How to tune a ukulele with this tuner

  1. Choose your tuning (most sopranos, concerts and tenors use standard high-G G C E A).
  2. Press Start tuner, allow the microphone and pluck one string at a time.
  3. Turn the tuning peg until the needle centres and turns green. Tune up to the note from below.
  4. Go round all four strings twice — nylon strings drift as their neighbours are tightened.

Ukulele tuning tips

Why is the G string higher?

Standard ukulele tuning is "re-entrant": the G is tuned above C, which gives the ukulele its bright, chimey sound. Low G tuning drops it an octave for a fuller bass.

New nylon strings

Nylon and fluorocarbon strings stretch a lot for the first week. Expect to retune many times a day at first.

Baritone ukulele

Baritone ukuleles are tuned D G B E, the same as the top four strings of a guitar.

Tune by ear with reference notes

No microphone? Press any string button above to play its note for three seconds, then adjust the string until the two sounds stop "beating" (wobbling) against each other. Headphones or decent speakers make low notes much easier to hear.

FAQ

What are the notes for standard ukulele tuning?

G4 (392 Hz), C4 (261.63 Hz), E4 (329.63 Hz) and A4 (440 Hz), from the string nearest your face to the one nearest the floor.

Is this ukulele tuner good for soprano, concert and tenor ukuleles?

Yes. Soprano, concert and tenor ukuleles all normally use G C E A. Baritone ukuleles use D G B E, which you can select above.

Why does my ukulele go out of tune so fast?

Usually new strings stretching. Gently pull each string away from the fretboard and retune a few times to speed it up.
