Ukulele tuning

Standard ukulele tuning is G C E A from the 4th string to the 1st, a re-entrant tuning: the G string sounds higher than the C and E strings.

What is standard ukulele tuning?

On a soprano, concert or tenor ukulele the four strings are tuned like this, from the string nearest your chin (4th) to the one nearest the floor (1st):

StringNotePitchFrequency
4thGG4392 Hz
3rdCC4261.63 Hz
2ndEE4329.63 Hz
1stAA4440 Hz

So the 1st string is the A440 reference itself. C, E and G spell a C major chord: strummed open, the ukulele almost plays a C6 (C E G A). The classic mnemonic is "My Dog Has Fleas".

What does re-entrant tuning mean?

On a guitar, strings go in order from low to high. On a ukulele, the 4th string (G4) is higher than the 3rd (C4) and the 2nd (E4): the pitch order "re-enters" upward. The lowest note on the instrument is therefore the open C on the 3rd string.

This gives the ukulele its bright, tight sound: chords sit in a close register with no real bass. There is a "low G" variant with the 4th string an octave lower (G3), popular on tenor ukuleles for fingerpicking.

How do you tune a ukulele by ear?

First tune the 1st string to A440 (tuning fork, tuner, or the 5th fret of the high E string on a guitar in tune). Then:

  1. 2nd string (E), 5th fret = A: adjust the 2nd string until its 5th fret matches the open 1st string.
  2. 3rd string (C), 4th fret = E: tune it to the open 2nd string.
  3. 4th string (G), 2nd fret = A: its 2nd fret should match the open 1st string exactly, in unison.

Check: the 3rd string at the 7th fret gives G, in unison with the open 4th string.

How does ukulele tuning relate to guitar tuning?

The intervals of G C E A are exactly those of the top four guitar strings in standard tuning (D G B E), moved up a fourth. In other words, a ukulele sounds like a guitar with a capo at the 5th fret, minus the two low strings.

The practical upshot: a guitar chord shape played on the top four strings becomes, on ukulele, the chord a fourth higher:

Exercise: your first four ukulele chords

With these four open chords, play C, Am, F, G (I-vi-IV-V), four beats each at 80 BPM:

C, F and G are major chords and Am is their relative minor. To go further, the ukulele chord explorer shows every chord in G C E A tuning.

Key takeaways

Frequently asked questions

Is a ukulele tuned like a guitar?

Not exactly. It shares the intervals of the top four guitar strings, but a fourth higher and with a re-entrant 4th string. Guitar shapes work, but the chord names change.

Should I choose low G or high G?

High G (re-entrant) is the classic ukulele sound and what most songbooks and lessons assume. Low G adds a real bass and more range for melodies. Start with high G, you can switch strings later.

How is a baritone ukulele tuned?

A baritone is tuned D G B E, like the top four strings of a guitar, usually without a re-entrant string. The chord shapes are the same as on other ukuleles, but the names match guitar chord names.
