Short answer

Augmented chords feel floaty and uncertain. Raising the fifth of a major triad creates a symmetrical chord with no clear home, which suits transitions and dreamy film score moments.

How to use the G♭ Augmented chord

The G♭ Augmented chord is built from a root, a major third and an augmented fifth. Start at the root G♭ and stack the intervals to get the whole chord: G♭, B♭ and D. The same formula gives you the chord in any other key.

Augmented chords show up in jazz, bossa nova, film scores and psychedelic rock. They're often used as a brief transition chord, for example between I and vi in a major key.

How G♭ Augmented differs from similar chords

G♭+ raises the fifth of G♭ by a half step, so it stacks two major thirds and has no perfect fifth at all. That makes it the mirror image of G♭°, which stacks two minor thirds. Because three major thirds split the octave evenly, the same three notes form an augmented chord on each of them.

Where G♭ Augmented is used

An augmented chord is unstable by construction: it turns up as a passing tonic inside a descending line, and as a dominant sharpened to pull harder.

The descending line cliché: the fifth of the tonic rises a semitone, then falls into the third of the vi.

As an altered dominantC♭ major

  2. IC♭

Raising the fifth of the dominant sharpens its pull into C♭.
