How to Tune a Ukulele (Beginner's Guide)
Learn how to tune a ukulele in standard GCEA tuning. Simple instructions using a tuner or app.
Quick Answer:
Standard ukulele tuning is G-C-E-A (from top string to bottom when holding the uke). The easiest method is a clip-on tuner or free app like GuitarTuna. The G string is re-entrant (higher pitched than the C below it), which gives the ukulele its characteristic sound.
Tuning a ukulele is simpler than guitar since there are only 4 strings. Standard tuning (G-C-E-A) is used for almost all ukulele music. New strings stretch and go flat frequently - this is normal. With a tuner, getting in tune takes only seconds.

Standard Ukulele Tuning: GCEA
From the string closest to your face (4th string) to the string closest to the floor (1st string): G-C-E-A. Memory trick: 'Good Charlie Eats A lot' or 'Go Crazy Eat Avocados.' Important: The G string is high-pitched (higher than the C below it). This is called 're-entrant' tuning and gives the ukulele its bright, happy sound.
Using a Clip-On Tuner
Step 1: Clip the tuner to your ukulele headstock. Step 2: Turn on the tuner. Step 3: Pluck the G string (top string when holding uke). Step 4: Watch the display - it shows the note you're playing. Step 5: Turn the tuning peg until the display shows 'G' and is centered/green. Step 6: Repeat for C, E, and A strings. Tip: Turn pegs slowly - small adjustments are all you need.
Using a Tuner App
Free apps work great: GuitarTuna, Fender Tune, BOSS Tuner, and others have ukulele-specific modes. Open the app, select 'ukulele,' and play each string. The app shows which note it hears and whether you're sharp or flat. Apps work best in quiet rooms - background noise can confuse them.
Keeping Your Ukulele in Tune
New strings (especially nylon) stretch significantly for the first few days. Expect to tune often at first. After strings settle, tuning becomes more stable. Temperature changes affect tuning - let your uke acclimate. Geared tuners (look like guitar tuners) hold better than friction tuners (straight pegs). Always tune up to the note, not down - this helps strings stay in tune longer.
Troubleshooting Tuning Problems
Strings won't stay in tune: New strings need stretching time (3-7 days). Friction tuners slipping: May need tightening with a screwdriver. Tuner shows wrong notes: Make sure tuner is in chromatic or ukulele mode. String sounds completely wrong: Double-check you're tuning to the right note (G-C-E-A, not some other tuning).

Frequently Asked Questions
Why does my ukulele go out of tune so fast?
New nylon strings stretch for 3-7 days. Tune often during this period. Friction tuners can slip (tighten the screw slightly). Temperature changes also affect tuning.
What is re-entrant tuning?
Re-entrant means the strings don't go lowest to highest. On ukulele, the G string (highest position) is actually higher pitched than the C string below it. This creates the ukulele's characteristic bright sound.
Can I use a guitar tuner for ukulele?
Yes, if it's a chromatic tuner (shows any note). Guitar-specific tuners only show E-A-D-G-B-E and won't recognize ukulele notes. Most clip-on tuners are chromatic and work for any instrument.
