Soprano, concert, and tenor ukuleles share one tuning: G C E A. The G string is tuned higher than the C next to it, so the strings don't run from low to high. This is called re-entrant tuning, and it gives the ukulele its bright, close-voiced sound.

Low G tuning drops that G an octave for a fuller range, and a baritone ukulele is tuned D G B E, like the four highest strings of a guitar. The tuner above covers all three.

Tune to standard ukulele tuning by ear

Tune string 3 (C4) to a reference first: tap it in the tuner above, or use a piano or another instrument. Then tune each string to one that is already in tune:

Play string 3 at fret 4, then tune open string 2 until the two sound the same (E4).
Play string 2 at fret 3, then tune open string 4 until the two sound the same (G4).
Play string 4 at fret 2, then tune open string 1 until the two sound the same (A4).

Tips for tuning a ukulele

My Dog Has Fleas: The classic way to remember the four notes, sung on G, C, E, and A. Tap each string in the tuner to hear the real pitches.
New strings stretch a lot: Nylon and fluorocarbon strings keep stretching for days. Expect to retune often at first; gently pulling each string away from the fretboard speeds it up.
Tune the C string first: C is the lowest string on a re-entrant ukulele, so it makes the natural reference for tuning the others by ear.

Which string is which on a ukulele?

Holding the ukulele to play, the string nearest your face is the 4th, G. Then come C and E, and the 1st, A, is nearest the floor.

What is the difference between high G and low G?

High G is the standard re-entrant tuning, with the G string above the C. Low G tunes it an octave lower, to G3, so the strings run from low to high like a guitar's.

Can I tune a baritone ukulele here?

Yes. Pick Baritone Ukulele in the tuner: D G B E, the same as the four highest strings of a guitar.
