How to play Gaug on ukulele

Shape 1, 0-3-3-2, reading from the G string on the left:

Index finger: A string, 2nd fret (B).
Middle finger: C string, 3rd fret (D♯).
Ring finger: E string, 3rd fret (G).
Let the open G string ring (G).

Arch your fingers so their tips come down vertically. That keeps them off the open strings, which have to ring for the chord to sound complete.
On ukulele you strum all four strings. The top G string is tuned higher than the C, which is why ukulele chords sound bright and close.

Other ways to play Gaug

8-7-7-6: movable shape at the 6th fret, medium. A different set of strings gives a different color of the same chord.
12-11-11-10: movable shape at the 10th fret, medium. Higher up the neck it sounds brighter; handy when another guitar is already playing a lower shape.

Gaug the capo way

A capo turns an open chord into Gaug: capo on the 7th fret and play the open Caug shape (1-0-0-3). Handy when the rest of the song's chords also have open shapes in that position.

Em (vi in G major): Gaug (0-3-3-2) to Em (0-4-3-2): your index finger stays put, the middle finger slides across to the E string at the same fret, move the ring finger to the C string, 4th fret. Listen for G and B, which stay put while the rest moves. Em on ukulele
