Ukulele C-Tuning Tuning
The reference tuning for the ukulele: G C E A, low to high.
How to tune
Getting into C-Tuning
Work down the list in order — each string's tension moves the ones already set.
Allow microphone access
Asked once. Detection runs on your device; nothing is uploaded.
Play one string at a time
Let it ring open. A strummed chord gives the detector several pitches.
Centre the needle
Sharp means loosen, flat means tighten. Inside three cents is in tune.
Work up from string 4, one at a time
The lowest string carries the most tension, so setting it first means the rest hold. The panel below lists every target in that order.
Run through every string once more
Setting one string drifts the rest; the second pass makes it hold.
Strings
Every string at standard pitch
This is the reference every other ukulele tuning is measured against.
Select a string in Note Locking above to hold the tuner on it while you turn the peg.

The 4 open strings of Ukulele C-Tuning, lowest first, at A4 = 440 Hz. Each one is the pitch the tuner is listening for — G4 is G in octave 4.

| C4 | — | Do | 261.63 Hz |
| E4 | — | Mi | 329.63 Hz |

Sharps and flats share a pitch on a tuner: C♯ and D♭ are the same frequency, and which name you use depends on the key you are in, not on what the meter reads.
