Ukulele Tuner

Tune your soprano, concert or tenor ukulele to standard G C E A. Use your microphone, or tap a string to hear its note.

How to use the ukulele tuner

1. Press Start tuner and allow microphone access. Nothing is recorded or uploaded.
2. Pluck one string and let it ring.
3. Needle left means flat, so tighten the string. Needle right means sharp, so loosen it.
4. When the note turns green you are within 5 cents. Move to the next string.

Tap a string button to hear its pitch and lock the tuner to that string.

Standard ukulele tuning: G C E A

Soprano, concert and tenor ukuleles use the same tuning. The G string is tuned higher than the C, which is called re-entrant tuning. It gives the ukulele its bright, close-voiced sound.

A popular way to remember it: Good Cats Eat Alfalfa. Or sing "My Dog Has Fleas", which matches the four strings in older D tuning.

Why does my ukulele keep going out of tune?

New nylon or fluorocarbon strings stretch a lot during their first week. Tune often, and gently pull each string away from the fretboard a few times to help it settle. Temperature changes also shift the tuning, so tune every time you pick the uke up.
