Something wrong?

Tune your ukulele with the microphone of your phone or computer. The ukulele preset is already selected: press the microphone, play a string, and the tuner shows the note and whether it is too low or too high.

Standard ukulele tuning: G C E A

Frequencies for A4 = 440 Hz
StringNoteFrequency (Hz)
4th string (G, top string)G4392.00
3rd string (C, lowest note)C4261.63
2nd string (E)E4329.63
1st string (A)A4440.00

Soprano, concert and tenor ukuleles use the same tuning. The G string is higher than the C string (“high G” or reentrant tuning). With a low-G string, tune it to G3 instead.

How to tune a ukulele in 3 steps

  1. Press the microphone button and allow microphone access when your browser asks.
  2. Play one open string and let it ring. The tuner shows the note and a needle: left is flat, right is sharp.
  3. Turn the tuning peg slowly until the needle stays in the centre. Repeat for every string.

Tips for tuning a ukulele

  • New nylon strings stretch for a few days. Tune often until they settle.
  • Pluck with the thumb, not a pick, and let the note ring.
  • Tune up to the note: if a string is sharp, loosen it a little below the note and bring it back up.
  • Without a microphone, tap a note button under the menu to hear its reference tone and tune by ear.
