G Augmented Chord

Gaug stacks two major thirds, from G to B and from B to D sharp. The raised fifth keeps the chord from sounding like an ordinary major resting point.

Where does G augmented belong?

In C major, the raised fifth can sharpen the pull of a dominant chord.
Play the role cards to hear how its surrounding chords change the job it does; Diatonic Chords explains the basic numbered roles.

  • In C majorPushing dominant
    V+

    Raising the fifth to D sharp adds a note that climbs straight to the third of C.

    The fifth rises a half step at a time: a classic way to walk from G to C.

Progressions to try

    The raised fifth of Gaug intensifies the dominant before the final tonic.

    The line moves from an ordinary major chord through Gaug to a sixth chord before changing harmony.

Which shape should you use?

On guitar, start with the open 32100x grip. Let the open strings ring and keep any strings marked x silent. The xx5447 shape gives you another position when the neighboring chords sit elsewhere on the neck.

On ukulele, the open shape 0332 is the easiest place to start. The 4336 grip moves the chord to another register.

On piano, play G-B-D sharp. Move G up an octave to reach the first inversion, B-D sharp-G; the notes remain the same while the lowest voice changes.

What are the inversions?

G is the root, B the major third and D sharp the augmented fifth, eight semitones above the root.

  • Root position: G-B-D sharp, with G lowest.
  • First inversion: B-D sharp-G, written Gaug/B if B is lowest in the whole arrangement.
  • Second inversion: D sharp-G-B, written Gaug/D# if D sharp is lowest in the whole arrangement.

A slash chord names the note in the bass, not merely the lowest note under one hand. Chord Inversions shows how to read that distinction.

How does Gaug differ from G?

Keep G and B, then lower the raised fifth D sharp to D. That makes G; only one note has changed. Try that one-note change on piano, then use the comparer to hear it in the full chord. See G for the other chord's full spelling and roles.
