Ukulele Tuner

Ukulele Tuner tunes soprano, concert and tenor ukuleles to standard G C E A with your microphone. The needle shows whether each string is too low or too high, and clicking a string plays its note so you can also tune by ear. Pitch is detected in your browser and nothing is recorded.

How to tune your ukulele

1. The tuner opens set to Ukulele (G C E A).
2. Click Start tuning and allow the microphone.
3. Pluck the G string, nearest your chin, and watch the needle.
4. Too low: tighten the peg. Too high: loosen it. Stop when the needle is green and the tuner says In tune.
5. Do the same for C, E and A, then check all four again.

Ukulele strings and frequencies

The 4th string G is higher than the 3rd string C. This “high G” or re-entrant tuning is what makes a strummed ukulele chord sound bright and close together. Some players fit a low-G string instead; to tune one, switch to Chromatic and tune it to G3, an octave lower.

Tips for ukulele

• Tune up to the note. Nylon strings slip back a little after you turn the peg. Go slightly below the note and come up to it.
• New strings need time. Expect to retune several times in the first sessions. Give each new string a gentle pull along its length to help it settle.
• Hold it naturally. Tune in the position you play; pressing on the neck or body can bend the pitch slightly.
• Check a chord. After tuning, strum C major (only the 3rd fret of the A string) and listen; it should ring clear.
• Tune by ear. Click a string in the tuner to hear its reference note and match the string to it.

Other ukulele tunings

• Baritone ukulele: D G B E. Use Chromatic mode.
• D tuning (A D F# B): an older tuning, one tone higher than G C E A. Use Chromatic mode.
• Low G: G3 C4 E4 A4, for a fuller bass sound.
