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.

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.
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).
