How to Tune a Ukulele: Step-by-Step Guide
Published April 12, 2026
Tune your ukulele in minutes with this clear guide. Standard tuning, alternate tunings, and tips for staying in tune.
Key Takeaways
- Standard tuning is G-C-E-A (high G re-entrant).
- Use a clip-on tuner or the Musoca Tuner for accurate, quick tuning.
- New strings stretch — retune daily for the first week.
- Always tune UP to the note, not down.
- Check tuning every time you pick up the ukulele.
Standard Tuning (GCEA)
Standard ukulele tuning is G-C-E-A (from top string to bottom). This is also called re-entrant tuning because the G string is tuned high, not low like a guitar.
String 4 (closest to your face): G4 (the G above middle C)
String 3: C4 (middle C)
String 2: E4
String 1 (closest to the floor): A4
The re-entrant tuning (high G) gives ukulele its distinctive bright, jangly sound. It also means chords ring out with a unique voicing you cannot get on guitar.
Tuning Methods
Electronic tuner (recommended): Clip-on tuners attach to the headstock and detect pitch through vibration. They work in noisy environments. The Musoca Tuner works great for ukulele.
App tuner: Phone apps use the microphone to detect pitch. Free and accurate in quiet rooms. The Musoca Tuner supports ukulele tuning.
Reference pitch: Play a known note (A=440Hz from a piano or online tone). Match each ukulele string to the corresponding pitch by ear.
5th fret method (no tuner): Fret the 4th string at the 5th fret — it should match the open 3rd string. Fret the 3rd string at the 4th fret — it should match the open 2nd string. Fret the 2nd string at the 5th fret — it should match the open 1st string.
Staying in Tune
New strings stretch. A new ukulele will go out of tune quickly for the first week. Tune it, play it, retune. Repeat daily until it stabilizes.
Tune UP to the note, not down. If the string is flat (below the note), tighten it up to pitch. Tuning down from sharp can cause the string to slip.
Temperature and humidity changes affect tuning. Bring your ukulele to room temperature before playing. Avoid leaving it in hot cars.
Check tuning every time you pick up the ukulele. Even 5 minutes of playing can shift the tuning slightly.
Practice Exercises
- 1Use the Musoca Tuner to tune each string: G-C-E-A. Practice until you can tune each string in under 30 seconds.
- 2After tuning, strum a C chord. It should sound clean and bright. If it sounds off, check each string again.
- 3Tune your ukulele, play for 5 minutes, then check tuning again. See how much it shifted.
Common Mistakes
- Tuning the wrong direction (down instead of up to the note). Always tune up to pitch.
- Ignoring the high G string. Many beginners assume it should be low. Standard is high G (re-entrant).
- Not tuning before every practice session. A out-of-tune ukulele trains your ear to accept wrong pitches.
Frequently Asked Questions
What if my ukulele will not stay in tune?
New strings need a break-in period (1-2 weeks of daily retuning). If it still will not hold tuning, check the tuning pegs for looseness, or take it to a music shop for a setup.
What is low-G tuning?
Low-G replaces the high G string with a low G an octave below. This gives the ukulele a wider range and a guitar-like bass response. Popular for fingerstyle playing.
Can I tune ukulele like a guitar?
Not exactly. Guitar is E-A-D-G-B-E. If you tune ukulele strings to match the top 4 guitar strings (D-G-B-E with a capo at the 5th fret), the chord shapes will be the same. This is called 'guitar tuning' on ukulele.
How often should I change strings?
Every 3-6 months with regular playing, or when strings sound dull, feel rough, or will not hold tuning. Nylon strings last longer than steel guitar strings.
