Ukulele Standard Tuning (G-C-E-A)

Ukulele is a 4-string instrument. Standard tuning from string 4 is G, C, E, A. Known as 'high G tuning' because string 4's G is actually higher than strings 3 and 2. This is called re-entrant tuning.

High G gives ukulele its bright, cheerful character. Alternatively, 'low G' tuning drops string 4 an octave for a fuller range closer to a guitar.

How to Tune Your Ukulele

If this is your first time, follow these steps in order.

1. Open the online tuner

Select 'Ukulele' in the SnapRhythm tuner. Allow microphone access so the tuner can detect pitch automatically.

2. Tune one string at a time

Start with string 4 (G). Pluck gently and compare the detected note with the target.

3. Adjust the tuning pegs

Tighten the peg to raise the pitch, loosen it to lower. Turn in small increments rather than big jumps.

4. Re-check all strings

Adjusting one string can affect others, so double-check from the top once you finish.

Alternate Tunings

Besides standard high G, there are tunings worth knowing.

Low G (G3-C4-E4-A4)

Low G tuning. Closer to guitar feel

FAQ

What is standard ukulele tuning?
G-C-E-A from string 4 to string 1. String 4 (G4) is the highest note, which is unusual. This is called re-entrant tuning.
Difference between high G and low G?
High G has string 4 as the highest note (standard). Low G drops string 4 an octave to G3, giving a wider range and deeper bass — useful for fingerstyle and solo playing.
Does tuning change with ukulele size?
Soprano, concert, and tenor ukuleles all use GCEA. Baritone is different: D-G-B-E, same as the top four guitar strings.
Why does my ukulele keep going out of tune?
New strings stretch and drop in pitch for several days after installation. Re-tune often during this period. Temperature and humidity changes also affect tuning.
Can I tune without a tuner?
It's possible using 5th-fret harmonics or borrowing an A from another instrument, but a tuner is faster and more accurate — especially for beginners.
