An augmented chord is a type of chord that creates a distinctive tense, unresolved, and dramatic sound. It’s based on a major triad where the 5th note is raised by a half step (semitone). This altered 5th is what gives the chord its augmented quality, creating a unique, unstable sound that seeks resolution.
The sound of augmented chords is often described as tense, mysterious, or even unsettling. Because the chord contains two major third intervals stacked on top of each other (root to major 3rd and major 3rd to augmented 5th), it doesn’t settle into a clear tonality, creating a sense of instability or suspense.
Their unresolved nature makes them perfect for moments that need drama. Augmented chords often act as a bridge or passing chord between stable chords.
The ambiguity of augmented chords can make them effective for moving into different keys.
Below are some augmented chords that can be moved around on the neck.
