Know the target

The same GCEA names, a different fourth-string octave

High-G and Low-G ukuleles share the letters GCEA. In Low G, the fourth string is G3 instead of G4, and the open strings rise in pitch from fourth to first. C4, E4 and A4 stay at their usual pitches. Check the octave number as well as the letter: a green G4 reading does not tune a Low-G string correctly.

Use a Low-G string or set intended for your ukulele size. Simply loosening an ordinary high-G string by an octave can leave it too slack. If you are changing the string type or its fit at the nut, follow the string maker’s guidance; choosing a preset cannot make an unsuitable string set work.

Four clear steps

How to tune accurately

1Confirm that the fourth string is intended for Low G, then open this page’s tuner and allow microphone access.
2Tap the G3 string card to hold that target in Auto mode. Pluck the fourth string alone and mute the other three.
3Bring G3 to the center, then check C4, E4 and A4 in order. Let each clear reading settle in the green ±5-cent zone for one second.
4Play the four open strings one at a time and recheck G3. The pitch should rise through the entire G3–C4–E4–A4 sequence.

Reference: A4 = 440 Hz

Notes and frequencies

Physical string	Target	Frequency
String 4	G3	196.00 Hz
String 3	C4	261.63 Hz
String 2	E4	329.63 Hz
String 1	A4	440.00 Hz

Changing the tuner calibration recalculates every target from A4 = 415–450 Hz. The values above use the common 440 Hz reference.

High G versus Low G, string by string

Read this table from string 4, nearest your face in the usual playing position, to string 1. It describes physical order rather than sorting the High-G notes by frequency.

Only the fourth-string octave changes
String	High G	Low G
4	G4	G3
3	C4	C4
2	E4	E4
1	A4	A4

If G3 is difficult to read

Place the microphone where it can hear the instrument clearly, mute the C string, and use a moderate pluck. If the display jumps to G4, let the note decay briefly, mute it and pluck again with G3 selected. Avoid turning the peg by a whole octave just because the display momentarily catches a harmonic.

Practical answers

Frequently asked questions

Can I use normal ukulele chord shapes in Low G?

The string letters remain GCEA, so familiar shapes retain their chord names. The fourth-string notes sound an octave lower, changing the voicing and available bass notes.

Is Low G the same as Baritone ukulele tuning?

No. Low G is G3 C4 E4 A4; standard Baritone is D3 G3 B3 E4. Choose the preset matching the instrument and installed strings.
