on a new ukulele with generic nylon strings.

Troubleshooting
Chords sound muddy or wrong even after tuning: double-check the 4th string is tuned to the higher G, not a lower one — this is the single most common beginner tuning mistake on ukulele. Pegs won't hold any tuning at all even right after adjusting: likely a friction peg that has worn loose and needs a technician to re-seat or tighten its mechanism.
Common errors
- !Assuming the 4th string should be the lowest pitch (like a guitar's low E) and tuning it down an octave instead of up — this produces a "linear" low-G tuning that is a real, valid alternative tuning, but not what standard beginner chord charts and songbooks assume.
When to stop and see a repair technician
If friction pegs consistently will not hold tuning even after gentle adjustment, or if a string buzzes against the fingerboard at multiple frets (a sign of neck or nut issues rather than a tuning problem).
