Ukulele tuning

Open C (G-C-E-G)

Open C tunes the ukulele to G-C-E-G, a C major chord with the fourth string G reentrant. Open, it sounds a full C, which makes it a very comfortable open tuning for accompaniment.

The tuner opens already preconfigured; you only need to allow microphone access.

Strings and frequencies

How it sounds

It combines the reentrant character of the ukulele with the ease of an open tuning: straight one-finger barres give major chords all over the neck. It is ideal for simple strumming and first slide explorations.

Styles and genres

Recommended string gauges

Starting from standard C tuning and only moving the first string to G, a normal ukulele set works with no noticeable tension change.

Tuning tip

Learn the one-finger barre: in Open C, holding all strings at a single fret gives major chords you can slide around, a very fast way to accompany songs.
