Standard ukulele tuning

Standard tuning is G C E A, from the string nearest your face to the one nearest the floor. A common way to remember it is My Dog Has Fleas. The G is tuned higher than the C, which is what gives the ukulele its bright sound.

How to tune a ukulele

  1. Tap Use microphone and allow access when your browser asks.
  2. Pluck the G string, the one nearest your face, and let it ring.
  3. Turn the peg slowly in the direction the tuner says until the note turns green.
  4. Repeat for C, E and A, then check all four again. New nylon strings stretch a lot, so expect to retune often for the first week.

Ukulele tuner questions

What are the ukulele string notes?

In standard tuning the strings are G C E A, from the string nearest your face to the one nearest the floor. Remember it with My Dog Has Fleas.

Why is the G string higher than the C?

Standard ukulele tuning is re-entrant: the G is tuned above middle C rather than below it. That gives the ukulele its bright, close-voiced sound. Low G tuning drops it an octave.

Can I tune a baritone ukulele with this?

Yes. Pick Baritone in the tuning menu. Baritone ukuleles are tuned D G B E, like the top four strings of a guitar.

Does it work on my phone?

Yes. It works in Safari on iPhone and Chrome on Android, as well as desktop browsers. Hold the phone close to the instrument and allow microphone access when asked.

Why can't the tuner hear me?

Usually the browser hasn't been given access to the microphone, or it is listening to a different input. The tuner will tell you which, and how to fix it. Play one string at a time, close to the device.

Is my audio recorded?

No. The sound is analysed on your own device in real time. Nothing is recorded, stored or uploaded.
